i would try the abvious first, unplugg the tv from the ac outlet and wait for a few seconds then try turning tv on see if the problem is solved, if not it might be that the key board panel needs replacing.

You may have a case of a bad signal board. The clue was that your power button on the tv and remote are the only ones functioning. If the tv is still under warraty, call the service number to get help!

Did you have any luck? My LG is stuck in demo mode too. Menu button doesn't work, and keylock was on as default so I can't use the buttons on the TV itself.

check the invertor boards resistors they power the back lights
also check for any capactors that have blown (raised tops) they look little bateries
