Do you know if i can use an inverter from any LCD tv, or does it have to be specific to that model? I was thinking about taking an inverter from another broken TV.

do a chanel set up through the menu as if it was the first time you plugged it in. there is no signal on a digital tv with out an initial set up.

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.
The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.
My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.
Hope this helps, may not apply to your situation.
