Blue screen of Death?
No, this is not windoze.
can you change channels?
a blue screen usually means that you don't have a signal.
Is it hooked up through dvd/vcr player?
Try a straight connection to cable or antenna.
If it remains, then it requires surgery.

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.

I have exactly the same problem with the same model tv. I am currently scouring the internet to try and find a solution to fix this problem. If you find one before I do, please share your findings and I will do the same. It has been suggested that it could be capacitor failures in the power supply unit. I have not looked at the psu yet to see if any capacitors are "bulging" I want to be sure before I start changing components.

Hmmmm.... most likely cause is a power supply failure.
They do occur suddenly, since electronic components are at most stress upon switch-on.
