Replaced bulb, still have a problem.

Hello, I have a Phillips HDTV 50".

The model no. 50PL9126D/37

The picture went black and the red light icon came on. There was still sound, but no picture. After turning it off and letting it cool down, I turned it back on and had a picture for about 10 minutes, then it did the same thing.

Warranty had expired just a couple of weeks earlier. :(

I replaced the bulb, however, it still does the same thing.

It blinks out a code - 6 long, 5 short.

I do hear a quiet "zzzzz-zzzzz" sound in the same area where the bulb goes in (just below it) before the picture goes black.

That part # is "EUC 132d P/41".

Does anyone know anything about this problem or that part?

Maybe even where there is somewhere to look up the code?

I tried Googling that part and only a spanish site came up and that person didn't have an answer to their question either.

Thanks in advance, hoping someone can help.

Maybe the power supply for the lamp has a problem.
Check also for over heating caused by dust or fan.

Thanks for your reply, SJ44.

I've cleaned the dust from the fans.... Also, all three fans are running properly, so I don't believe the lamp is overheating.

I also was able to actually see where the buzz (zzzz-zzzz) is coming from. It is either the component that I mentioned above or directly behind it. But without a schematic of this television, I don't know if there is another component behind that one or not.

If anyone knows where I might find one, or has information on that part, that would be great.

I also have heard that this may be the part that is just as expensive as the tv. This is why I've avoided taking it in to be looked at. The nearest repair shop (for this brand) is 90 miles away and they charge $50 for looking at it.

What is that component right underneath the lamp box?

It could be the ballast (powers the lamp like with florescent lamps) that is going/gone on it as a GUESS.

The noise/buzz you hear is likely the color wheel spinning which is pretty normal if you have to get real close to hear it. Otherwise it could be the color wheel that is the problem as a 2nd guess.

I would also call Philips and get to a supervisor to see if they will cover it under warranty since it happened so soon after the warranty. Some companies will do this if you find the right person willing to authorize it.

Good luck & welcome to the forum! :hithere:

Hi, PFC5, is the color wheel housed in the light engine?

The buzz that I hear, only happens once it is running for a few minutes, right after that it shuts down the lamp and the fans continue to run and then I shut the tv off. I can see a dim light that is the zzzz-zzzz noise. Possibly a short?

I'll do some research on a ballast. Maybe I can find a picture of the tv with the back off to help me identify what part I need.

Yes the color wheel is right behind the lamp and between the lamp and the DLP chip. If the color wheel doesn't spin up to full RPMs you will not get a picture also.

Try unplugging your TV for an hour or so and see if this resets something for you. This sometimes works, and sometimes it only works for a short time when it does work, and obviously it sometimes doesn't help at all, but it is free and worth a shot.

Thanks for your reply again.

After researching what a ballast looks like, I've narrowed it down to the ballast. That is the part that is giving a faint light and doing the buzz thing.

The problem I have now is Philips only sells it with the light engine and the lamp....

$1795.00 :eek:

Any suggestions?

It should be criminal that some mfg are doing this since it is NOT actually part of the light engine itself, but they are not the first mfg to pull this type of thing. I would check online sites for a ballast only and save a lot of money. Check the same online stores that sell the lamps for the display as they often sell ballasts also. Check www.partsstore.com (http://www.partsstore.com) as one such place and check others also.

Otherwise I wouldn't pay that much to repair the display you have, since for that money you could get a 50" 1080p plasma, and have a brand new display with a warranty.

Let us know how you make out.

Hope this helps & good luck!

You've been very helpful. Unfortunately, I have checked that site and my model number doesn't have a ballast available yet.

I searched all over the web, until my eyes bled.

So, I'm thinking on buying something new and storing this one and who knows maybe I'll be able to get a ballast for mine in the future.

Before I buy a TV, I'll pick out one I like, then I'll check back to see if it's any good.

Thanks again.

Side note: I had to remove the url from your reply, I'm to new. :D

Good luck & sorry I could find a solution for you.

So Philips wouldn't help you out on the price of repair with the warranty only being just outside of the covered period? I would go up the ladder of supervisor upon supervisor of the supervisor until I got someone who can help and has the authority to cover all or most of the repair costs.

I would remind them that people do not expect to buy new expensive HDTVs every year or people would refuse to buy them, and that it is shameful that Philips does not offer a simple single part and you will call both your state Attorney General office and the U.S. AG as well about this. Of, and do not forget to state that you will be spreading the word on countless HD forums about how horrible they are and how they do not supply parts for the products they sell.

Good luck!

Instead of going to the main dealerships look up TV Repairs in your local area. Most of these guys are members of NESDA and can help you for a fraction of what the big boys charge.

my tv picture went out and the lamp failure light came on- i have ordered a new lamp and it will be in tomorrow- the set , when plugged in- blinks 5 fast and 6 slow on the power button- i have been researching and see that others with the same problem replace the lamp and it does not fix the set- so i have been trying to price a ballast, but no one has one and from what i can tell, philips states that they are no longer aviable for sale- i cant believe this as my tv is only 2 years old- the phillips part # is 996510006793, any ideas if the bulb does not fix my problem as i would think the next poss item to rule out would be the ballast

I have a 50" Hitachi Rear projection HDTV. I replaced the lamp (#UX21513) for the 1st time and now have an 8" yellow spot in the lower left third of the screen. I was very careful about not touching the lamp with my fingers. Any ideas? Thx- Dave

Ok I posted a similar question, I think the problem isn't a new part but rather the bulb life needs to be reset. I was hoping to find out how when I was pointed to this forum.

Only the hours used would be reset, not the bulb life. There is no such setting. Once the bulb ages, it needs to be replaced and resetting something would not magically make it work again..

Well yes I know you can't magically make the bulb new again however if that is the correct term (bulb hours) then yes that is what I am looking for. The bulb isn't burned out or used up the manufacturers sets a time for the unit to stop working so you will have to 1. have it repaired spending money on their parts or 2. Buy a new TV.
There is a way to reset the timer and I suspect that on some units even if you replace the bulb it won't work until you do this.
That is the information I am looking for so I don't have to buy the service manual. BTW some have to be reset by a special remote ( service remote)

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!
