I turn on the tv it beeps about 10 times no picture then shuts down


the beeping would be due to a failed power supply unit inside or a fuse there-of i would check this out before making costly repairs that will not work in the long run, hook me up with a good rating and have a good day!

My philips 50p8341 beeps then flashes the red led 4 times


4 Blinks means that an incorrect voltage had been detected on the +5V circuit coming from PSU to digital control board.
The PSU must be tested and eventually repaired or replaced.

REAR PROJECTION HDTV ISSUE


Decoding the number of beeps may be possible with the owner's guide but this type of problem is normally due to a failed power supply.
These are often mounted on separate boards located in the bottom of your set and can be identified by the much larger parts you see on the board and possibly its relationship to the AC cord coming in. While these can be repaired, the cost of that will approach the cost of a new assembly.
Unfortunately, modern, more energy-efficient power supplies have some critical components that if bought cheap, don't last very long and frankly, 5 years isn't bad, I read of many dead within the first year.
