Quoted from PINTEC:
Missing solenoid 10 sound:
Reset connector 2J9 test if sound 10 returns.
Attach a ground wire to frame or negative wire.
With game on touch wire to transistor tab ten to check for the missing sound to return.[quoted image]
Had some issues not related to sound problems on AP last night I had to fix first. The solenoid wire came off the "A" Drop Target so soldered that back on today, replaced some incandescent bulbs with LED's while playfield was up.
So before i try this test, the game should just be powered up and not in any test mode.
When I ground the tab of Q33 to GND (the one you circled in the pic) , I should hear a sound coming from the speaker?
I did try a little very light buffing of the pins on connector 2J9 and game started ok with proper sounds but quickly got out of "sync" again.
Update: Did the test and got sound from speaker. So yes on the test.
