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
