that looks like a board problem, not a monitor problem...there are lot's of guys on here with pretty good working knowledge of this kind of thing...hang in there, i'm sure you'll get a few messages on here to help you
 
Yes, that looks like video RAM.

Flick the small switch on the coin door near the upper hinge to activate the self test. It tests out RAM/ROM and color output and a bunch of stuff.

Dig up the manual from the 'net to describe the self test.
