STORY: long version.
Hey guys I am looking to you for knowledge of parts and expertise.
I have TFTC and the lower right flipper was in a bind and only flipping part way up and then stopping.
I took it apart and found some alignment issues both at the end of the linkage being sloppy and the depth at which the shaft was set in the PF. I also checked plungers, arms and coil stops and all look very good outside of some gunk which I cleaned up. I readjusted both alignment issues and the flipper has full power and flips all the way up with full range... But at the end of the flip it sticks in up position for a fraction of a second and falls on its own accord. I checked contact of EOS via DMM and adjusted the open gap to aprox 3mm. No change. I then proceeded to swap the diode and band and wires all oriented the same as I took pictures to be sure. Here is the NOOB move. I got in a hurry mounted it back up and forgot to clip the diode end leads :/ I blew 5A slow blow F5 on PPB board. I removed solenoid and clipped leads that were shorting now against the backing plate. I replaced the fuse and turned machine on pressed start and flipper went to up position. I turned it off and it fell. I rechecked above things. Realized that the gap was not right on the second set of leaf switches at the flipper button. I am sure this was me messing with things. I fixed this and flipper is now just dead it does not go up on startup but does not fire either. I then moved to the under PF flipper control board on the left side of the cabinet. It also blew 3A slow blow fuse F1 so I replaced this and checked all above again. No change. I then looked through the schematic and could not figure out for the life of me if A,B,C flipper was lower right flipper so I followed the line on switch B and swapped out Q12 on flipper board 2n3096. I then realized the one I pulled tests fine
Still the same result when everything installed. Note: I did not mess up the left flipper it is still good with new component. I then noticed a second reference chart on page 84 of the manual that stated which flipper was A (right),B (left),C (upper right)
(damn digital copies)
1. Am I on the right track? lol
2. Are the following driver transistors correct?
Right flipper(A) driver Q6
Left flipper(B) driver Q12
Upper right flipper(C) NAND gate into Q18
3. Should I replace anything more than the correct driver transistor on the flipper driver board Q12?
4. Anything else to check or replace while I am elbows deep?
Thanks and sorry it got really long winded.
