G07 random blurriness after recap & new flyback

I recapped and put a new flyback on a G07 in pretty sweet condition. I was pretty stoked on this monitor and getting it back to close to new shape. But a week later it's randomly going fully blurry and I can see it snap right back into sharp focus.

Bad repro flyback (got it from Bob Roberts)? Cold solder joints on the flyback? Something else I should be looking at?

Thanks for any input or advice!
 
1) Check the wiring to the back of the focus pot.

2) Check that the focus pin is in the socket good and not bent or broken.

3) Check the focus wire to the socket to make sure it is connected good.

4) Check the socket pins for cold solder.

5) Check the neckboard and chassis (especially around the flyback) for hairline cracks...
