Over the years, I've learned a few useful tricks to repair or resurrect recalcitrant consoles. Some of them may even be useful! Stuff about controller repair, some troubleshooting and replacement parts, etc. I actually discovered / wrote much of this before I realized that a bunch was already in the Intellivision FAQ. If there are inconsistencies, then the FAQ is probably right. Consider this supplemental material. You can also find great info here. If I've borrowed or gotten help from some other source, I try to give credit where it's due.

So far, these are things I've actually accomplished in terms of repairing or modifying and Intellivision unit.

  • Repair / replace the voltage supply ribbon cable in an INTV System III (or similar) Master Component (Details)
  • Identified a defective AY-3-8915 chip in a Sears Super Video Arcade (Details to come)
  • Repaired heavily used controllers' mylar guts in various ways (Details to come)
  • Replace the cartridge port (Details)
  • Replaced the RF Modulator UM1285-8 unit on several systems (Details)
  • Repair fatigued controller connector (Details)
  • Added a connector to the power LED in an INTV System III (Details to come)

You can find the well-worn tech stuff in the Intellivision FAQ, too - specifically, the Troubleshooting and Technical sections.
