More progress. I found an open 270K resistor in the RGB screen control circuit. Now that I think about it, I replaced that same resistor is a 10" GE many years ago. Probably a common problem. Someone had the vertical size and centering controls out of adjustment and that is now fixed. The main problem now is the bad focus divider. I can bring the focus in; but, it drifts after it warms up and must be adjusted again. I can also hear HV hissing from the focus divider. It appears to be a common value (240 meg, tap at 40 meg). Maybe I can find one without too much trouble. The GE part number is EP14X173.
