Williams System 3-4-6 Complete LED Display Set – Plug & Play Replacement for Classic Pinball Machines
Upgrade your vintage Williams pinball machines with this complete LED display set—designed to replace the original plasma screens in Williams System 3, System 4, and System 6 models manufactured between 1977 and 1980. Whether you’re restoring a retro arcade game or maintaining your home collection, this kit delivers a modern, plug-and-play solution.
Proudly made in Australia, this display kit arrives pre-assembled, fully tested, and ready to install.
Each set includes 5 displays—1 master display and 4 slave displays—along with 21 precision standoffs (slightly shorter than the factory originals to avoid scratching the backglass).
Installation is straightforward and requires no modifications. The kit is fully compatible with the original cables and connectors used in these classic gaming systems—so there’s no soldering, rewiring, or technical guesswork involved.
Important: These LED displays must be installed as a full set and cannot be mixed with the original plasma units.
Additional Notes:
-
Photos show displays with protective film on the segments. Please remove this film after installation. Some sets may arrive with it already removed for your convenience.
-
Once installed, you can safely remove the high-voltage fuse from your game’s power supply:
- Bally LED kits: Remove fuse F2 (3/4 Amp)
- Williams System 3-4-6 kits: Remove fuse F1 (1/4 Amp or 250mA)
Each display set is securely boxed, sealed in anti-static bubble wrap, and includes a moisture-absorbing gel pack to ensure safe transport.
