I am using a wg k7000 monitor and I have a slight jump. I have tried to adjust the pots with no positive results. Any one have any suggestions?

more information would be helpful. eg. what are you using the monitor for/what are you inputting into it. is there a way you can test to see if the jumping occurs regardless of what is being input? (this helps determine whether the problem relates to the monitor itself, or if the signal being input is your problem).

I am using it with a JAMMA harness for arcade games. I have tried two different pcb's I get the same slight jumping with both

So i have made a video of the problem. I have tested it with 2 jamma boards but now I have a vga to cga converter hooked up and it still does the same thing.  I did a cap kit on the board with no change.  Here is the link for the video.

At the times it looks fine.....give it a whack......does it shake right away?

Possibly cold solder joint?

I give the frame a good rap with my knuckles and it does not jump.
