My 5 yr old 47in Panasonic Rear projection has got an attack of the alien green skin tones.This has been on going problem for the last 18 mths, but only for very short periods. Lately these have got longer (room is cooler with our winter kicking in?). I guess its a red gun problem. Funny thing it only does it on TV and never with a DVD.
Any clues out there?????

The lamp may be bad or a fan has stopped running. Remove your lamp and see if it's shattered or dark and gray in the center. Also your lamp timer could have reached it's limit. check your manual to see how you can reset the timer only if the lamp looks clear.
try unplugging the circuit board thats connected to the green picture tube thats the board in the middle then while the boards unplugged try to power up the tv if it works it means your green picture tube is shorted
Usually what I find in a case like that is that there is a loose solder joint on the CRT board of the red picture tube. When the connection is good the picture looks fine but when it lets go the picture turns that awful greenish-blue. On most sets the bottom front of the TV will disassemble to allow access to the CRT boards, and the solder joints can be resoldered quite easily. If you do not have experience resoldering boards in a projection TV then allow a qualified tech to handle it for you.
