Picked up "working" PP (if only I had a dollar for every time someone said its a working arcade! lol). It's a Nighthawk system v9.11 in an old Fore cab, and of course it did not start up on first attempt. Troubleshot and found a bad mobo, so I replaced it with same model Intel DG41TY, got it to boot, and receives all GREEN OKs throughout bootup, and eventually gets to the Insert Coin screen. But I am receiving error messages like "Coin 1 is stuck or wiring is incorrect" and none of the buttons on the CP react, nor do any of the service area buttons. I've already disconnected the wires from the microswitches to rule out bad switches. Other times I get the same message about a bad Coin 2, and one time it listed bad Vol Up, down, Test, service switches all bad, but realized the square 4 pin power connector was disconnected from the IO board. Plugged it back in and the Vol/Service button messages went away, but still do not work. Inspected and double checked everything, but cannot get the game to start - even though it is set for FreePlay. During boot, it does identify the CID, IO, and the mobo match, and harness looks clean and in good shape, and I have 3 green lights on the IO board. But with the butons not working, and error messages, does this indicate my IO board is junk?
