Hello,
Today I started working on a Space Duel cocktail project. The cocktail came with only the AR2 and Audio board, I purchased a PCB that was said to the working from a KLOV member.
Before plugging in the PCB I tested the AR2 output voltages and they were all within spec. Both DC and AC, and after replacing the AC cable's broken ground tab, I plugged in the PCB. PCB measured 5.01v at the 5v Test point on the board. This did not waver and held steady.
Now, I don't have a monitor, but if this PCB is good, it should probably be playing blind. Right?
Instead I get a solid light on the board, 2 lights on the start buttons. Normally it will make a few beeps and then lock on to a beep or even an Explosion noise. BUT, just ONCE after about 20 beeps it entered a mode where any button pressed would play a sound.
Would you say I bought a bad board? It does some some evidence of acid damage, but nothing is a dead giveaway with my continuity tests.
