Step by step

  1. Check the outlet and strip Plug something else into the same socket.
  2. Swap the adapter Use a known-good adapter with the same specs.
  3. Remove all accessories Unplug controllers, memory cards, expansion add-ons and any Sega CD or 32X.
  4. Try a known-good cart or disc A bad game can look like a dead console.
  5. Try a known-good video setup Another cable and another TV.
  6. Check the power switch Switches wear and corrode.
  7. Look for a blown fuse Fuses such as F301 on a Mega-CD 2 or PS604 on a PS1 can kill a console.
  8. Inspect visually Open the console, look for burned parts, crusty residue and cracked joints.
  9. Stop and decide If nothing external explains it, decide whether to continue to board-level work or find a repairer.

Tips, tales and maybes

Found in write-ups and forum threads. These are other people's reports, not tested by us.

  • Story (Low confidence). An N64 with a wireless controller adapter crackled and shut off. Using normal controllers cured it and suggested the console could not cope with the adapter's draw. Source
  • Story (Medium confidence). A Mega-CD 2 with no signs of life only needed its F301 fuse. Source
  • Tip (Low confidence). A Saturn black-screen thread listed power supply, video cable type and BIOS or memory cart interference as the first things to rule out. Source
