Tv was doing great for awhile, no problems at all. Then all of a sudden I noticed something was very wrong. After throwing in Avia, it turns out my blues are now green. Checking the grayscale revealed nothing. Looked perfect. Only when looking at the color bars (and when watching movies etc..) did I notice the problem. The blue bar looked just like the green bar. I'm competent in the service menu and have fixed problems on my tv before. I don't have any equipment like a color decoder or anything like that. Anybody have any advice, or have seen this happen before? Help!!!!
