I've got a 5 year old, direct view, Mitsu 36" TV and the screen all-of-a-sudden turned yellow. For instance, where there should be white, it's yellow. If it should be red, it's red w/ yellow tint. My whole room now has a yellow hue to it and it's making me ill. Does anyone have a clue what went wrong w/ this? It may be a blessing, as I have my eye on a Sony 36" XBR. If it's just a tube or cheap fix I might just get it fixed....thanks!
