If your getting sound, It maybe a loose connections from the Power supply board to the backlight Inverter board. The backlight Inverter board is what supplies power to the screen itself. Or, the controller board for the screen is another thing to look at. It's what puts images on the screen.
If no sound , I would look at the mother board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

If you have some electronic experience, it's best if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15. Cheaper than replacing the whole board.

I hope I shed some light on the subject for you.

I have a 50' plasma model 50mf231D it wont turn on just get a flashing red light on front of tv


That will be a fault with the power supply.
The power supply on these wait for an OK signal from the processor to continue. If there is a fault within the system, there is no OK flag and the power supply shuts down, leaving you with a flashing light.
Check for fuseable links that have failed.

Magnavox 50 plasma Model # 50MF231D dead no power. no lights what so ever. Left unpluged for 2 days and still nothing. Looked at power supply board and no apparent damage to capacitors


Well, if you are going to troubleshoot it, what voltages do you have out of the PS and do you have 5v standby. If your not able to do this then I would take into your local service center.

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.
