I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.

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

This going to be tough one to figure out, but at least the back light inverter board and power supply are working, unhook it at least 1/2 hour?
You may have bad main logic board problem. Try reading my guide here and see how much the main baord may cost you.
