I have a System 11 game that was working 100% until a few nights ago. To give a full background, when I picked up this machine it had a hacked and messed up interconnect board. I sent the interconnect to a repair shop (Coin-Op Cauldron), and they fixed the screwed up traces and header pin hacks. The playfield GI didn't work before this, and when I got the fixed interconnect back the lights worked perfectly.
Well, a few nights ago I started having an issue; an issue where the playfield GI sometimes works fine, sometimes it comes on when you power the game, but then goes out after a short time, or doesn't come on at all. I have checked the connectors, the power connectors, etc. The odd thing is that a bank of playfield GI lights located at the top of the pf work 100%. These lights are part of the same connector (J9) the non-working rest are, and will shut off if I unplug the J9 lower playfield GI connector.
Could I have worked something loose when doing other things around the playfield? I don't get why a few of the playfield GI lights would work 100% but not all of them.
Also, is it normal for a game like this to have a low hum when it's turned on? Not loud, but a steady low volume hum? The game does have a proper 3 plug cord, and seems to be grounded properly.
