Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.
Check ur power source?Tries tv unplug,replug the tv back about an hour later.By letting tv resetting itself back to factory setting.Now the tv should be working again.If still have same problems,tv mostly have the power supply board problems.Take it back where u bought it exchange for another tv or call LG for a warrenty repair.
I would not keep a new LCD TV that has immediate problems. I would get a refund and purchase a more standard brand television. Experience has taught me that if one has problems immediately with an LCD TV itself, it is likely to continue to be problematic.
Is a tv power glitch,shutdown,start again,tv have no problems,wright?Not a problems,if only happen one?If it happen many times,tv have power supply board problems,take ur tv warrenty repair or return ur tv,where u bought it,get a new tv replacment.
1) Mainboard/Tuner problems - although I'm really only saying this because you guys seem to think its associated with your over the air channels. <br> 2) Power board problems. You power board/inverter may be damaged in some way - blown capacitor or other malfunctions. This is very possible as this could result in the backlight turning off and the screen going black but keeping the keeping the sound. If this is the problem, it will at some time start to happen constantly. Have a pro open it up and look at the power board.
3) The backlight is defective/dying. The backlight is a set of lights that reflects through the LCD panel. If the screen looks black, but you might see a faint picture or you still hear sound, then the backlight is not on. The panel itself could be defective. You can fix it by replacing the whole LCD panel (expensive), replacing the backlight panel itself (need a busted LCD of the same size with a working backlight), or fix the backlight, which is tough and risky.
Most likely its either the power board or backlight. Either way, you need someone to open up the TV and take a look inside. Good luck! Hope it works out.
