Mk6 Pompeii showed logic door open error. I changed the battery on the I/O board. When it booted up next, several of the buttons didn't work. After removing both the logic and I/O boards and reinstalling them, it was difficult to get the No Signal display to go away. I pushed the boards in harder, and now it boots to the play screen, but has errors. It says Watchdog Reset and BACC Signature Mismatch. Also play buttons 1-2, 1-3 1-5 and bet button 2 are the only ones working. I can't get into the diagnostic or test menus because the buttons aren't working. Will a ram clear fix this or do I have other issues?
