I have a P52939 rear projection TV and the picture rolls. I can not figure out how to stop it. I found a manual about rear projection TVs and it said to adust the internal convergence. I can not find it. I opened it up it does not have a board that has the vertical or horizontal controls. What can I do to fix this problem
Vertical sync is an IC function = shop repair = remove light box
and take it to a quality repair facility for an estimate = beware
of "Free Estimates" = pay for diagnosis, get it in writing.Mainly,
I'm finding bad solder connects in this style chassis,sometimes
I work on two or three at a time in my small repair shop........T.
Please rate this solution........................

I have the same problem on my Mitsubishi VS-4571 rear projection TV. About 30-60 minutes after power-on, the unit finally synchs. However, the time required for this "warm-up" has been increasing.
Any suggestions?
