Possible Causes

Aging display backlight, Low supply voltage to display, Partial failure of control board display driver, Moisture damage behind display window

Safety first: Unplug the unit before opening the control housing.

Clean display window: Wipe the outside and inside of the display lens to remove haze or condensation.
Inspect for moisture: Look for signs of water inside the control area. Dry thoroughly.
Check connectors: Reseat any small connectors between the display and main board.
Operate in good lighting: If the unit functions normally otherwise, you may continue using it, but the display module or control board will eventually need replacement for full readability.
