My SD went out the other day. I have a spare board with several missing chips in the junk stash. I popped in the missing chips and tested it out. Works great with the exception of the image is pinched at the top; almost like the perspective was adjusted. Its smaller on top width wise than the bottom. I can take some pics later today if that will help.

Any ideas where I should look first?

Thanks!
 
Could be a problem in the pincushion circuit. I don't recall off hand how the pincushion is done on the SD boards, but it's probably a bad mc1495

There are two that handle the x and y correction. That's where I would start.
 
Was one of the chips you swapped the AVG chip? It could be the problem...
