Mike,
I owned a Lisa 2/10 a few years ago with the same problem. What I
found was a bad solder connection on the adjusting pots mounted on the
board that the flyback transformer is on. I resoldered any connection I
could find and on the adjusting pots that fixed the verticle hold
problem.

Subject: Vertical Hold problem
Hello, I have been a lurker on this list for a good while now, picking
up little Lisa pieces of information from time to time. I haven't
posted before because I didn't own a Lisa, although the hunt was
definitely on ! I have been lucky enough to get two Lisa's very
recently. First impression: aren't they big ?! Photographs don't
really convey the size.
One Lisa is missing several parts which I am working on acquiring, the
other Lisa (a 2/10) powers up just fine, however there is a problem with
the screen, looks like the vertical hold has 'gone'. I have never
worked on a Lisa before, but have a dozen or so 68k Macs that I have
restored, so I know my way around old Apple products in general.
Could anyone offer any tips or places to start to address the video
issue ? The display is readable, but is repeated down the screen three
times, with lots of flicker, and a bit of scrolling too.
Many thanks
Mike
