Question about LG DU-42PX12XC 42 in. Plasma HDTV
It does not seem to recongnize that it is plugged in. The power light does not show any more. I had it on a surge protector and all other electronics on the power supply are fine. Is there a way to reset the tv or is there something wrong that is not easily fixed
First, I would try leaving the TV unplugged for an hour so the TV can discharge and reset itself.
If this doesn't work, it maybe something simple like a blown fuses inside the TV that needs replacing.Radio Shack or some electronic store will carry the fuses.
If the other two ideas doesn't solve it, we're talking about a power supply board related problem. I can't actually look at your TV over the internet. But, the most common problem with flat panel TV are the power supply board for the screen itself and the main power supply board for the rest of the TV. Commonly a bad capacitor or transformer will be on the board.
If you have some electronic experience and want to repair it yourself, you can sometimes find a Service Manual for your TV over the internet. Normally, costs less than $20. It will have diagrams, schematics, and part number list for the TV.
