Red and blue colors go across the screen. picture looks concave.

Greetings joanne7,

The issue you are having could be caused by your television needing the convergence adjusted. During production your televison has the three picture tubes that are converged to form a single image on the screen. Over time these can come out of adjustment.
If you go to this link and check pages 57 and 58, it gives you a very detailed guide on adjusting your convergence. I am aware this model number is slightly different than yours, but I own a 47" Mitsubishi and this is the exact procedure we use to do our convergence so I am confident it is fairly universal.

I hope this helps!

Go Ahead. Use Us.

I have a similar problem. I have tried to fix the convergence via the remote and that has not helped. My three colors are separated and the edge of the picture is bent in toward the center. I am going to try a hard reset but i suspect the convergence IC are fried. Since the set is not HD, I will probably replace it if the hard reset does not work.
