First issue has to do with the two center rollovers in the hoop. When pushed they light up the following letters on the cabinet in Silverball- ERBA. Plus nothing registers when the ball rolls over them. In switch test mode 02 flashes.
Next issues is the B target when pushed makes the arrow under the Center target or N target light flash rapidly along with the left 1000 when lit above the E target. The B will not register when hit.
The A on the right far out lane makes the I, N and 1000 when lit above the A right target flash rapidly. The A will not register when rolled over.
I have check all the switches and diodes all seem fine. All the boards in this game are about a year old from Alltech Systems from what I was told when I got it. Been working great until recently. This is been a bit of a head scratcher.
Now looking for shorted wires or bad connections on the boards.
Thanks in advance for any help guys.
