I am a bit stuck on fixing my 20ez. It will not lock down on the vertical (DK rolling side to side). I just finished a cap kit from Bob Roberts. I did not replace the Fly or Hot. In the manual it talks about looking at D161 if it does not lock down. So I checked diode 161 and it checks out fine. The pot for the vertical hold does help and you can lock it down for a bit. But, once you turn it off and on again it starts to roll again. I also checked the B+ and it is good.

Any suggestions on what to try next?

Thanks for the help.

There's a pot almost dead center of the monitors pcb. Use that to fine tune. That'll "lock" it down
 
I second that Dokert. I just had the same problem with my DKJR Cocktail. The vertical position pot on the DKJR game board was bad. I replaced it and it was fixed.
