All of a sudden the "standard" mode which is calibrated to 1080i and the "movie" mode which is calibrated to 480p have a greenish tint to them. When switching to other modes (ie watching 1080 in "movie" mode or 480p in "standard" mode) the tint seems to be gone! So i don't believe its a problem with the crt guns, but what could have caused this to happen?? How can i fix it? I know how to get into the service mode so I can hopefully fix it myself. Btw i never touched the cables and i double checked them and all seem to be good, i have 2 different sets of cables hooked to 2 different inputs and they both exhibit the problem. And i havent played with the service menu for a while so i know i didn't change any settings.
