Have an AC/DC premium with a flashing orange led on the I/O board at L18
Display error says game will not operate in this country contact your distributor.
No blown fuses, and LED indicates power to all 5, 12, 20 and 50v
Swapped the suspect i/o board into my metallica and error and flashing led follow the board, definitely something with this board.
Metallica's i/o board works in both games
