I had the same problem with my Hitachi PJTX100. I discovered that there was considerable dust build-up inside the unit, causing insufficient venting of heat which then damaged the color prism/filter. It was close enough in time to the warranty for Hitachi to cover parts replacement (approximately $1,600). Since the repair, the blue patch is gone. I also regularly vacuum not only the outer cover but also the inner air filter that easily snaps on and off.

most likely you have a bad buffer, if the redish area runs left to right take a ruler or something and see if its the bottom side or the top and pull that board, when u have the back off it will be on the left side connected to the y-sus, go on ebay there is a few people who sell them

VIZIO P42hd PS42a plasma Picture has two vertical lines (one red/orange, one blue) going down the right-hand side of the screen. Lines are clearly visible


The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.
