nearly reaches full focus at the end of the flyback's focus pot travel, stops short
I recently bought an untested K7203, and have the problem from the subject line: focus gets better and better as I turn the focus knob on the flyback, but doesn't get fully clear. Everything else adjusts nicely.
I searched the KLOV forums and found a chap (IAML Supporter danpiraino1971) had a similar focus problem. He fixed it by swapping the tube. This tube has a ton of Pac burn anyway, so I didn't need my arm twisted to swap the tube. But after installing a new CRT, the focus problem persists.
I'm re-watching my Randy Fromm monitor repair DVDs today. Halfway though I suspect we're not going to cover this bit o' weirdness, so I'm posting for some advice.
Any suggestions for what I should try?
I have not yet recapped or re-flybacked it.
Quattrohead in the K7000 stickythread suggests a recap might fix this. Although it would be nice to isolate the problem rather than shotgunning, which in my experience hasn't worked out that well.
