I have a Mitsubishi rear projection TV I bought in '99. As of a few days ago the picture colors started seperating. As you get closer to the top and bottom of the screen the Blue and the Yellow have seperated and curve upwards/downwards. So I don't know what could be the cause. I played with the convergence setting and it does nothing. I'm not looking to repair it myself as I haven't a clue. I was just wondering if it is the picture tubes or some of the electronics that regulate their alignment. Thanks.
