My Samsung DLP Keeps Turning Off! Why?

I tried several searches to see if others have had the same problem as me and wasn't able to find any threads on point.

So, I have a Samsung HL-P5063W that I have owned for about 3 years and over the last several months it has developed a problem of just turning itself off. It can happen several times in an hour. After it turns itself off, I can usually turn it on again via the remote and may be good for an hour or longer, or it may turn off again in a few minutes. The problem seems to be getting worse lately and seems, oddly, more prevalent during the daytime than in the evening.

Anyone know what's the matter?

I suspect it may be the lamp or another part needs replacing (light engine maybe?), but really don't know. I'd like to determine the problem before I contact Best Buy where I bought it or Samsung (I don't have a lot of faith they will know the problem and just want to start replacing parts until it works again...).

Any thoughts greatly appreciated. TIA.

I'm sure you may have thought of this already, but have you tried blocking the IR receive port on the set to make sure it's not responding to some stray IR from something else?

I have friends who were concerned that a computer monitor attached to a PC in their living room was turning itself back on after they were sure they had turned it off. Turns out it was a Samsung PC monitor that had an IR sensor on it, and it was toggling on and off based on their usage of the remote control for their Samsung DLP TV.

Myself, I have a Samsung DLP TV also that's almost three years old, and about 6 months the same sort of thing was happening to me. It would shut itself down and the lamp error LEDs on the front panel would flash. I'd let it sit and cool off, then start it up again and it would run normally, usually for another week or so before repeating. That happened about four times, and then never again. I did move the set out from the wall another inch or so to make sure the fan intake wasn't being blocked in the back, so maybe I was having some kind of heat related shutdown and that's why it hasn't come back since. {knock on wood}

It does sound like it may be overheating, or the bulb is starting to go.

On the overheating, if you haven't already, vacuum all the vents in the back of the tv so you get the dust out. You probably don't want to remove the back to clean inside, but when you get to the bulb replacing, clean inside as well.

Thanks for the replies guys.

After my first post, I did some more online research and went to Samsung's website to read their FAQ. I was left with the impression that it was an overheating problem. Apparently these TV's are designed to turn off when they get hot.

So I pulled the back vent cover off for the lamp and looked inside. No real dust to speak off. Also, I was able to determine all the fans are working too. Vents are not blocked and, although the TV sits on a shelf in my built-in wall unit, there is about 12 inches of space behind it and it did not seem any warmer back there than the rest of the room. So overheating didn't seem like the obvious answer.

Then I read scoosdad's post (thanks! I was thinking this might be the problem). So I tried putting a piece of electricians tape over the IR remote receiver. Tried my remote and it wouldn't work so I figured it was blocked sufficiently. However, the TV set continued to turn itself off the next day -- albeit not as many times. After a few days of having the electrical tape on and the TV turning off a few times further, I figured IR interference is probably not the issue and took the tape off.

Here's the weird part. It hasn't turned itself off in about 2 days now...!

However, when I turned it off myself last night I could hear a buzzing sound that continued after the set turned off for a few seconds. Not sure if this is a fan problem or an indication that the lamp is no longer any good.

Any thoughts or further suggestions would be greatly appreciated.

Maybe I just replace the lamp and see what happens? If that doesn't fix it, I'll have the old one as temporary spare for down the road.

I guess I can call Samsung's tech centre and see what they have to say.

is it still under warranty from the manufacture (1 year since purchase date) or extended warranty from the store? if so, call them first, because if it's not a bulb issue, your just wasting that money and time, probably best to look at all your options (especially the cheaper ones) first, unless someone has a definitive answer for you.

On the lamp door there is a switch, that tells the TV the lamp door is closed.

The TV could be turning off randomly because this switch is defective.

Here is a better explanation.

The set heats up...
The plastic cabinet expands, creeks, pops...
The lamp hatch door switch trips...
Open and tightly close the hatch door.

Many times your problem can be solved by opening the lamp cover door and adjusting the safety shut off switch that is used to turn off power any time the lamp cover is removed.
Found here: http://forum.ecoustics.com/bbs/messages/2/357440.html

Be sure the switch is lined up correctly, and then replace the cover. A lot of the time that will fix your problem. If it doesn't fix it you will have to call for service.

Thanks for the additional info.

I will check the lamp door as I have noticed that when I have opened before to yank out the bulb, the set seems to not turn itself off as frequently. So maybe the process of opening and closing that door realigns the switch slightly so the set is not as fussy...

I will let you know if that works.

Does it make any sound at all, any beeps, when it shuts down? My crappy DLP did that and it turned out my lamp was over heating, but also it was doing that because it was under the window and sun was hitting it.

Make sure u dont have it near a heat vent or direct sun.

Is it possible that the firmware needs to be updated? I know that's an issue with other Samsung models.

On August 2, 2008 I had a professional installation of my new LN52A550p3fxza-52" 1080p Lcd tv. I bought a new bluray player with power surge protector, monster cables and I even spent the $20 for the screen cleaner!! I am sure I made the sales mans day!

My problems started the night of the Olympic opening ceremonies, it turned off 2 separate times and then reacquired the signal about 15 seconds later... since then it has happened only once..not a big deal..

Tonight 8-27-08 my tv is inoperable. It turns on... then turns off.... turns on.... then immediately turns off... I spoke to a samsung rep and he finally agreed that it was defected.. he said it was an internal power supply problem and a service technician would have to fix it..

Unfortunately I have invited 15 people to my house for the first huskers game on saturday... I will follow up with everyone how samsung treats me...

Needless to say im very disappointed... If anyone can help please let me know... I am trying to keep it cool by pulling it away from the wall... but I found on another forum that it is a defect with many Samsungs.... sigh... nothing like spending 3g and 3 weeks later having it be broken...

Don't be silly. Return that TV set as a problem now may be a small taste of things to come. I'd also recommend a plasma if you're an avid sports viewer.

Welcome to the forum! :hithere:

I would exchange the display since it is within the 30 day return window as Codes20 stated above. It may be a sign of problems to come also. I would not take no for an answer from the store either.

I also agree that if you watch a lot of sports you might want to consider buying a plasma instead of that LCD. when you exchange/return it.

Good luck!

I've had this problem on occasion where it would just happen once in a couple weeks to a couple times a day. I ended up opening up the whole back panel and carefully cleaning out the fans, heat sinks, etc.

Even then, the air coming out of the exhaust was quite warm to almost being hot. I'm a PC tech and know all too well how bad heat is for electronic components so I picked up a high quality 120mm X-Flex Scythe computer fan and wired it up to an 9v 300mah 12v AC Adapter from Fry's and plugged the ac adapter into the wall and used some double sided 3m foam tape on each corner of the fan to stick it so it EXHAUSTS the area where the hot air comes out the duct away from the bulb.

DO NOT use active fan cooling as an INTAKE at that location or any other location. You wont get proper air circulation inside the TV.

I picked a 9v converter because a 12v would have been 1600rpm, 28dba, and blow 67cfm of air out of the Tv. With the fan under-volted at 9v, it's running at around 1200rpm and is virtually silent but still moves probably about 60cfm or so.

With the added airflow and component cooling, the exhaust air is nearly cold PLUS the life of the TV's components will be much longer.

I can take a few pictures for you guys if you'd like. I'm not home at the moment.

acmeex, did you solve your problem? I had the same situation with my Samsung DLP which is just over 4 years old, & a fews weeks beyond the BestBuy extended warranty. My set started turning off for no reason. I contacted live chat with Samsung, & the tech support instructed me to try a different electrical outlet. I didn't waste my time on that brilliant idea. I took the back cover off, and propped a flashlight against the safety switch, which just tricks the set into thinking the cover is still on. That solved my problem & I'm going on a month now.

Hi

I am new to the forum beacuse... ta-da! -- I have a problem (similar to acmeex).

I have a Samsung HL-P4674W. Bought in 2004. It has been trouble-free for 4+ years. I have read the entire thread and there are a lot fo good ideas/suggestions. I do not have any IR interference. Fan works. No dust buildup (no heat issues).

In essence, I lost the picture the other day. So, I figured it was time for a new lamp (lights blinking) even though the set does NOT get a lot of heavy-duty use. Ordered a lamp (BP96-00224J -- which is the same as the "C" unit). Lamp arrived this morning. Swapped-out the lamp, but... I still get a single blinking center LED ("lamp"). This goes on for maybe 30 seconds and then I get three blinking LEDs. According to the owner's manual, this means "Lamp may be defective; please contact a certified technician."

Hmmmm.

:confused:

Any insight/ideas would be appreciated.

I would contact a service tech. Could be the lamp power supply, the lamp ballast, or something else.

The service tech showed-up on Friday...

Had to replace the DLP chip/board.

$500+ for the part.

About $150 for house call and install.

Ouch.

But it works again!

If it would have been a couple hundred more... I would have considered a new set -- I have seen some nice LCD and plasma units priced in the $1000-$1250 range.

I have this very same issue. It's so annoying! Especially when you want to sit and watch a show and it starts turning off every 5 minutes. My mom just had her SONY fixed by a SEARS tech that came to the house so I asked him about MY SAMSUNG. I've done everything that I've read on the net too...thinking it was overheating and vacuumed out the dust, etc. Anyway, the tech asked me if I could hear an annoying noise when it started up and I said YEAH....he told me that it was actually the COLOR WHEEL. I don't know why it would cause it to turn off or make that noise but that's just what he told me. I still haven't taken mine in but I thought I'd just let you know what he told me. He said it was a known problem with those Samsungs.

GLuck.

I have the Samsung HLS5087WX DLP and have a similar problem, but mine is the opposite of overheating.... My set is almost 3yrs old and when I turn the tv on cold(meaning, set was off all nite), it turns on, then shuts off between 20-60 seconds later, immed followed by flashing lights on front panel. I have to wait 30-60 sec to try again and this sometimes takes about 10-15 attempts before it stays on. Once it's on, I tried shutting it off and 1 min later it turned back on, so it's not overheating related. We currently have been leaving the tv set on all day and night because of the hard time it is turning it back on.
I had a service tech in to look at it and since the set was on at his arrival, it didn't reproduce the problem. He said it could be color wheel. I called the service center back to reschedule, so I can schedule the tv to be off all day until his arrival for him to see it, and they said they are waiting on a replacement color wheel part to arrive. Odd, I thought, since the tech never actually saw the tv produce the problem in front of him. I hope this is the resolution. I will see what happens after replacement and post results. Thank god I have the 5yr ext warranty from Crutchfield.

We have had the tv for around 3 yrs and the warranty is up. After about six months the tv did the same thing, a tech came out 3 times and couldn't fix it. Samsung sent another tech that replaced the entire board and it worked. I don't understand why there wasn't a recall it seems to me there are thousands of people out there with these tv's that have nothing but problems. Any suggestions are appreciated, thanks.

They are replacing the light engine and from what I understand consists of the color wheel, dlp chip, lamp, ballast & other components. I thought they were replacing only the color wheel, this is great. I will reply back when the work is done.

Wish I'd seen this forum before I bought the latest and greatest (or so I thought) Blu-ray system (HT-BD1255W) from Samsung.
Only had the thing for 6 weeks and, you've guessed it, it now switches itself off after about 2 minutes with the helpful 'PROT' message on the screen. Tried contacting Samsung support - obviously only Mon-Fri hours and half day on Saturday. "My Samsung" website also throwing up a server error.
I can't believe the thing is overheating - it has so much space around it, it must get lonely!
Hopefully Samsung will come to the rescue when they can be bothered to provide customer support tomorrow!

My HLP5063w..which I have had for over 5 years has been turning off recently. The weird thing is...It NEVER switches off when watching cable TV off of my DVR.
It only switches off when either watching a DVD or playing the Wii.
How can an input make a difference?

It doesn't always turn off....but has been recently. I could not even watch a DVD the other day because of the constant interruptions. Seems to happen more when watching a DVD (DVI input) as opposed to the Wii (Component).
Cable's input is HDMI.

Help!!!

I hope this helps somebody. My samsung 72" dlp would turn off and on. The remote could not turn it off so i had to unplug it. The image would last a few seconds then turn off then on. This would happen repeatedly until the red and green lights would start blinking then no image. The solution that helped me was I replaced the power board, ballast and lamp. Make sure the ballast you get is the same exact one as in your tv (I used a replacement one at first and it produced a flickering color image, but the TV was on and didn't turn off). If one of these components was not replaced it would continue with the same problem. The lamp was only a year old it worked fine, but for some unknown reason all three had to be replaced. My tv is working fine now. This isn't cheap, all three cost me almost $400 including shipping. My TV is 1.5 years old.

I have an old 2004 Samsung 46 inch dlp, and found early on that the
switch within the door to the lamp sends mixed signals, and will some
times shut the set off. I fixed the problem by adding a little electrical
tape to it. It makes the sw just a little bigger, making the dlp not
allowing the switch to go to the off position as easy. Mine hasn't
shut off by itself in years.

Our 50" Samsung DLP will be 4 yrs old in December. It just started turning itself off about 2 months ago. It has probably happened about 7 times over the past 8 weeks. We will take all of the suggestions on this thread into account and hopefully the problem will be solved without having to call in a tech!

Good luck & hopefully those ideas will work for you. I wonder if it is a heat issue so make sure you vacuum out the air vents first to see if that fixes the problem.

If your Samsung DLP keeps turning off, please read this, a small piece of tape can safely and effectivly fix the problem and save you lots of time and money.

Remove the lamp access panel, tape the blue door switch to the DOWN position, put the access panel back on.

After about 4 years, my Samsung DLP started turning off by itself. I figured that years of dust buildup was causing overheating issues. I used some canned air and sprayed everything out.
DO NOT spray when the lamp is hot or if the tv is plugged in or on, doing so will create new problems for you including the lamp breaking or shorting out circuits. I myself became very frustrated and impatient one day and sprayed air in the rear while the tv was on, luckily, after a fireball shot out the back of the tv and everything turned off, it somehow still worked and came back on. It was a stupid mistake that nearly cost me a tv.
Also, do not make the incorrect assumption that just because it is unplugged, that there are no electical hazards, that asumption is wrong. Capacitors hold electric charges, even while unplugged, a hand or tool can complete a circuit and it will release the charge, this can damage your tv and seriously injur you. Do not try getting your hand or a tool back through little gaps trying to clean things off or just to look around, you can electrocute yourself on an unplugged tv, and other electric devices.
I have also read several posts about disconnecting the heat sensor, DO NOT do that. If your tv is actually overheating, it is what is protecting the tv from burning out and your house from burning down.
After dusting and making sure all of the fans still worked, I had about an hour that I thought the problem was gone. It was not, it kept turning off.
Next I moved on to the lamp, they do have a lifespan and are recomended for replacment after around 4 years, which was about how old mine was. If you need one, you will probably have to order it online, they range from $70-$200, shop around, I got mine from mwave.c for $80.
WHEN ORDERING A LAMP get the part number off of the sticker on the side, or rear of your tv, it says "LAMP" and lists the part number. I ordered mine based on the tv model number, I have come to find that every website has the wrong lamp, and housing, listed for my model tv. Fortunatly while the housing didn't fit, the lamp was the same so I changed it out in the old housing. Many sites offer, for up to
$70 extra dollars, a lamp in a housing, DO NOT PAY FOR A HOUSING unless you really need one, swithing the lamp in the old housing involves 6 philips head screws and about 30 seconds, it's as much work as taking the housing out of the tv.
Unfortunatly, changing the lamp also DID NOT stop the tv from turning itself off, however it was a worthwhile purchase, the picture is brighter and everything looks sharper, comparing the old lamp to new, you can see a haze on the old mirror and glass cover which would affect the light output.
Anyway, now with a dust free, fans working, new lamp tv, the thing still kept turning itself off.
I had read several posts about the door switch being an issue for people, I didn't think the symptoms had anything to do with it, the flashing "lamp" and "temp" lights in the front of the tv had me convinced those were the problems.
Apparently, the correct position for the switch is down, once the cover has been removed, it is almost impossible to put the cover back on with the switch down, that is where the tape comes in.
I didn't have anything to lose and it didn't cost anything to try so I taped it down and put the cover back on. It has been 2 weeks so far since doing it and that tv hasn't turned itself off since, it was previously turning off about twice and hour so I feel pretty good that the problem was the closed position of the switch. The fact that it developes into a problem over time has something to do with the expanding and contracting of parts and plastics over years of use and the switch supposing to be down instead of up.
Hope this helps someone.

also i took the samsung and was working on it today at work, i took off the lamp cover and tripped the switch with a screw driver, and reseated the lamp and the tv turned on and worked i watched a movie and it played sound and worked great so i turned it off and turned it back on and it worked the second time but third time was not the charm, now i have just the green blinking lamp light again, fans turn on but the color wheel does not spin, anyone know why, or is there any way to check voltages on points to make sure its getting the required power? its a brand new color wheel and bulb so those should not be a problem.

any ideas on my prob? plz help. again just for more detail, my samsung HLN4365WX/XXA. I have replaced the bulb (brand new >1hr on it) And ive replaced the Color Wheel (again brand new >1hr on it) and it still does not work, the green lamp led on the front of the tv just blinks on and off constantly. The only way to turn the set off is to unplug it. i tried entering service menu to see if the bulb just needed reset. The tv set turned on and i heard the startup tune but the led kept blinking and nothing happened. While working yesterday i started messing with the samsung again, i opened the lamp cover and tripped the door switch with a screw driver and pulled out the lamp and reseated it, turned the set on and it worked for about two minutes. I shut it down and tried restarting it and it worked a second time. Pleased with the results i started reassembling the tv and turned it on once more and now i have the same problem. So i broke down and took the tv completely apart, when i turn the power on the only noise is the cooling fans. the color wheel does not spin. i checked the voltage from the power to the ballast and it has the appropriate amount. i do not know what is wrong and why my color wheel will not spin. please help. thanks,

Could be a door switch where you replace the lamp is not closing properly.

so the lamp door switch works because the tv registers it when the lamp door is open. so i completely tore the tv apart, all boards everything out of it. al seems to be well, everything looks good. now whilst looking everything over i saw on what appears to be the main power board. there a massively big capacitor made by samwha, its green and gold. unlike the other capacitors the metal top seems to be covered with plastic and is bulging at the top. i dont know if its just the way the cover is. it looks like a 450w. i have a couple pics but they are from my phone. could this be the problem?
pm me and ill send the pics

Can the plastic cover on that cap be removed?

actually just about to post, yes the cap can be removed and turns out the capacitor is not blown :-( almost woulda preferred it. well i dont know what to do anymore. the lamp light blinks, but the color wheel does not even bother to start and its brand new. lamp is brand new. so i dont know what to do.

PFC5
10-20-2010, 11:33 PM
You might want to get a service manual to see what the start up sequence is. It could be the color wheel (or the motor that spins it) is bad, but it could be that something else is faulting out so it never starts because it comes after the faulty item in the start up sequence.

deadlydayne
10-21-2010, 06:27 AM
arent the samsungs supposed to start up as the color wheel then ballast and then lamp?
also dont know if this helps but everyonce in a while i get the startup tune to play but nothing happens afterwards

We've been having the "TV turning itself off" issue now for a few months. The last 2 weeks it became ridiculous - turning off after being on for 10 seconds!

We read through this entire thread and taped the switch down a million different ways. We also cleaned out all the dust. Neither solved the problem.

So, we followed what some previous posters said and using the exact lamp info on the label on the side of our TV, we ordered a brand new bulb with the housing from Discount-Merchant (I'm not allowed to post the entire URL because I don't have enough history on this site??) It was $119.

My husband installed it today and VOILA....problem is solved :banana:

This was SO QUICK & EASY! Our Samsung DLP HL-S6186W kept shutting off -- any time we turned it on (it just kept getting worse as time went by).

We did what Made To Break suggested... we opened the lamp cover in the back of the TV (it's probably 5" x 5" with only one screw) vacuumed everything while we were at it and used a piece of black electrical tape (1") to tape the little blue lever down. (You don't have to touch anything else -- he kind of scared me with his electrocution talk!) VOILA!! Problem fixed!!!

THANKS "MADE TO BREAK" you MADE MY DAY!!! :yippee: LOL!!!

Hi, I have a Samsung UN46B8000XF LED/LCD. I bought it in December 2010 and for the past 2 months it has been turning off a few times a night. When I turn it back on it would come on right away until 2 nights ago when it went off and wouldn't turn back on. Now there is a clicking sound like it is trying to turn itself on but nothing happens so I unplugged it and everytime I plug it back in I get the same constant clicking. I read other responses regarding Ballasts and Color Wheels and Bulbs but I don't rcognize the model numbers. Does this sound like it could be a Ballast problem for my model too? I would really appreciate the help. Thanks.

My DLP has started to do this as well. It is about 4 years old, and had started turning itself off occasionally about 3 months ago. Now it does so for the first 2 to 3 hours I use it, but it takes longer each time, and eventually stops, making me think it is not a heat problem, or a problem with the sensor.

Any thoughts would be appreciated.

I have a 56" HLP5663W that every now and then would turn itself off shortly after being turned on. About a year ago I put in a new lamp thinking this would help. It didn't really, would still happen once in a while. Now, however, it happens every time I turn on the tv. Sometimes I only need to turn it back on once or twice but sometimes as many as 9 times in a row before it will stay on. Once it decides to stay on it's good until you actually turn it off but it's really frustrating to have to keep turning it on.
Any help would be greatly apprecitated.

Ok, I have a 46" LN46A650 LCD. A little over 3yrs old. Never had a problem with it. Last Friday night, out of the blue, it started making this loud buzzing noise, so loud I could barely hear my husband talking over it. We immediately turned the TV off and it stopped. Left it off for a couple of hours, thinking it had overheated or something. Turned it back on later that night, picture was fine, but no sound, only a quieter buzzing. Then it started turning itself on and off. We unplugged it and left it overnight. Next morning, turned it on, sound was fine, but picture gone, only vertical lines running all across the screen. Left it off and unplugged all weekend, tried again today, picture and sound came on for about 4 seconds, then the screen froze and kind of jumped around and sound went out. Any ideas??

I have an older Samsung DLP Model#: HLM507W1 and had the same problem of it going on and off. Took the large panel off the back and used a zip tie to lock the blue "lever" switch in the closed position. Solved the problem.

It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

i have a 7 year old 61" DLP SAMSUNG MODEL # hlp6163. i changed the lamp and the color wheel in the past two years. Recently i have had my tv shut on and off while playing a blu ray movie on my ps3. The TV is fine while on cable which is run via component cables, however with the HDMI PS3, the TV immediately shuts off and on with no stopping unless the HDMI is unplugged. There is no noise or humming sound, just the tv going on and off repeatedly. HELP PLZ.

ive read most of the problems posted in this thread but i cant seem to find the problem to mine...

it would turn on when i plug it in on its own, when the picture turns up in 1 sec it would freeze and restart constantly until i unplug it and when i plug it back in it would continue...

i have a Samsung HLR5067WAX/XAA

about a month ago i got a new lamp for it and it was working great.

tonight when i got home i turned it on and it started doing this...

it doesnt make and noise at all. i checked the door switch in the back.
i tried everything and i got no results... techs charge to much for little things... im a tech myself but on computers, this tv is being tricky...

any help is very much appreciated...

Hello. We have a 7-year old 4663 DLP that we don't want to throw out (these early HDTV's have a pretty good picture and handle motion well; the Roaring 00's are over and things need to last). Thanks to he or she who posted to make sure the lamp door is seated (can't find the post). I reseated the door, evenly tightening the four screws for a flat fit (after blowing out the innards and vents with clean compressed air). So far, so good. Is it possible that heat alters the tiny plastic arm that must be pushed up or down to tell the TV the door's in place? I guess Samsung's afraid somebody will stick a hand in the lamp area when the TV's on. The Lumati (if anyone knows who they are) would probably say Samsung should let nature take its course :offtopic, but I digress). Anyway, the TV's been been on long enough to watch a highly annoying NFL game that'll hopefully be over before our home team loses the lead. Thanks again!

Hello, I had the same issue, with the identical model television. I tripped the switch by putting a piece of cardboard where the green trigger is, so I could allow access and airflow by removing the lamp panel. I had similar noises to you.. most likely my fan sucking. But now that the panel is removed, the lamp does not overheat.

I know this is from several years ago, but hopefully it will help someone like you guys helped me.

Thanks a bunch

Hi, I have a Samsung 61" alp HLS6186WX

After months of my tv shutting down and 2 (standby/temp, lamp)out of the 3 lights (standby/temp, timer, lamp) flashing after shutdown, and also replacing the bulb, I believe I may have found a solution for all of us!

I recently heard/read that the switch behind the cover used to replace the bulb could be the issue. So I tried a test. I removed the cover to allow the switch to open, pressed the power button and got the same 2 flashing lights! So then I placed a pen on the switch to keep the switch depressed, pressed the power button, and boom, the tv turned on! No flashing lights!

Sorry if I have posted this wrong, I admit I didn't read the forum rules. I don't know if there are any repercussions of messing with the switch or leaving the cover off. So please remember this might not work for everyone and certainly don't try poking around inside your tv with it plugged in!

Tv picture will go blank (black) no picture unexpectedly but still have sound and Tv will stay on, no error codes, no blinking lights, no error codes, reacts to remote as usual - vol up/down, channel change, A/V source change. Can stay on for an hour or maybe 2, other times it may be 30 mins or maybe just 2 mins, irregular times from cold/hot start. Picture perfect when it does work - not black and white or spotty or distorted picture.
The lamp will stay on, the fan (is there only 1 fan?) will stay spinning with no grinding or unusual noises, the colour wheel remains spinning with a slight whirring as it spins down when powering unit off by remote control.
Tried different input sources - Wii console, Sky box (not HD or Plus), Freeview box, standard DVD player but still the picture goes off.
Cleaned out some dust build up from cooling fan/ducting and ballast.
Tried to bypass the 5v prot. ctt on the lamp ballast but still the picture goes off.
Tried bypassing the thermal sensor but still the picture goes off.
Tried removing all IR sources and covering IR sensor on Tv to eliminate other signals but still the picture goes off.
Reluctant to replace lamp as it remains on so can't see it being at fault and the ballast lights the lamp and the lamp remains on with either the prot. cct bypassed or not so can't see it being the lamp ballast either.
Tried running Tv with rear panel on and off but still the picture goes off, thought this might reduce heat build up on other components which might shut down due to over heating issues but still the picture goes off.
Service menu was showing lamp hrs at 11,000 but have now reset to zero hrs.
Help would be greatly appreciated!

The bulb is brand new. OEM Philips. The dust has been cleaned out of it.
The LED's Some times have the Standby/Temp blink once and the Lamp blink twice.
Or.
Nothing blinks. However the Standby/Temp light stays lit.

I am thinking perhaps it is a heat problem. I put my hand behind the TV and did not feel much air flow.

Any ideas?
If it is heat I was thinking of upgrading to a computer case fan that produces more airflow while keeping the db's down.

So today I had the tv on with split screen (half AV input via sky box, half teletext) all day without the picture going off but as soon as I put the screen back to full size the picture went black again within 5 mins. Now its back to split screen for this evenings viewing, still all ok but defeats the point of having a 50" screen.
Maybe others with similar issues could try split screen to see if it is the same for them.

Don't know if this applys to you but if you have purchased anything but Osram or Philips replacement lamp for your DLP tv then this is probably your problem.. The generic is VERY tempting in this recession but in this case generic is poison to your dlp tv... i have a Mitsubishi 60735 and went thru 2 generic bulbs when my tv kept shutting down on it's own and the lights on front would flash, i could cut it back on for 10 minutes then flicker and shut down again ..well since the bulb was new i thought it may be defective so i got is exchanged for another one ... after all of the post i have seen how much repairs were going to cost on dlp sets no matter what the problem was ..i was ready to chunk the tv out the door when the second lamp was doing the same thing.....!! well a last ditch effort to save my tv before i trashed it or taking it apart to dissect it.. was to buy a brandname lamp ... in my case i purchased a Philips ..it cost twice as much =/ ..i could just return it if it didn't work.. well it was the generic lamps that was causing trouble.. the brandname worked perfectly .. i am just glad the generic lamp didn't do any damage to my TV!!! I have done further research on the generic lamps and realized that the damage it could have done was not worth the money i saved when i purchesed it... Generic is a great deal In some cases (household cleaners, etc..) but in this case GET THE NAME BRAND!!!! the only name brands i know of for these lamps are Philips or Osram/Sylvania.. hope this helps others from this headache. Do your research don't by generic lamp replacements, your DLP set cost to much to risk it.

I would like to thank everyone who posted this fix for the most annoying problem of the Samsung tv turning itself off. My DLP tv, purchased in 2005 began turning itself off repeatedly a few months ago. I looked up the problem, contacted Samsung, whose support person never heard of the issue, but would send out a service tech for lots of $$$. I declined, and called my own tv repair person, who could not find a problem, as my bulb had been recently replaced, and the area cleaned. But the problem ceased, albeit temporarily, after he left, but reoccurred a few weeks ago. I, like others here, love the picture quality of this tv, and wanted to try and keep it. So, I tried the electrical tape on the blue switch, and the TV has stayed on without turning itself off. It certainly is worth a try for anyone with this issue. I again would like to thank everyone who posted this solution.

If your Samsung DLP keeps turning off, please read this, a small piece of tape can safely and effectivly fix the problem and save you lots of time and money.

Remove the lamp access panel, tape the blue door switch to the DOWN position, put the access panel back on.

After about 4 years, my Samsung DLP started turning off by itself. I figured that years of dust buildup was causing overheating issues. I used some canned air and sprayed everything out.
DO NOT spray when the lamp is hot or if the tv is plugged in or on, doing so will create new problems for you including the lamp breaking or shorting out circuits. I myself became very frustrated and impatient one day and sprayed air in the rear while the tv was on, luckily, after a fireball shot out the back of the tv and everything turned off, it somehow still worked and came back on. It was a stupid mistake that nearly cost me a tv.
Also, do not make the incorrect assumption that just because it is unplugged, that there are no electical hazards, that asumption is wrong. Capacitors hold electric charges, even while unplugged, a hand or tool can complete a circuit and it will release the charge, this can damage your tv and seriously injur you. Do not try getting your hand or a tool back through little gaps trying to clean things off or just to look around, you can electrocute yourself on an unplugged tv, and other electric devices.
I have also read several posts about disconnecting the heat sensor, DO NOT do that. If your tv is actually overheating, it is what is protecting the tv from burning out and your house from burning down.
After dusting and making sure all of the fans still worked, I had about an hour that I thought the problem was gone. It was not, it kept turning off.
Next I moved on to the lamp, they do have a lifespan and are recomended for replacment after around 4 years, which was about how old mine was. If you need one, you will probably have to order it online, they range from $70-$200, shop around, I got mine from mwave.c for $80.
WHEN ORDERING A LAMP get the part number off of the sticker on the side, or rear of your tv, it says "LAMP" and lists the part number. I ordered mine based on the tv model number, I have come to find that every website has the wrong lamp, and housing, listed for my model tv. Fortunatly while the housing didn't fit, the lamp was the same so I changed it out in the old housing. Many sites offer, for up to
$70 extra dollars, a lamp in a housing, DO NOT PAY FOR A HOUSING unless you really need one, swithing the lamp in the old housing involves 6 philips head screws and about 30 seconds, it's as much work as taking the housing out of the tv.
Unfortunatly, changing the lamp also DID NOT stop the tv from turning itself off, however it was a worthwhile purchase, the picture is brighter and everything looks sharper, comparing the old lamp to new, you can see a haze on the old mirror and glass cover which would affect the light output.
Anyway, now with a dust free, fans working, new lamp tv, the thing still kept turning itself off.
I had read several posts about the door switch being an issue for people, I didn't think the symptoms had anything to do with it, the flashing "lamp" and "temp" lights in the front of the tv had me convinced those were the problems.
Apparently, the correct position for the switch is down, once the cover has been removed, it is almost impossible to put the cover back on with the switch down, that is where the tape comes in.
I didn't have anything to lose and it didn't cost anything to try so I taped it down and put the cover back on. It has been 2 weeks so far since doing it and that tv hasn't turned itself off since, it was previously turning off about twice and hour so I feel pretty good that the problem was the closed position of the switch. The fact that it developes into a problem over time has something to do with the expanding and contracting of parts and plastics over years of use and the switch supposing to be down instead of up.
Hope this helps someone.

It WORKS!!!!!! After months of frustration with my Samsung 50" projection TV turning off all by itself a simple piece of tape on the little switch stopped it. I have to assume it is a heat sensor switch that is defective because the TV has plenty of ventilation and the area is cool, always. Thank you so much for the tip...I'll repeat it here and all you need is a phillips screwdriver. Remove the lamp access panel in the back of the TV. You'll see a tiny blue switch. Flip it down, use some duct tape to hold it there, replace the panel and VOILA! You are done. The TV will now stay on.

My 2007 Samsung DLP also started turning off and on every 30 seconds or so. I replaced the bulb about 6 months ago, so I don't think that is the problem. I put a room fan behind the TV to see if it would help keep it cool. It has not shut off since. What could be causing the overheating?

My TV began turning itself off again after a few months. It occurred to me that the electrical tape may have come loose from the switch, and sure enough, that was the problem. When the tv would shut itself off, I believe I heard a click. I retaped the blue switch back down, and the tv is no longer shutting itself off.

As others are talking about, the blue switch on the lamp door in the back can be an issue as well as the lamp and of course overheating. Here is what I have done to resolve the issue of the TV randomly cutting off.

1.) Fix the switch issue: Unplug the TV. Open the lamp door. Clip the wires on the lamp door switch (I clipped about mid way in the wire so I could reconnect if needed), strip the wires and twist them together. Add a wire nut and/or electrical tape. Free and instant fix to the blue lamp door switch issue.

2.) Install an additional fan to prevent overheating: I installed a typical square computer case fan in the rear of the TV and powered it over USB on the TV so it would cut off when I turn off the TV. I used a 12v fan even though the USB port only provides 5v of power. The fan doesnt run as fast as it would with 12v but it still provides circulation.

So to do this, take an old USB cable and clip it. Strip it down so you can see the wires inside. The red and black are all we are concerned with. Ignore the green and white wires and the outer silver shielding wire. Strip the fan wires and twist red to red and black to black. Wire nut and/or tape on the connections. To test, plug it in to your PC. Fan should power up.

Next install the fan in the TV. Make sure the air flow direction does not conflict with existing fans in the TV. Ideally an exhaust fan (blowing the hot air out of the TV) would be best however in my case, on the 50 inch where I was installing, I couldn't exhaust air due to another fan close by pulling air in. With that said, I installed the fan to pull air in. On the 50 inch, there is a perfect spot just inside the lamp door (to the left) for a case fan. Its a perfect sized square that the fan will fit in to and doesnt require any screws to keep it in place. However if needed, drill some holes in the TV case and use case fan screws to attach. Some common sense and creativity here is all you need. This sounds long and complicated but just use your head. If you have built PCs you should understand voltage requirements, wire polarity, etc. and shouldnt have an issue.

Once installed, plug the USB connection in to the TV, replace lamp or case covers and power on the TV. The fan should come on when the TV is on and should go off when the TV is powered off and the TV is cooled down.

I only have 1 USB port on my TV but if I had more I would install more fans this way. You could also use a 12v DC wall adapter to do this however the fan(s) wouldnt cut off when the TV cuts off.

Both of these suggestions cost me $0.00 and fixed my issue. My lamp was replaced mid last year and my picture looks great. Hope this helps.

Hi everyone, my sammy SP50L7HX just got plagued by the damn auto shut down...

I opened the lamp door and searched fot the blue switch but I can't see any switch???

EDIT: It seems the blue lever is gone??? Maybe it fell into the interior of the TV? How can I do without the blue lever? How can I psush the switch down??

Cut the wires and twist them together. Install a wire nut and/or some electrical tape. :banana:

I tried several searches to see if others have had the same problem as me and wasn't able to find any threads on point.

So, I have a Samsung HL-P5063W that I have owned for about 3 years and over the last several months it has developed a problem of just turning itself off. It can happen several times in an hour. After it turns itself off, I can usually turn it on again via the remote and may be good for an hour or longer, or it may turn off again in a few minutes. The problem seems to be getting worse lately and seems, oddly, more prevalent during the daytime than in the evening.

Anyone know what's the matter?

I suspect it may be the lamp or another part needs replacing (light engine maybe?), but really don't know. I'd like to determine the problem before I contact Best Buy where I bought it or Samsung (I don't have a lot of faith they will know the problem and just want to start replacing parts until it works again...).

Any thoughts greatly appreciated. TIA.
After 3-4 years of age, DLP TVs may have some problems, however the most common, the most possible problem, is the lamp. However, some of the Samsung DLP TVs have either round or square lamps, so before you will try order a new lamp , see the part number (normally oh the side of the TV) and see what the shape of the lamp is.

so ive read this thread and done a bunch of google searches and I haven't been able to fix my problem everyone else here seems to have.

I have a Samsung hls5088 dlp. a couple years ago the tv started to turn itself off randomly. it got progressively worse and i kind of gave up on it. now im back to trying to figure it out again

now the tv is on a 15 minute cycle. it will turn on and turn off at after 15 minutes. i did 4 times with the same result at the 15 minute mark it turns off.

so far ive pulled the tv away from the wall. taped the switch door down, vacuum the vents.

when the tv turns off there is no clicking or buzzing noise or anything. just turns off like normal. there is also no flashing lights to indicate anything.

so anyone have any other ideas or what i could looking into to fix this tv

thanks

HI! After 3 years you may expect lamp need to be replaced. Part number is on the side of the tv, or it may be called as a "lamp code" _ BP96-xxxxx. Problems with light engine normally happened after 5-6 years.
