Problem has been resolved: Faulty V-Sync wire
I have a WG k7191 25'' monitor that I'm using for MAME (vga card with using Soft-15KHz). Everything is fine the exception that there is a vertical rolling problem happening which I'm having trouble with. I've done a cap job and replaced the vertical hold pot (it was cracked).
The Vertical Hold pot is HYPER sensitive. If I get the image so that it's stable after a couple minutes of very very slight adjustments, it seems dramatic change in the picture (opening a menu for example) will cause it start rolling again. Once it starts rolling it is consistent and changing back to an image where it used to be stable (closing that menu for example) doesn't not affect the roll.
The monitor IS grounded. Any help would be appreciated.
