My hook pinball seems to have a LOT of odd problems that i have heard could be caused by the switch matrix but im not sure so i am asking for help on this.Whenever i flip the right flipper,it triggers the right outlane. Whenever i flip the left flipper,it triggers the left outlane and fires the kickback.It also wont let me do a skill shot because as soon as the ball gets into the plunger it says i missed the shot before i fire it.The Left Ramp is awarding a score every time i hit the wire gate and it activates clock shop mode so every time i hit the ramp it scores 4 times.There is also other random coils i hear firing but cant tell which one it is.Both left and right slingshots fire off even if the ball only hits one.I have heard that it could be a switch matrix problem called "phantom switch closure" or shorted switch.I have tested the switches manually and flipping the flippers seems to fire off other switches even after adjusting them.I dont know how to test switches for bad diode.I have not tested if its on the playfield or cpu board yet.I heard that changing transistors Q55-Q48 and resistor RA6 could fix it but i don't wont to hack on the board until i know for sure .Any help would be much appreciated.
