G07 will show any signal except Gallag?

[Mauzy]

I recently got some screwiness in my Gallag's WG 19k7201, so I decided to test the boards on my G07. The G07 isn't the greatest specimen with an average start up of about 45 seconds for the faintest of pictures to come up, but once its warmed up it looks great. It is used regularly in my Super Pac cocktail. I tried to plug the Gallag boards into the G07 to make sure Im having a monitor issue not a board issue, and nothing comes up. I can turn off the monitor, plug in the super pac boards and they run perfect. I know the Gallag board is putting out a video signal as I can get a picture on the WG, but its idiotically wavy (it wasnt like that before I moved it across the room, so Ill check joints here soon.) Any ideas why the G07 doesn't like the Gallag signal? Its the only other negative sync monitor I have to test on...
