I've noticed with my Tandy CGA monitor that the picture was going in and out of focus, and would only stabilize once warmed up. Today I turned it on and this was all I could get, no visible signal from the computer, and an occasional crackling sound from the flyback. I took it apart and gently tapped various areas around the main pcb with a plastic tool and it seems like the area near the flyback had the most response, although I was not ever able to see a cohesive image. (The black bar in the center is a camera artifact, and the ones on the top and bottom were because I turned the V-size down)

I have been looking for this model for a while, but they're asking an incredibly optimistic $599, and that has gone down about 300$ in two months from the original price of $899
