Ball launch coil sucked on and burnt up. Replaced Q5 D4 and 12 and R4 on the PPB. Turned on with same problem. Question I have is why do the new coils have the diodes on them reversed from the originals? So going by the diode band yellow/violet and violet/yellow on the non banded side even though those positions are reversed on the original coil as the original diode is reversed as well. Turned back on for a split second and coil sucked on. Q43 on the CPU swap? any other suggestions? Thanks!
Forgot to add. After the PPB was re-built with those parts and the same problem I sent the boards out to be checked and repaired. Came back with a note saying to replace the ball launch coil or the boards will be damaged again. Had to since original was toast. Same problem. So am I back to re-building the PPB again and the transistor on the CPU?
