Question about Sony FWD50PX2/S 50 in. Plasma Television
Hello... i just bought this tv on ebay about a month ago. i turned it on one afternoon, and it was on for less than 10 minutes before a very loud, almost glass breaking sound happened and my picture disappeared. the sound still works, but no picture. tried turning it off and on....disconnecting power and such. i have been reading many reviews from others with this same model, and it isnt a rare happening...there are several instances of the exact same thing happening particularly in this model. seen as the tv is new to me, im kinda freakin out. due to how many people have had this same experiance, i was hoping someone could tell me what the problem was, and what needed to be fixed or replaced??? i dont have a warranty, and want to get it fixed ASAP and would appreciate any information.
There is no back light in this tv sony it is a PLASMA screen

Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If you open up the TV, you may find a bad part stick out like a sore thumb.
If you have some electronic experience, you can purchase a Service Manual over the internet and 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.
I hope I shed some light on the subject for you.
