Default Samsung DLP 56' shut off by itself

I have a samsung 56' DLP. 2 days ago I was watching TV, after 10 mins. it turned off by itself. I tried turning it on again immediately and it went off again. I let it sit for about 15 mins then turned it back on and no problems. Was it just a malfunction? Anyone have this same problem? I tried looking it up in the manual but there nothing about this problem. I had this TV for about 2 years now, it also hasn't been watched alot about 2-3 hours a day. Is it starting to break?

been having the same problem, took the back off and pulled the whole lamp section out, removed the lamp and blew out the 2 fans with compressed air. plugged up with dust. Put it all back together and hasn't acted up for a couple of days so far. Easy way to check is to run a fan on the back corner which will blow air into the back. If it doesn't turn off, you probably need a good cleaning.

well for this TV's you have to give them cleaning maintenance every 6-8 months just to remove all the dust that gets all over the set that could cause problems with the fans and over heading TV sets,

that could be a issue here, have you replaced the lamp before (how long ago) do you hear any weird sounds coming out of the tv or slit vibrating tv set i think the first thing you should do is give your tv cleaning maintenance it could be the problem if that doesn't work the next step should be the lamp.
this lamp have a life span of 6000-8000 life hours if its still the original one it could be that the lamp is running out of the mercury gas and its giving up already that's why it turns of or it could be the ballast the ballast is the board that powers up the lamp and keeps lamp on that's its only function so if its not sending the right amount of voltage its not able to keep the lamp on but first clean tv set then get lamp you probably need one soon anyway

Howdy,any clicking or like something trying to start up sounds?If you do it could be an issue with the board that powers the lamp, the ballast.Do you hear buzzing,whirling ,vibrating,high pitch sounds?If you do it could be an issue with what's in charge of producing the colors on the tv and that's called the color wheel.Ifr you don't hear anything like that and tv is between 6000-8000 hrs of usage or 2-4 yrs it could be that the lamp needs to be replaced.

Default Samsung DLP TV intermitttently shutting off

I have been reading all over with folks having this issue where your Samsung DLP tv starts shutting off for no apparent reason and then you are able to turn it back on after a little while and seems okay. This happened to me while my TV was under an extended warranty and I placed a service call on this issue. This is what my issue was and I am happy to share it. On the back of the TV there is a service panel that can be opened to service the lamp. When this panel is removed, it shuts down the tv as it has switch just inside. This is a panel interlock switch and when the panel or the back is removed, the switch is no longer closed and the tv will not come on. This switch is known as a "self cleaning" switch and will get dust in it over time. The switch is usually to the right side behind the panel and the switch lever itself is usually blue plastic. If you unplug your tv and then remove this service panel, you should be able to see the switch. Just work this switch in both directions by hand 20 or 30 times. This allows the "self cleaning" of this switch to take place. Put the service panel back in place and power it up. This solved the problem on my TV and it has never happened again. One thing to note is that for a "self cleaning" switch to work, it has to actually be used or switched. After sitting for 5 years in one place and having never been opened this was the answer to my problem with the tv intermittently powering off. Luckily I was under maintenance with the tv and there was no parts nor labor charge. I have been in the electronic industry since 1981 and many times the simple answer is the correct one. If you are having this type of trouble, then give this a try. There is no cost or parts required to try it and it may just solve your problem.

I too, had my 52" Samsung DLP T.V. automatically turn off by itself. This was very frustrating, as it was only three years old and was not used everyday. When I called Samsung they refered me to a local authorized service repair company. Of course it was out of warranty. They wanted $100 just to come out to diagnose the problem. Of course in these bad economic times, I didn't have the money to fix it, so there it sat a big nic nac in my family room. So much for hooking up the sound surround and having friends and family over to enjoy a movie.

Anyhoo, I want to thank, thank, thank all who posted your suggestions that enabled me to get my T.V. up and running again without this problem. So far so good!!

Default 52" dlp samsung

We are having the following problems, any help would be appreciated.
Our picutre freezes, but still has sounds, then it shuts off. When we tried to turn it back on it won't work. We unplug the power cord for awhile and try to turn it on again, it works this time, but we have colored lines all thru the picture, but if you hook a computer to it, that works perfectly and the HDMI port works fine for an X-Box. If we shut the tv down for about an hour and plug in back in, our TV is fine, but that only last about 20 minutes, then the picture freezes and the tv shuts down and its the same thing all over again.

Default samsung tv shut off

I have had my samsung 46" tv for two days and last night it shut itself off twice. Should I return it or is it an easy fix. This is my fifth samsung in as many months. The others made a clicking noise so I upgraded. I guess more money doesn't mean less problems.

Since this is a DLP, that is a rear projection forum (Samsung has not made DLP TV's for a while), your question would be better answered in the appropriate section - http://www.highdefforum.com/direct-view-tube-tvs-37/, specifically for direct view TV's.

In any case I would suggest you exchange your TV for another brand.

Then you would want to post your question in this forum group - http://www.highdefforum.com/flat-panel-tvs-38/ (Sorry my previous link was wrong)

And FYI your TV is a LCD with LED back lighting. And I still suggest you replace it with another brand something preferably with full array or local dimming which Samsung does not currently offer.
