I was able to do some work and replaced some resistors in the horizontal hold circuit and changed some caps. It improved horizontal hold, but only marginally. Basically the image has a very, very small window of hold, then turns left or right. Also, when I was able to get the image to hold, it was off-center. I am not quite sure what would cause an issue like this. One thing I thought might potentially be causing this problem is, when I measured the resistance of the horizontal hold pot, it seemed to jump around a bit in the middle instead of going from 0 to 50k. Perhaps this is why I have such a small window of hold? Any other thoughts? Thanks for the advice!
