I have an older monitor from a video game - and it has a jitter on the horizontal lines on the screen (vertical is locked), yet I don't see this jitter on the H Sync. Using a signal generator (Cross-Hatch, Dot, etc.) and all outputs are the same. Game source also shows same jitter on same screen.
It is not the WICO monitor signal generator as other B&W monitors show a locked image.
Schematics here:
Monitor has been recapped. Horizontal does lock, but jitter still present.
Suggestions appreciated!
Thanks,
