Game cartridge not reading when inserted into the Switch

Symptoms

  • Game cartridge not reading
  • Game cartridge not detected as soon as being inserted

Solution

  • Check for bent pins in the slot, liquid damage around the game cartridge/headphone-jack/touch screen connector component.
  • In some cases when there is no apparent physical damage the board may need to be replaced, but this is increasingly difficult to do as there are many revisions of this board and the touch screen which cause no touch issues, and Nintendo seems to be locking this part out from replacement with recent firmware updates. More research needs to be done on the board revisions.
