Is your Pink Panther by Gottlieb (1981) suffering from failing displays, missing digits, a persistent slam tilt, resets, or refusing to boot? On this Gottlieb System 80 pinball machine, the cause is almost always the connectors, the grounds, and the CPU/Driver boards. Here is the essential information and the compatible System 80 replacement boards.

Common Issues on the Pink Panther (System 80)

Like all Gottlieb System 80 machines: aging CPU/Driver boards, crashes and resets, slam tilt, failing displays, unreliable grounds and connectors, leaking battery.

Typical corrosion from a leaking battery on System 80: must be addressed first.

Specific Issues on the Pink Panther (Forum Reports)

  • Displays: digits not showing (reported case: the "1" missing on players 3 and 4) — clean the display connectors with an eraser.
  • Slam switch: a slam switch left open or dirty is a classic cause of boot failures.
  • Limited solenoid driving: Gottlieb repurposes lamp transistors to drive an under-playfield transistor that activates a solenoid — a known weak point.
  • Under-playfield pop bumper boards: modifications recommended if they are original.
  • Connectors & ground mods should be done first.

Resets, weak displays, grounds, and solenoid driving issues are resolved by switching to the GottFA80_Plus (rebuilt power supply and driving); the Lisy80 helps with diagnostics.

FAQ — Pink Panther Gottlieb

Digits are missing on my Pink Panther displays?
Start by cleaning the display connectors; if the problem persists, the rebuilt power supply and driving in the GottFA80_Plus restore stable displays.

My Pink Panther freezes at startup?
Check the slam switch and grounds; ground mods help, and the GottFA80_Plus makes the whole system reliable.

Should I do the ground mods?
Yes on System 80 — or switch to the GottFA80_Plus.

Should I replace the battery?
Our boards work without a battery: no more corrosion.

How long does it take to install a replacement board?
Installation is Plug & Play: just a few minutes, no soldering, with free tutorials and support.

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

Step-by-Step Diagnostics

  1. With power off, perform a visual inspection: look for any signs of battery leakage or corrosion on your Pink Panther's MPU; remove the NiCad battery if still present.
  2. Power supply: measure the 5V rail and verify it reaches the MPU (reflow the solder on the voltage regulator or Q1 if the 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 link.
  5. Displays: never connect or disconnect a display while powered on; test with a known good display.
  6. Final test: check startup, credits, solenoids, and displays; if needed, contact free support.
