I have a 50 HItachi Plasma tv, after awhile the picture goes black but the sound is ok. It won't come back on until we unplug the tv then plug it back up. Sometimes the tv will stay on for an hour sometimes 15 minutes. Its random how long the picture stays on. Any ideas?

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

MY TV KEPT GETTING WORSE EACH DAY ALSO. BUY A CAN OF SPRAY AIR WITH THE EXTENSION SPRAY TUBE. WHEN YOU GET THE TV RUNNING SPRAY THROUGH THE HOLES IN THE BACK RIGHT ONTO THE FAN BLADES OF BOTH FANS. THE DUST WILL FLY OFF THE BLADES. A VACUMM HOSE WILL HELP PULL OUT THE DUST. ALSO SRAY THE POWER SUPPLY BOARD FOR DUST. I APPEARS THE FANS SLOW DOWN WITH DIRT ON THEM AND THE EXTRA HEAT BUILD UP JUST AFTER THE TV IS SHUT DOWN IS CAUSING THE POWER SUPPLY TO BE IN A SHUT DOWN MODE WHEN POWERED UP THE NEXT TIME. BEEN TWO WEEKS NOW AND WORKS PERFECTLY NOW AGAIN.

This is not a digital artifact, set-up, or adjustment problem, this is a television in need of repair.
