Question about Flat Panel Televisions
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.

This problem is caused by one of thee problems.
1) The inverter board(s) is bad.
2) Power to the inverter board(s) is off.
3) The CCFT(cold cathode fluoresent light) is bad.
Since the picture flashes for a second you may also check for loose connections for the above items.
Here is a simple test you may also try. With the TV on take a bright flashlight and press it against the screen. Look for an image around the edge of the flashlight. This will verify that an image is being sent to the screen.
