Try these steps...

  • Open your calculator and remove the logic board
  • Inspect the logic board, especially around the connectors and look for corrosion.
  • Inspect both sides of the board.
  • Put your board in a container with >90% isopropyl alcohol and let it sit for a while.
  • Use a soft brush, like a toothbrush and lightly brush away any corrosion you see.
  • Rinse in alcohol and repeat.
  • Let it air dry for a day.
  • Re-assemble and hope for the best.
