    My Phillips projection tv does the same thing. It started out shutting itself off once a week or so, but now, it will barely stay on for 1 minute.

    red light flashes and tv turns off.

    My mother bought a Philips 50P8342 used from a neighbor.There were some expected problems, like picture quality, but the TV set up okay. After about an hour it started cutting on and off like the sleep timer was set. (We did not get the remote). I was able to access the menu and deactivated all timers. Well, it seemed ok and I began to watch a show when it started again...........the picture would jump, the sound would go and the tv shuts itself off and the power/standby button begins to flash. If left alone, the tv would turn itself back on for a few minutes and it will go right back off. I went to the Philips website to inquire, but got no response. Upon further research, I found this is a common problem. I like the tv and think it might be worth fixing........if parts can be located. I saw it posted that it may be the power supply or the ssb board. If anyone knows anywhere in northern NJ where parts can be found, please post it ...........thanks

I posted my problem in September. Since then, I ordered the power supply and installed it. I cleaned and reseated all other boards. The TV did the same thing. Discouraged, I ordered the keyboard module. Sears told that part is no longer available. I put keyboard module back in and unplugged the TV. About a week later I turned the TV on and it stayed on until I turned it off. The next day, the same thing. Now I put a DVD player on it and it plays fine. So before you spend alot of money.........try the power supply..it is less than $60.........my TV is a 50P8342 ; PTV 916 I hope this helps....

Contact the company that makes your tv and find out what the "code" (# of times the red light flashes) means. Then call a repair place and check prices on the part. It might be worth having them fix it for you! My tv is a phillips 50" plasma and the light was flashing 6 times witch ment "power board" the part was 318 and the labor was 195....for a tv I paid 2,000 for 23 months ago. I hope it doesnt go out in another 2 years....nice that they know it will go out and even program a "code" in it for you!!!

Got my Panasonic tv back from repair. The repair man mumbled something about some IF IC (Which I take it to be some kind of integrated circuit) which needed replacing. The whole service cost me about 24 Euros, so not a lot considering.

I go through the same thing, the only difference is that when I attempt to turn on my TV, it makes the sound of turning on, then immediately shuts off and the power button flashes red in patterns of 2.

Ex. *Flash* *Flash* 1, 2, *Flash* *Flash*

If there is any information on this problem, please dont hesitate to post.

I have the same problem with my panasonic tv, when I switch it on, the tv stays on for a while, then these horizontal lines start to appear and after a while the TV goes off on its own, with its red light flashing. After a long while it switches back on by itself and whole process is repeated. Time for a new TV I think

Phillips 50P8341 will stay on about 15 mins then shuts off then the power button flashes twice, pauses then flashes twice again...


Seems like it is overheating. Try cooling it down by using a fan to blow air into it (temporary fix). Make sure the TV is well ventilated and heat can escape (permanent solution).

Chances are you will the small signal board. Donot confuse it with the small signal module. You will be replacing a board the size of a playing card. Part# PH3912725871. Follow the instructions that accompany this part. Mainly you will have to adjust the geomtry.

hello dm beatty, First i must ask if you have anything placed on top of the tv? second what i would suggest is for a professional repairman to come and fix it. There are proceedures which you may do it yourself but if you were to mess up it would cost you a new tv. If you would like more assistance to do it yourself place post again and i will be happy to assist.
Please post what you do and how you did it. I look forward to your posts.

Your Red CRT may be on its way out. Try turning down the G2 screen control on the red CRT just a little. That should help for now. A new red tube wil be a reality in the future.

Rear projection


Considering that in both cases, the set will turn on but not stay on, indicates either a condition of overheating due to a failed fan or it could be a component going into thermal runaway in the power supply itself that is causing the fault.

This is not a safe area to probe around in since there are capacitors that may contain a charge for a fairly long time.

If the fan cannot be heard, this is probably a cheap repair, otherwise, get an estimate first.
