I've had my APEX GB65HD09W 65'' rear projection HD TV for about 5 years and just started having issues with the convergence on the right hand of the screen. Its still pretty sharp on the left hand side.
I took the cover off thinking one of my bulbs was going out, but all three were lit. I noticed after messing with it that it was working fine again. Then the next day after a while had same issue. I smacked the side of the TV and it was fine again, for a while. I find I have to smack it around 2-3 times per day now.
Any ideas?

Sounds like a solder issue on the Convergence Ics themselves that could be causing the issue.
