PHILIPS 50 Inch HD DLP Projection TV the picture went out suddenly and there is not sound but a loud humming-buzzing coming from the set...any ideas on what could be wrong or if it can be fixed?


It's the optical block (color wheel) and the same thing happenned to our Philips 50" DLP. From what I've read, it's not worth the trouble & $$ to fix. Dig a hole!

Hello, i have a 50 inch philips flat tv model # 50pf7320a/35. why is the screen half black?


Unfortunately, i have found in my experience is when this problem occours you need to replace the plasma panel, which can be a costly thing to do and takes a little bit of planned time. Other than that you can try to replace the X-sus printed circuit board or the Y-sus printed circuit board. Those two boards control the screen circuitry, Good Luck.

Philips 50 Inch Plasma Model 50PF7320A/37 will not turn on


Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.
