You should first turn off all the color on the set, or play a b&w Tape or dvd. What were looking for here is, what the color balance or grey scale looks like first. If a B&w video or whatever looks true to grey and black and white then you have whats called croma problem in the color or video demodulator. My friend I wish there was an easy way to assist you in this type of repair but theres not, as it could be a problem in the video/croma demod section of the video jungle IC and this is not a user serviceable part or repair as thers several issues concerning Hi voltage as well as x ray radiation. Now if its a problem where the grey scale or the B&W is not true to color then theres a problem in the R G B driver circuits. Could be a simple drive adjustment or even a soft or weak picture tube. I hope if your not a tech you seek a pro to assist you in this troubleshooting as this could be dangerous for you as there are no user serviceable parts inside this set. Good Luck

The old saying that a pictures is worth a thousand words could have been looking at this one... If the lower screen had been streaked in B&W or bands ran completely through the picture Old Drummer I would suspect the logic board also but that's lower y-board failure.

It sounds like the video output isn't
working its most likely a component
failure 1 thing you could try is connecting
a rca cables from video/audio out on the set to
another set vid/audio inputs to see if it the video gets
through.This is a problem that requires technical
knowledge and test equipment to trace the video

If the adjustments on the power board are correct and if you are not at high altitude, the plasma display panel is defective. If the set is off warranty, it is not cost effective to replace the display panel. If it is off warranty, you should give the manufacturers Customer Relations a call. The phone number is usually right on the back of the tv. The manufacturer of the tv might make a warranty concession if they are concerned about their brand reputation. Some manufacturers find it less expensive to just switch brand names rather than make good on defective products. If all else fails, you might get some money back by selling the circuit boards on eBay.

I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.
