Lisa 2 Video Problem

Has anyone ever repaired a Lisa 2 with the following symptoms: A distorted video image on the upper 1/3 of the screen? I'm the high bidder on a Lisa 2 on ebay url: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2013387255&r=0&a… If you look at the screen shots, the video screen is distorted very similar to what my compact macs do with cold solder joints on the analog board. I figure that it's either a similar problem, dirty contacts or bad caps on the board. Just wondering if anyone has seen similar symptoms. I think I can get a Lisa video board from a friend in DFW who has a cache of Lisa's in storage. The guy's Apple collection is awesome. He has several of absolutely every product Apple ever made including a lot of prototype stuff that was never publicly released. I usually don't attempt board level repair, but for a Lisa, I'll make an exception. I thought Tony might have done one before. Have you ever seen this one before Tony? I think a Lisa would fit in perfectly with my NeXT's, Sun's, Indy and BeBox. Thanks, James You mean you're supposed to read the manual first?
