Help - No picture in Cabinet - unknown wire disconnected
Hi people,
I am trying to get a jamma cabinet up and running with mame...The eventual plan is to put jrok's board into it but first I am trying to get it running....The cabinet worked before it went into storage but now after several years, I am not getting an image at all...I believe the monitor is getting power because it makes that quiet sound when I disconnect power from the cabinet....the sound is hard to describe but it common to all crt...
Enclosed is a picture of a wire that had one end hanging loose in the cabinet and whose purpose is unknown to me....I suspect it may be some kind of ground but I am hoping one of the more seasoned members can help me identify it...The way the wire is soldered in leads me to believe its was added by one of the cabinets previous owners as it likely did not come this way from the factory.
The wire in question is the one that is nearest the flashlight....One end of the unknown wire is soldered into the middle of another wire which runs the around the back of the monitor....The unknown wire has a connector on the end of it but I do not see where it could plug in...
Could this unknown wire be a secondary ground wire causing my lack of image whatsover? I disconnected the jpac to see if I got any image (making the assumption that the neo geo cabinet would have some image even without a cartridge) but alas, no luck....
I would be very grateful for any advice...
thanks very much.
