I'm stuck. Need help with AFM target bank

[atariaction]

Ill try to summarize:



During a game the 3 bank got stuck half way down



Put in motor test and tried to operate motor with menu buttons and flipper buttons.



The motor did not move in that test but a puff of smoke appeared from under the playfield



I removed, cleaned, regreased the motor and tested it and it was working just fine



I grounded the transistor (Q29) and the motor moved up and down but hitting the 3 targets in gameplay does not make the bank go down



When I turn on the machine the bank goes down and up to find home



The "disable motor bank" in settings is set to "no".



The up and down limit switches on the motor test fine in switch test.



I reversed the CPU to Driver ribbon cable and firmly reseated the ASIC chip and no improvement.



Still not working and still no idea where the smoke came from.



WTF? Any ideas?

Did you end up figuring this out??

Yes actually. A factory reset was the final step needed to clear the credit dot and everything has been up and running perfectly since.

Ok good, I read the tech forums and see problems and then there’s nothing afterwards lol, I just have to know what ends up happening. Thanks for the response btw
