You are in the right place if: The PS1 shows a disc-read error, spins up then stops or fails to recognise discs.

Before you start

  • Never look into the laser.
  • Never turn the pot without marking where it started.

Board revisions and models

PSone and original PS1 differ. ConsoleMods names PSone capacitor C705 for disc detection issues.
