The problem for 7 blinks is an Interface board. Had mine fixed yesterday. Apparently there is a glitch in the interface board that sends signals to the television. Basically the glitch shorts out the board and the t.v wont turn on and you will see the power light blink 7 times pause then 7 more. They replaced the board with a new one and updated the software on the new interface board. It works like new and i couldn't be happier to be watching it again. Hope this helps everyone else out.

My TV just did this 2 days before Thanksgiving. I just messed with it and fixed it today. Unplug it from the power source for atleast one hour. Plug it back it. Hold the power button til constantly flashes red and green. Wait at least one minute while it continues to flash. Turn it off. Flip the big power source button on the back to off && then on. Then hit the power button on the side, and it should turn on. Worked for mine. Hope it helps.

turn tv on picture comes up 2to3 seconds later tv blacks out then stand by red light flashes 4 times in a row repeatedly..can not turn on or off when stand by light starts flashing but before tv blacks out you can turn tv on and off repeatedly and picture and sound work.You have to unplug power cord for 30 seconds after stand by light comes on to get tv to turn on.
keep pressing the channel up/down button and the screen will come on it may take a few minutes dont use the switch on the side of tv just use the remote buttons u could try the power button on the remote aswell
same frustrating symptoms on brand new 42inch here! tv just turns itself off sometimes without warning or if changing to certain channels. leaves red light flashing for a while then red light goes away. any attempts with remote gives flashing green liht on tv. manual power off and on restarts tv but auto off again. found while manual power on keep changing channel on remote till stable picture appears. then use remote to shut down tv - solid red light indicates standby mode. then use remote to turn on again... till next time it happens. but what is technical fault??
