Lanbopro Display Power or Communication Failure

Display is completely blank but interior light still works.

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 display connector, Failed display PCB, Faulty low-voltage supply from main control board

Safety first: Unplug the cooler before accessing the display.

Check power: Confirm the unit is cooling and the compressor runs; this indicates main power is present.
Inspect display wiring: Remove the front control panel and verify the display board connector is firmly seated.
Replace display board: If wiring is intact, replace the display/control board.
Main board check: If a new display does not light, the main control board may not be supplying low-voltage power and should be replaced.
