Ok, I'm a bit befuddled. This monitor has had a cap kit and new flyback, and was working fine for some time, but now it's having issues. There is no deflection upward from center, and about 2" worth down from center. FR401 checks out good, the two 2SD1138 transistors test good, and I've replaced IC501 with absolutely no effect. I suppose the pots could be bad, I'm going to check them. Anybody got other suggestions?
 
I assume you've gone over all the 400's for cold solder joints, and inspected the yoke connector area for cracks?
 
I did reflow the yoke connector, and checked continuity along the traces leading to it. I haven't been over the rest of the 400s yet, I'll check them all out next.
