Gateway GTW-P42M303 42 in. shut down and will not power on. No light on front panel.

TV will not p-ower on at all. The light on the front panel never indicates anything. Yellow, green, purple,... nothing. Help if you can. I have noticed simmilar issues reported all over this page. I get no noise indication, light indication or any such thing. I mean nothing. Like it is plugged into a dead outlet or something. Need help before i go f'ing crazy and put several holes in the damn thing.

OK, 10 times is HV protection (High Voltage) and problem can be in D board and Q8013, Q8014 can be shorted along with R8051 open.
also IC8005 can be damaged.
All above parts on D board.
I would recommend to get related service manual for proper diagnose of problem in TV.
Good luck.

I actually bought the 5 year warranty when we purchased this new and it was still under warranty. Gateway is sending us a brand new TV. No need for me to try to fix this, but thanks to all involved.
