Been working some on a Sanyo 14" monitor in a missile command CT.
Some of the new things I learned may help diagnose this monitor's problems. I'm hoping it's something simple.
The two symptoms are
1) Random rolling vertically. It can be adjusted out but the range of position the vertical POT can be in is infinitely small. And once you get it to sit still, a few minutes later, it will slowly start rolling again in either direction. The longer it stays on, the worse the problem gets.
2) Horizontal width coil doesn't affect the width. I saw something from a Fromm article about changing a capacitor that might help with that - but the coil on this chassis does not appear to adjust at all.
I should also mention the problem with the width is that it's too wide. Just barely - it overscans the edges.
Time's running out since this is *supposed* to be a Christmas gift, but not unless I can get a stable picture. Everything else is working fine.
