SOURCE: lg lcd tv screen goes
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.

Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.

Maybe!! It depends on where the audio sys failed. If it failed at the output drive, then you can take the audio off at the audio output jack and input it to your stereo system where there is an audio input. You'll need a cable with RCA jacks on it for this.
If your system is muted for some reason, this may not work.
