I can't figure out my problem and need some help!
I have a black knight 2000 I'm working on for a buddy that when I got the knocker just stayed on and the machine didn't boot and just hummed really loud.
I rebuilt the power supply board and it turned back on! After shopping and fixing all the other little things I CANNOT figure out this matrix problem.
Every lamp after #33 lights itself and 3 others.
-Checked pretty much every diode.
-Replaced #33 diode.
-Unplugged the wheel board to test (didn't change)
-Unplugged bonus 2x-5x board (didn't change)
-No battery corrosion
Here is a video of what I have going on
By the way the "m" in ransom works fine I just never had it all the way light in the game.
