My Mitsubishi VS-60621 (12 years old) 60 inch rear projection TV seems to have a convergence problem that just started yesterday. The red and blue won't line up manually (the blue won't move at all) with the remote and the picture is ghostlike with the colors being very bright. Can I fix this myself? I was told that it may be the ICs. Whatever those are. Thank you.
