I bought a nice mitsubishi HD TV in 2002 and it worked fine. the past year or so though it's convergence will change itself drasticly and give me a picture where i can basically see 3 of everything, red, blue, and green. To stop this I've just left it on all the time with a black screen becuse it would mess up after being turned on, but i'm afraid it's causing more damage. Now when I change my reciever that sudden flash of the picture seems to be enough to mess up the screen. It's so bad I must let the tv sit for up to half an hour and cool down before it will even let me change the convergence. My only understanding is that the red and blue tubes and misaligning themselves and still considering themselves to be at factory default, but I would like to know wether this is a problem I can fix or if I need to send it in for repair? This has bugged me for the last time and I want it fixed as soon as possible!
