Hey everyone,
Have a couple of these from a forum member and took a closer look at them. They are labeled SW-2P and are the non-remote control version of the GBS-8118.
First one had no sync, but all colors were there. IC9 switches the sync and had failed.
Second one had no sound and only blue outputs. IC8 switches the video outputs and had failed. The relay closest to the JAMMA edge connector failed and shorted the outputs together on one side. This caused a grounded speaker connection on one board to ground the audio output of another board.
I swapped the relay and a chip off of one to fix the other and am waiting on parts to fix the remaining board.
The chips are PI5V330SQE and are available at Mouser - part # 929-PI5V330SQE. The relays are not available there, but are easily obtained on eBay, only the shipping is slow boat from China. 10 of them plus 5 of the other relay was less than 6 dollar shipped.
