NES with the blinking power light

Games would only boot after a dozen tries. A new 72-pin connector, the lockout chip disabled, and the owner's cartridges cleaned.

Sample Sample content, to be replaced before launch.

After the repair Before the repair

What came in

A front-loading NES-001 with the classic symptom: grey screen and a blinking power light with almost every game. It came with 14 cartridges.

What we did

  • Replaced the 72-pin cartridge connector
  • Disabled the lockout chip, so a slightly dirty cartridge still boots
  • Cleaned and tested all 14 cartridges; two needed their contacts polished
  • Ran the 4-hour burn-in on a game's attract mode

Every cartridge now boots on the first try.
