LG 37 INCH LCD TV BLINKS 3 GREEN THEN 1 RED THEN TURNS OFF SOMETIMES WHEN YOU TRY TURNING IT ON, WHEN IT TURNS OFF THERE IS NOW LIGHT ON AT ALL ON THE STANDBY INDICATOR. IT GOES BACK ON WHEN YOU TAKE THE PLUG OUT FOR BETWEEN 5 MINS TO 30 MINS. DON'T KNOW IF IT IS A COINCIDENCE BUT IT STARTED WHEN WE INSTALLED A WII CONSOLE. PLEASE HELP AND FORGIVE MY CAPITAL LETTERS AS IT IS TO DO WITH SLOW TYPING. THANKS, BRYAN.
Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

It would be the best to measure the voltages on the power suply 12V 24Vand all low voltages, then check for the bouiler capacitors in secondary. If everything is ok then check the inverter on voltage, If everything ok then the inverter board is defective
I have an LG 37LF65 ZC AEC which I've had for less than 18 months. The Green light flashs three times then you get sound but no product. We did get No Signal showing for a while but now no product (picture). LG are no help.

I have exactly the same problem after having owned the tv for one day, does anyone if there is a simple cause for this?
