Motorola Quasar Vertical Issue

[mcmlxv]

OK. FINALLY completed the suggested recap with the CDE DMEs, and sure enough, the vertical is stable. Recapped the convergence board as well. Thank you Doug! Your advice was spot on. The picture has been good for the last couple of weeks.

New problems have appeared now. The picture pulls diagonally and shakes all over the place. I guess one would refer to this as horizontal judder? I turned the set on yesterday to capture and post a screen shot, but the set won't produce a raster now. There is power. Audio is present, and the CRT neck is glowing.

I removed all the boards and cleaned the connectors and mounting pins with Deoxit. I also have inspected the works for any loose connections and suspect wiring. Still no raster.

I'm unsure of my next step. I have tackled radios and simple B&W TVs with success, but never anything SS, and certainly nothing like the Quasar.

I am committed to returning this set to correct operating condition, as I feel it's very much worth the effort and the learning experience.
