Leslie used our desoldering iron for the first time. She was proud to collect this mound of solder. Kind of an interesting picture close-up. She replaced the 40-pin interconnects on numerous Williams’ System 3-7 CPU and driver boards.

Baywatch

Customer brought in a Baywatch that had been sitting in storage for 10 years. It is a reimport game and the customer was afraid that the transformer had been wired wrong.  Turning the game on resulted in no lamps and a scrambled display.  This game uses the very large (and very expensive) 192×64 DMD display […]

Scottsdale, AZ Beautiful Italian game with a Risque backglass. Controlled lamps were very dim. Checked the controlled lamp voltage and it was only at 2.3 volts. This is supposed to be around 5V.

Scottsdale, AZ The only tri-level game from Bally. None of the insert/controlled lights were working also the playfield GI was out. There is not much to the controlled lighting circuit.

Scottsdale, AZ The up/down ramp posts were not working on this game. Zaccaria used some heavy duty coils for these posts and even put heat sinks on the individual transistors but even that was not enough to keep the game from blowing them out. After replacing the two transistors both posts worked in solenoid test […]

Peoria, Arizona Game was reported to have a severe reset problem. The game would reset anywhere from withing 10 seconds to 5 minutes after turning it on. We turned this game on and let it run while repairing the TOM.  It didn’t reset once.  Of course, that’s the way it always works once you have the tech […]

Scottsdale, Arizona Game was only booting intermittently and was resetting when it did boot. Initially we looked at the CPU for the customer as we didn’t have the entire game at our shop.  CPU checked out fine on the test bench, all outputs worked and we did not see any resetting.  We brought the board […]

Sharpshooter II Gameplan MPU-2

Circuit Board Repair 1 April 2011 | Comments Off on Sharpshooter II Gameplan MPU-2

Customer was having trouble getting their Sharpshooter 2 MPU to boot. It had the typical gameplan battery rot (actually it was very mild) and they had rebuilt the reset section, replaced the old PROMs with EPROMs and rejumpered, replaced 3 corroded sockets and still could not get the board to boot, so they called in […]
