Hi


Thanks for using FixYa. Assuming this to be an plasma TV, these kinds of issues in plasmas usually occur after 3-4years.A plasma TV is a very hard working device. From what you have described it seems to be an issue with the power supply board which is the board where all the power cords plugs into.It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. You’ll need to check the power supply board first for any swollen/bulged capacitors. As power supply board is the hardest working board in a plasma TV, it develops voltage to supply all components, high current + high voltage. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

Why is my TV picture dim


Hello David
It sounds that the back light inverter board, and back light CCFL lamps to your TV need to be checked. It will be best to contact any service technician, because to check its back light CCFL lamps, you must disassemble the display panel, a very skilled work indeed. If you are sound in electronics, you can check it. If you wish to know more http://electronicshelponline.blogspot.com/ check this link. It has details. Pull up older posts there by its left side bar, or see it in 'Timeslide' option.

Sanyo 42"Plasma TV DP42746 No Picture


a thousand or so people have experienced this problem! I am a military spouse and our same tv did the same thing on Super Bowl Sunday 2009! We did everything we know to do: call the company, called the repair man, etc. There apparently isn't a solution to this that wouldn't cost more than the tv is worth. So I got an attorney to start a class action:
