ive recently taken back a panasonic tx28ps12 to comet due to the band in the picture problem. Comets engineer didnt know what the problem was just said it was a digital processing fault. So i exchanged after a lot of phone calls and angry me to a sony kv29fx68 great tv no picture blooming or bands in picture. Now a new problem the sony has a mark ie a dot like a dead pixel bang in the middle of the screen so back to COMET!!!!!!!!
