Genuine Lg part
By: Lg

  • Can cause control errors, loss of settings, or unexpected resets when failing
  • Often replaced when the control board reports memory-related faults or becomes unresponsive
What's included:
  • One memory IC (board-mounted)
Install notes:
  • Board-level replacement only; requires soldering or rework tools and ESD precautions
  • Disconnect power and fully discharge capacitors before servicing
  • Only replace with the exact part number to ensure compatibility
