hi everyone, i have a old school sony vph1042q, it cast accetable pictures for me for the past few years, but recently it gets unstable, what i means is the covergence moves short after i aligned them, i mean short as in 20 minutes, the red and blue lines just get off to the green lines a very little bit, which affect the quality of the pictures so significantly.
is there anyone here have a clue that i can fix it?
thanks
michael

Most likely an offset on the convergence board due to age, but it could also be power supply capacitors.
