I have a black knight here where last week the upper right drop target coil locked on and blew the drive transistors on the board. I have since replaced them and the coil however the coil still doesn't fire to reset the targets, not sure what to do at this point. Please advise if you have any insight. Thanks guys! Clip below of what's going on...

Update...I fixed it. Ended up trying a second transistor and it worked I guess the first one was a new defective one.
On to replacing the power supply caps now.
