Hi guys, got my first pin and it's a Flight 2000. The cabinet is in rough shape. I have this doubt about the type of wood used in the backbox. Could it be MDF? It looks like MDF around the backbox, the bezel, not sure if it's called bezel.
Another thing is that the pinball plays mostly fine except for this issue that appears about 30 minutes after turned on.
The game starts to score by itself, in 1000 points increments. This only happens when the machine is warm.
When this problem shows up I put the machine in Test Mode and it shows switch 17 closed, which is the "B" letter. Also the top right drop target shows as if it were switch 17 too. I've cleaned and adjusted the switch with no luck.
Could this be a switch matrix issue?
Upon looking at the matrix both of those switches are next to each other in the same row.
I've replace both diodes with 1N4007, but the problem is still there.
I'm trying to learn how the switch matrix works.
