Question about Philips 50P8341 50" Rear Projection Television

1 Answer


Hi my tv comes on for about 10-20 minutes then shuts off. I have to wait awhile to turn it back on but does the same thing again. The first time it happened i waited a couple of days then turned it on and it worked fine for about a week but started doing it again.I tried another plug-in in the house but same thing. House is about 40 years old and hear from girlfriend that shes had the same problem with 2 of her tv's in the last 6 years in this house upstairs and down, could they be related problems with power?.Or something completely different?.

Well based on your story it seems that your tv when get hot loose some of its contact. i beleive the symptom is cause by a loose solder (cold solder). this is normal especially tv's that are aging. it tends to loose its contact because most of the parts/components of this device are becoming hot when being operated. example of this are resistors, transistors, and ic's(integrated circuits). check the power supply circuits and the horizontal deflection circuits. because these two circuits are responsible for problem you are experiencing. also use a magnifying glass in inspecting the board. based on my experience looking alone without this glass is not enough. you need to magnify it, to see it clearly. but if you are not inclined with this kind of job, better bring it to a qualified technician. one more thing, i dont beleive that the house is related with this problem. otherwise all your equipment that are hooked up in it will do the same problem (on and off). i hope this help you! good luck!

Tv comes on for a few minutes then goes off

If you take off the front bottom panel of the tv wich is easy. Then you will see 6 tuning knobs at the bottom middle of the tv .the top 6 control contrast for the lights dont mess with those. the bottom 3 are the power to each is bottom left if your screen went blue it makes sense that the red is starting to go but if you turn down the power to it left 1/8 turn it should fix it for awhile .Its easy.

there is a protection circut that will shut down the tv when it detects a failure in one of the components , when components heat up to much they go into thermal breakdown, the part that is heating up and failing is getting worse , so it will need to be test to determine which one

TV picture goes out

The tv is shutting down because of a power problem. It could be the power transformer or a color gun overheating. Expect at least a couple of hundred dollars to fix it. Some shops will do house calls for around $65 and can diagnose the problem and give you an estimate. Usually they can just remove the board, take it to the shop and repair it, then reinstall it.
