Are you sure that all plugs are where plugged in where they should be.
Check carefully thhat the scart plugs are in the right places.
good luck

The time taken to show picture is due to leakage of electrolytic capacitors in the internal power supply of the set,if you are technical person check and replace the capacitors in the secondary stage of power supply,ti will suerly solve the problem.

bad reception of you picture, try to plug well you tv in put cable to make you picture clear. other wise change a place where you have plugged power cable on wall, there also may be sparks from the switch socket on wall causing troubles

main board problem

This model has PiP (Picture In Picture), find the button on the remote or check manual, this mode is most likely turned on and is being shared with one of the AV channels, or try turning on a plugged in SCART device to see if this picture shows on the other half of screen.

I wish I had an answer for you but I'm in the same boat. I've got a 42pc5d and it's doing the same thing. I'll turn it on using either the remote or the power button on the unit itself. The LED will blink either two or three times, then shut itself off. I tried plugging the unit into a different outlet. I tried unhooking all inputs (PS3, DVD player, antenna, etc). The tv was still shutting itself off. I called tech support and the lady who answered asked me if there was a power button on the unit. Well, of course I understand LG has hundreds of models but I felt like I was dealing with someone who didn't care enough to even open the manual to see for herself. Anyway, after a "reset", the TV is now nothing more than a very expensive paperweight. To say I'm displeased is an understatement.
