OP

Quoted from the4horse:

Hi.
When the ball goes through the first 'F' lane it scores but doesn't register or light the 'F'. You can lane change from other lanes to light it and get the 4 lit for Fire and the multiplier responds as normal. With the 3 power targets, when I hit the middle one it lights the one to its left and scores. The other two, when hit light and score normally. I checked the wiring and switches and changed the diodes but that didn't help. Can anyone shed some light on what's going on?
Thanks in advance.
