Jamma bootleg Galaga pcb in Galaga cabinet all of a sudden stopped booting at all. Traced 5v which was now missing at the board. With the edge connector unplugged from the pcb I get the proper 5v but immediately upon connecting it the 5v disappears. The edge connector plugged into the jamma adapter with no pcb gives me 5v reading but not when adapter is connected to pcb. Same thing happens without the jamma adapter when I try plugging the edge connector directly into the original pcb. The cabinet has a switching power supply + adapter as well.
