Source for AWSD Sync Selector IC?

Friend tried connecting VGA to his AWSD and killed the sync selector IC. Part number is 312-9X002. I'm guessing it's custom.

Anyone know where to get a replacement or if anyone sells the replacement board that has the part?

i know where to get entire new chassis for those monitors, but no help on just that one part. beginning to wonder if my chassis has the same dead component, mine will output VGA but shows no picture when i try to hook up 15 khz games to it.

Where do you get the chassis from? Does that include the video board? I know almost nothing about arcade monitors.

PM sent holmes.

I had a similar problem with autosync on my AWSD. If you open the main lower compartment, there should be a thin connector called D2. It might be tucked away on the lower edge. If its connected, disconnect it. Boot up and then connect them while the machine is on still. This refreshed me to 31hz after it autoswitched from 15hz. Try at your own risk obviously.
