Default KDS Rad-7bk LCD Monitor Distortion

This 2004 LCD monitor is nearly working. The onscreen menu is
functional, clear, and sharp.

But the computer image is distorted. It's like every other scan line is
moving back and forth at something like a 30 to 60 Hz rate. Auto-tune
does not affect the problem. Again, the onscreen menu is clear and
sharp while the image behind it has this interlaced distortion.

There were two bulging electrolytics , 470uF@16V) on the
control board. Replacing them made no noticeable difference. There are
plenty of smaller electrolytics, but none obviously bad.

There's one online reference to the problem, but no useful solution:

Any suggestions? Thanks!
