LG TV Button will not turn on tv, Remotes won't either. Have checked power supply and it's ok.


Have you unplugged the tv then plugged it back in--this will usually turn the tv on----have you had a power failure---brown out---power disruption of some sorts---if so unplug the tv for 24 to 48 hrs---this gives the tv a chance to reset---ck with your manual for situations of power problems as it may have instructions for this---all of this is based on that the batteries are good in remote.

TV powers on and and there is a backlight but no picture. The power supply board has been replaced but I haver no LG power up and drop down menus... Bad Control Board? My house was hit by lighteni


Hi, checking user manual there's no soft reset option so maybe the main board is faulty too, usually when there's a damage by lighting in power supply this also reaches the main board since they aren't electrically isolated.

My lg tv wont turn on.


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.
