I'm looking at a friends DE Star wars and the trough eject coil continuously fires when powered on. He found that the coil leads had melted/broken off and so he ordered a replacement coil and powered it on. Same problem. A fuse blew and was replaced and then he swapped the coil wires and turned it back on (yikes).
So, when I checked, i found Q45 was bad which is consistent with the manual. I replaced Q45 and then fired the game up but the trough eject coil still continuously fires. I re-tested Q45 and it needed to be replaced again.
So, my question is what other components on the pcb's should I be testing/replacing. Looking at the schematic, I see the other components that are on the PPB related to this are D2, D10 and R2. Isn't there another transistor on the PPB I should be looking at. Is there a pre-driver transistor? Any other components to check on the CPU pcb?
I've been looking at the following manual on page 33 of the pdf (Page 29 of the actual manual)
I measured the coil and it tests fine and also replaced the diode on the coil.
I am not that familiar with DE games and so any help is much appreciated.
