After 2 years of use, screen on TV went to white but sounds still works
I have been using my TV with no problems for over 2 years, but one day the picture completely went blank. The channels still change and the volume still works, but the picture for every channel is now a plain white screen.
I have obviously reconnected all the cables to make sure that wasn't the problem, but to no avail. Does anyone have any recommendations as to how to fix this problem?

Plasma TV's have a shelf life. By that I mean the screen is only good for so many hours depending on the model. Most likely, you have burnt out the screen and the set will need to be replaced. The good news is, plasma TV's used to be better than LCD but that is no longer the case. You can get a very high quality LCD TV for a very low price now. Also they use a fraction of the power and don't generate all of the heat of a plasma.I'm sure this is not what you wanted to hear but the reality is that ALL plasma TV's do this eventually, and it is something that most salesmen back in the day didn't bother to tell customers. If you have an extended warranty, you may be able to get it replaced.
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
this is a common problem,the vertical hold has been damaged.dont leave the teli. on,the white line will burn the middle of the screen and leave a black mark. You need a new integrated circuit(i.c.) for vertical hold.
Is the TV connected to cable? Is there a cable box? Is it connected to a satellite box? How is the signal connecting to the TV - the F connector, the red,white,yellow, red,white,,s-video or component RCA jacks? If you can see the onscreen menu then it usually indicates that the TV is working fine and the problem is with the signal into the TV.
