WG K7000 top of screen sync issue

[b3dr0ck]

I think this is a WG 25" K7000 - I'm not exactly sure yet.  I've got to pull it out of the cab, to see. (I've got 3 other K7000s pulled out - I just want to get one working a 100%)

The color looks good, edge to edge
Contrast good
Brightness good

The issue is the top 2 inches of the screen look out of sync a little, like they are over about an inch.

I've read a post, showing the exact same symptoms - I can't find it now.

What's the diagnosis.

Here's an updated pic of the issue

I ran the cross hatch test, this is the results

Could this post be the one you mentioned?

Yes I believe so.

Is it your belief that adjusting the 50/60 pot and Horiz hold are the solution?

update:

I connected another Jamma to the monitor and it works fine, so I guess something is up with the jamma in the cabinet, maybe there is a setting or something, but

The monitor looks fine, the problem with the screen was with the PCB not the screen itself
