This isn't an easy fix, it sounds like your power supply board is bad or there is a main board problem. I'd suspect a faulty power supply capacitor or heatsink missing, but you have to bring it in to a tech to know for sure.

LG TV KEEPS TURNING OFF


Kindly do not keep attempting to turn it on, as you are likely to spoil some other boards/parts/components of the TV. Look for any loose contacts in power out let, RC jack, cable and socket. In order to ensure, it is not caused by the input device, connect a DVD player
and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

Unlock truflat tv without remote?


ok this totally stressed me out but I figured it out and my TV is ON!! I purchased a really cheap universal remote at a .99 cent store. Sat in front of the TV and followed the directions on the manual for my new remote, keep in mind there was a red light lit on the TV, when all directions on connecting the remote with the TV were complete I pressed on and the TV turned on. I hope this helps!!!!!
