Striker (Gottlieb, 1982): Troubleshooting and System 80A Replacement Boards

Your Striker by Gottlieb won't start, has missing display segments, weak flippers, or random resets? These symptoms are typical of Gottlieb System 80A pinball machines whose original boards are now over 40 years old. The good news: the GottFA80_Plus replacement board, Plug & Play and battery-free, brings your machine back to life.

The GottFA80_Plus replaces CPU, driver, and power supply in a single board.

Common Issues (System 80A)

All Gottlieb System 80A pinball machines share the same weaknesses as System 80, with added complexity from alphanumeric displays and speech synthesis:

  • Leaking NiCad battery: soldered to the MPU board, it corrodes traces and components over time — the #1 cause of dead boards. Remove it immediately.
  • Floating grounds: the original ground wiring is undersized and causes resets and erratic behavior. Ground mods are virtually mandatory.
  • Edge connectors (the "Gottlieb plague"): oxidized edge connectors cause display faults, missing digits, and intermittent failures. Clean or replace them.
  • Corroded connectors: Molex connectors, especially the MPU-to-driver connection, lose contact and require re-pinning.
  • Drifting power supply: the 5V and 12V rails sag over time; trim pots and aging capacitors need attention.
  • Sound board: leaking capacitors, cold solder joints, and failing ROMs cause weak or absent sound and speech.
Multimeter check on Gottlieb System 80A board — Striker
A multimeter is essential to check voltages, fuses, and continuity.

Striker-Specific Issues (Forum Reports)

  • Displays with missing segments/digits: edge connectors to clean or replace first.
  • Battery damage on CPU board: frequent corrosion after 40+ years.
  • Weak flippers: often worn EOS contacts and flipper switches, plus a crushed coil stop.
  • Weak or absent sound: sound board capacitors leaking.
  • Random resets: floating grounds and oxidized connectors.

FAQ — Striker Gottlieb

My flippers are weak.
Check the EOS contacts, flipper switches, and coil stop — these are mechanical wear items. The board side handles logic only.

My Striker resets randomly.
Floating grounds and oxidized connectors are the usual cause. Apply ground mods and re-pin connectors; a GottFA80_Plus stabilizes the MPU.

Is the GottFA80_Plus compatible with my Gottlieb System 80A?
Yes. The GottFA80_Plus covers System 80, 80A, and 80B. If in doubt, contact us.

Do I need to keep the original battery?
No. Our boards run without a battery and eliminate the #1 cause of corrosion.

How long does installation take?
Installation is Plug & Play: just a few minutes, no soldering required, with tutorials and free support.

Does a battery-free board retain settings and high scores?
Yes. Modern replacement boards use NVRAM: no battery, no corrosion, and settings are preserved when powered off.

Step-by-Step Diagnostics

  1. With power off, visual inspection: look for any signs of battery leakage or corrosion on the MPU of your Striker; remove the NiCad battery if still present.
  2. Power supply: measure the 5V rail and verify it reaches the MPU (re-solder the voltage regulator or Q1 if voltage drops).
  3. Grounds: apply ground mods between the boards (CPU, driver, power supply, sound).
  4. Connectors: re-pin oxidized Molex connectors, especially the MPU-to-driver board connection.
  5. Displays: never connect or disconnect a display while powered on; test with a known good display.
  6. Final test: verify startup, credits, solenoids, and displays; if needed, contact free support.
