Regarding all the other questions about your scope, I see you are getting a good one to work with. When you have that, you will be able to use one channel/probe to sync the scope to horizontal and the other to look at various points for your problem.

If it is a ground problem, however, you may see the bars change when you hook up the probe ground leads to the chassis or circuit cards, the same as experimenting with clip leads. This could be either exasperating or fun, depending on how you want to think about it!
About now I'm wishing I had a test jig. This poor set has been on it's side and top so I can get to the underside for testing and repair.
