Take your time and be very careful around fragile plastic clips and thin ribbon cables.

Cleaning Contacts and Connectors

One of the best ways to maintain systems is by cleaning the edge connectors and power ports:

Cartridge Ports

  • Use isopropyl alcohol and cotton swabs to scrub pins
  • Blow out dust with compressed air
  • Straighten bent pins carefully with tweezers
  • Check slot for broken plastic and debris inside

Power and Video Connectors

  • Remove oxidation and corrosion from pins
  • Soak seriously corroded ports in white vinegar
  • Use contact cleaner spray on ports and jacks

Control Ports

  • Clean controller ports with alcohol and swabs
  • Soak severely corroded ports in white vinegar
  • Test button contacts with continuity setting on multimeter

Expansion Ports

  • Scrub the pins on ports for add-ons like Genisis 32X
  • Ensure a tight connection by gently bending pins

Regular cleaning prevents game issues and connectivity problems!

Replacing Belts and Gears

Rubber belts and plastic gears wear out over time and need replacement:

  • Order kits with full set of common belt sizes for the console
  • Check belt tensions against tutorial videos as you replace
  • Adjust belt positions carefully to ensure proper gear rotation
  • Grease gears, cogs, and mechanical parts with white lithium grease
  • Replace stripped or cracked gears if needed
  • Diagnose issues by observing gear movements while powered

Loose, worn or broken belts can cause playback issues for tape-based games.

Recapping Consoles and Controllers

Vintage capacitors often bulge or leak over time:

  • Order a matching capacitor kit for the console
  • Carefully desolder and remove old caps
  • Replace each cap one by one matching polarity and voltage
  • Avoid damaging thin traces and pads while soldering
  • Test continuity between pins after installation
  • Check console and controller boards for damage

Even non-bulging caps can degrade and benefit from replacement after 20+ years.

Cleaning Games and Cartridges

Keeping games and carts clean ensures reliable performance:

  • Use 90%+ isopropyl alcohol with cotton swabs
  • Gently clean edge pins and ensure they are straight
  • Soak badly corroded games in white vinegar then scrub
  • Use compressed air to blow out dust from cart slots
  • Carefully open carts to clean contacts – avoid damaging labels
  • For disc based games, use proper CD/DVD cleaners only

Inspect games before playing to spot damage, corrosion or large dust deposits.

Common Audio and Video Mods

Modifying the original inputs and outputs can greatly improve display and sound:

Audio Mods

  • Replace capacitors on audio circuit boards
  • Install superior isolation transformers and caps
  • Add stereo audio output instead of mono
  • Bypass low quality RF modulator with direct RCA cables

Video Mods

  • Upgrade composite video with S-Video or RGB video output
  • Replace capacitors and run traces to output jacks
  • Install high quality shielded cables to TV
  • Sync to HDMI with upscalers like Retrotink for lag-free display

Storing and Displaying Consoles

Use proper storage methods to avoid temperature and humidity damage:

  • Keep consoles in climate controlled room around 65-75°F
  • Avoid attics, garages and basements with extreme temps
  • Use gel packs and desiccants to control humidity
  • Store vertically to prevent stacking stress
  • Open plastic bags and run devices yearly to check functions
  • Display consoles out of direct sunlight to prevent fading
  • Keep areas dusted and use glass cabinets for pristine systems

Improper storage accounts for a large portion of vintage electronic degradation.

Handling Precautions

Vintage consoles and games require gentle care in handling:

  • Avoid touching circuit boards unless necessary for repair
  • Never pull on cables – grip connectors by the plastic housing
  • Keep food and drinks far away from electronics
  • Hold carts by the edges to avoid smudging labels
  • If a game doesn’t load, gently reseat it instead of forcing
  • Let devices warm up to room temperature before powering on
  • Transport in protective cases and original packaging if possible

Careful handling prevents costly damage and preserves value.

Maintaining Disk and Tape Drives

Moving-part disk and tape drives need servicing to stay operational:

Floppy Drives

  • Use isopropyl alcohol to clean read heads
  • Carefully lubricate rails and gears with white lithium grease
  • Replace worn drive belts with accurate sizes

CD Drives

  • Clean lenses with a CD laser lens cleaner kit
  • Apply friction toCD hub with rubber band to increase grip

Cassette and VCR Parts

  • Demagnetize tape heads to improve tape playback
  • Replace pin belts, gears, and rubber components

These preventative steps greatly improve load success and playback performance.

Testing After Maintenance

After any repairs, thoroughly test the console:

  • Power on for 30-60 minutes to check for shorts, overheating
  • Try inserting and removing game carts multiple times
  • Load games from each genre to test various chips
  • For disc systems, check both audio CDs and games
  • Check controller inputs by entering button combinations
  • Compare video and audio to properly maintained model

Don’t assume repairs succeeded – always verify.

Seeking Repair Help

For complex repairs beyond your skill level:

  • Search for console repair shops in your area or mail-in shops
  • Join collector forums and ask trusted members for referrals
  • Read shop reviews and ask about warranty coverage
  • Get repair cost estimates and timeframe before committing
  • Ensure they have experience fixing your particular console
  • Backup save data before sending in for repair

Vintage expertise is hard to find – thoroughly vet any repair shops.
