Sharp Display / User Interface Power Issue

Digital display is blank or flickering, but the freezer still cools.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose connector to display board, Failing display PCB, Low voltage from main control board to UI, Moisture damage to control fascia

Safety: Unplug before removing the control panel.

Steps:

Access UI board: Remove screws securing the control panel and gently pull it out.
Check connectors: Reseat the ribbon cable or harness between the main PCB and display board.
Inspect for damage: Look for corrosion or burn marks on the display PCB. Replace if damaged.
Main board output: If the display remains blank with a known-good UI, the main PCB may not be supplying correct low-voltage power. Replace the main PCB.
