Safety: Turn off power before opening panels.

Inspect sub-boards: Check any secondary boards (UI, motor driver) for loose connectors or visible damage.
Check harness continuity: Use a multimeter to verify continuity of communication lines between boards.
Replace faulty board: If a sub-board shows signs of failure, replace it with a Samsung OEM part. If no sub-board fault is found, the main PCB may require replacement.
