On my Spring Break, there are 8 white flash lamps , located beside the "vacation " lamps that are supposed to fire at ball drain and other times. Mine are not working. I know there is an auxilary lamp driver under neath the pf, have reflowed solder here. these are also driven by a coil solenoid/relay located at the bottom front of playfield. If I activate this manually , the lamps work. I am trying to find out what driver actually controls this relay/coil . I cannot seem to source a wiring schematic. Any thoughts on this problem. I am thinking the driver on the auxilary board ... Thanks..

Thanks for the reply !! I was just able to trace this back to q56 as you mentioned. The driver transistor here was repaired at some point and the legs are broken off flush with the body, there was also a trace repair on the rear which was loose. I need to get another transistor, unless I can find a a schematic which shows an unused one on the board and steal it. I jumpered the legs and grounded them and the lamps fired so everything else is good. Thanks, you were dead on !!

Replaced transistor , and done !! , working well. Onto the next problem, the release ball lamp on the right side, that feeds the flipper is on all the time, need to track down the corresponding transistor as well. Thanks for your help !!
