I have a World Class Bowling PCB on a Wells Gardner 25K7000 that only displays video on the right side of the screen.
All I did was change the backup battery as the settings wouldn't save.
Tried another known working Jamma PCB and the monitor is fine.
Tried setting the PCBs dipswitches to the correct settings also.

Has to be some kind of dip switch settings. Unless you bumped the monitor and a wire came lose somewhere. But I'd mess with all the video settings first on the game board. Just fyi if the battery is easy to access you can hot swap it next time (while the game is turned on). Then you won't lose your settings. Obviously be careful not to short something out but it may be easier then dealing with this.
 
The settings were already gone as the battery died.
Looks like I have a game board issue.
I tried one of those multi boards for the heck of it. So it's not a monitor issue.
***Definitely a PCB issue. I tried to play a game and when you move the trackball the back flick left and right quick and the ball goes in the gutter. No matter how slow and straight you try to roll it.

I guess I need this moved to the technical- videogames- general repair and help section.
