Ok thanks I'm going to do that!!

Hi, my son TV is a SAMSUNG LN40B750U1FXZA (PICTURE 1), is not turning ON.

He said the night before was working perfect, he just turn off and the next day is not working anymore.

I start reading some threads; learning terminology and some tips to find the problem and this is what I find...

The only signal of life is the steady red light in front (PICTURE 3), this means some board still working. I touch the power up sensor next to the red light, nothing happened but if I tray turning on with the remote control the red light GOES OFF and nothing happened. NO...
