: : This is a shot in the dark, but do you have any unshielded magnets (speakers) near your monitor? They could create the effect you're talking about...

: Thanks for the reply, but no, it has nothing to do with speakers or magnets. In fact, just changing video modes within the AdvanceMame menu screen instantly causes the degausser to kick on. I've been told that a bad or weak posistor can cause the degausser to come on and stay on too long. But when I had the arcade board hooked up, I never even saw the effect, even on powerup. I suspect that the AdvanceMame video drivers send some signal to the monitor that causes the degausser to come on. Very strange. I'll be unplugging the degausser coil soon to see if that fixes it.

Ok... it's definitely NOT the degaussing circuit since I found the wires and pulled the plug from the monitor circuit board. It even says "degauss" on the circuit board, so I'm sure that's it. But the crazy wavy's are still appearing... doh! I've called Wells-Gardner to get a fax of the monitors specifications so I can enter them on AdvanceMame utility. Maybe that'll help...
