Recap first
Recap before anything else. Do not install a new screen, flashcart, or any other mod until the board has been fully recapped and tested. Building on leaking capacitors wastes parts and hides the real fault.
Recap First
If you take one thing from this wiki, take this: the full recap is the number one fix for a Game Gear. The original surface-mount capacitors dry out and leak over the decades, and that single failure mode causes the symptoms people most often blame on dead chips.
Why it comes first
Leaking capacitors are the direct cause of no sound, distorted or crackling audio, dim or wavy video, and a console that refuses to power on. Replace them all and these problems clear up together. Spending money on a screen or flashcart before recapping just means installing good parts onto a failing host.
Work through the recap in clear phases so nothing gets skipped.
- DiagnoseNote the symptoms and inspect both boards for leaked electrolyte and corrosion.
- Source capsOrder a full kit from Console5, ZedLabz, or Retrosix matched to your board.
- ReplaceRemove every old capacitor, clean the pads, and solder in the new ones with correct polarity.
- CleanNeutralize and wash away any residue so corrosion stops spreading.
- TestPower on and confirm audio, video, and stable power before reassembly.
Only once this is done and verified should you move on to the optional upgrades.
