The monitor originally in my Astro City was an MS8 29 FSG. I had the chassis serviced numerous times, but it persistently has a HV shutdown issue, and sometimes doesn't turn on.
I got an MS9 yoke and chassis from a member here a while back and I've finally started swapping.
I pulled off the MS8 chassis, convergence rings, and yoke.
I installed the MS9 yoke. First mistake was I installed it rotated 90 degrees. Picture was rotated and geometry was way off. Pretty interesting results. After rotating the yoke to the proper orientation I had a decent picture but the convergence was bad.
The convergence rings that came with the MS9 yoke do not have a very clear mark as to how they might've originally been set up. I put the rings that were on the tube with the MS8 and the picture is pretty good. I'm not sure if this is the correct approach or not.
I've also got some bad color purity on the left and right side. Degauss doesn't seem to be powerful enough to fix it.
These are my current questions:
1. It's easy to tell if the yoke is correctly rotated, but how do you know if it's "fully seated"? It lined up perfectly with the epoxy that was holding the MS8 yoke, but I'm wondering if I should be adjusting it for anything other than rotation and keystone/trapezoid.
2. When tightening the yoke, I realized I was using a very strong magnetic screwdriver. Could I have screwed up the yoke causing the color impurities I'm seeing?
3. How do you decide the depth on the neck where the convergence rings should be?
4. Should I try to make the rings from the MS9 work or is it ok to use the MS8 rings?
