General Pinball Repair Logs (Updated 11/18/23)



The purpose of this is to put logs that I don't think need a proper writeup. It should be updated periodically. Only one for now, but I should be adding more in the future.

Date: November 26th, 2021
Game: Williams Earthshaker
Symptoms: Left flippers not working, fuse F6 popping after holding down left flipper button
Solution: End of stroke switch for upper flipper was not aligned and disabling one of the windings on the flipper coil. Adjusting it fixed the issue.

Date: June 12th, 2023
Game: Demolition Man
Symptoms: garbage on lower half of the display regardless of what DMD unit I use.
Solution: Bad 6264 (don't remember the designator) on the display driver board.

Date: July 8th, 2023
Game: Gottlieb Buck Rogers Pinball
Symptoms: no displays despite repro boardset being in the unit
Troubleshooting steps: Noticed HV light for the displays was out. Checking the fuse, I could see that it was out. Replaced fuse, still popped once. Checked harness connections and one of the pins was pushed in. Replaced pushed pin and fuse didn't pop.
Solution: replaced display fuse due to bad harness connections and replaced probable cause for popped fuse.

Date: September 9th, 2023
Game: Bally Strikes & Spares
Symptoms: Sticking Flippers
Solution: Used oil in the coils, that is a no-no. Cleaned up oil and replaced sleeves.

Date: September 23th, 2023
Game: Williams Terminator 2: Judgement Day
Symptoms: Cannon not homing, missing some General Illumination
Solution: Cannon not homing issue resolved by re-aligned the switch. General illumination, like with many games of this time, had burnt connectors that needed replacement.
