I have a Jamma wired cabinet which had a non-working mv1b. I removed the pcb and am attaching a laptop through a J-Pac.
I disconnected the power supply and connected the monitor (hantarex polo) directly to the ac mains (as nothing else needs power since it will be all going through the laptop. However this means that all the ground wires in the cabinet now lead to an inactive power supply which is not turned on (or even connected). Is this a problem? How can I solve it?
