A little bit of history first.
Have a g07 that was capped, new HOT, and new flyback last summer. The vertical sync has become very touchy. I replaced both NP caps, and this helped some, but problem still continues. I could mess with the pot and have it stop.

Today the game was moved and same problems. Dialed in the sync and played some games and turned it off. Turned the game back on later in the day, and all I could see was a faint penny size circle off center.

This is new problem for me. Any suggestions?

Forgot to mention that. I did double check the resistors and they were fine.

Check the wires that connect to that back of the focus and screen control pots, as well as the wire that goes from the focus pot to the neck socket. I had one of those break loose once and cause that problem...
 
Thanks, modessitt. I will have to double check that on Tuesday when I have a chance to look at it again.
