Time Fantasy (Williams, 1983): Troubleshooting and System 7 Replacement Boards
Is your Time Fantasy by Williams has a broken 'time tube' plastic, weakening flippers, won't start, or no sound? These symptoms are typical of Williams System 7 pinball machines whose original boards (MPU, driver, power supply) are now over 40 years old. The good news: the WillFA7 replacement board, Plug & Play and battery-free, brings your machine back to life.

Common Issues (System 7)
On Williams System 3 to 7 pinball machines, recurring failures stem from aging: leaking NiCad battery on the MPU (corrosion — the #1 cause of dead boards), worn 40-pin MPU-to-driver connector (the single most common failure point), resets/reboots from 5V drops (power headers and connectors need re-soldering), tired power supply capacitors, displays with missing segments, and solenoid fuse blowing (stuck slingshot or pop bumper).
Time Fantasy-Specific Issues (Forum Reports)
- Broken "time tube" plastic: the small ramp sends the ball straight into this plastic, broken on nearly every unit; the part must be remade.
- Worn playfield and broken lane guides: the machine is often incomplete (plastics, targets, posts) given its rarity.
- Won't start or resets: corroded original battery and worn 40-pin connector, typical of System 7.
- No sound: System 7 sound board to diagnose (Sound Select signals on the MPU side).
- Weakening flippers: tired coils and MPU to check.
- Missing display segments: displays and -100V power supply to rework.
Compatible Replacement Boards for Time Fantasy
- WillFA7 — 2-in-1 board (MPU + Driver) compatible with System 3 to 7 (System 7 included).
The WillFA7 replaces the original MPU and driver board (startup, logic resets, solenoid control, battery-free memory) and eliminates the fragile 40-pin ribbon cable. Purely power-supply issues (5V/12V, capacitors, power connectors) and the sound board are addressed separately; our support team can guide you.
Installation is Plug & Play, battery-free, with tutorials and free support. Contact us.
FAQ — Time Fantasy Williams
My 'time tube' plastic is broken.
It's broken on nearly every unit — the small ramp sends the ball straight into it. The part must be remade; this is a playfield issue, not board-related.
My flippers are weakening.
Tired coils, plus check the MPU. The WillFA7 replaces MPU and driver and stabilizes flipper control.
Do I need to keep the original battery?
No. The WillFA7 runs without a battery and eliminates the #1 cause of corrosion on System 7 machines.
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
- With power off, visual inspection: look for any signs of battery leakage or corrosion on the MPU of your Time Fantasy; remove the NiCad battery if still present.
- Power supply: check the 5V rail and fuses; re-solder power supply headers and MPU headers if voltage drops or the game resets.
- Connectors: re-pin oxidized Molex connectors, especially the MPU-to-driver connection.
- Solenoids: check solenoid fuses and switches (stuck slingshot) before powering back on.
- Displays: never connect or disconnect a display while powered on; test with a known good display.
- Final test: verify startup, credits, solenoids, and displays; remember the WillFA7 replaces MPU + driver. If needed, contact free support.
