Back to this monitor after several weeks layoff. Picture collapsed to a thin horizontal line. Unsoldered and tested the usual suspect resistors I was told about in my last post on this monitor. All tested OK, cleaned pads and reinstalled. Replaced the 9800 ohm resistor which tested 5200 ohms. Thought that had to be it, but no such luck. Cap kit is fairly new, so doubtful if that is a problem. So, what next? Bad IC maybe? If so, which one? Thanks.
