Title: WG U3100 - picture shifts/flickers vertical
Post by: Carsten Carlos on May 18, 2003, 08:35:58 am

Just moved my cab one room further - the last time I played I notices my monitor (Wells Gardner U3100 -arcade vga monitor) has a little vertical flickering!  :o

Somehow the picture moves/flickers up and down, barely noticable, but still driving me nervous! It flickers only less then a pixel height up and down, but it's definitely there!

Anyone an idea where I could start to look at?  ??? I've all circuits diagrams here -would be easier to find the fault when the picture would be dead instead of this!

I tried other plug-sockets in the house as well, also I turned of the marquee-lights, no changes there. In windows it's still a standard vga-monitor, switching from standard to optimum in the graphics-driver doesn't change anything. I made no changes in my configuration anyway.

Jiggle your V.Hold knob a bit.

Good idea - would love to, but it seems that is has none!  ??? At least it's not in their servicemanual/pdf-file I got here.

Odd. There should be a Vertical Hold knob.
