Safety first: Disconnect power before accessing the control electronics.

Steps to correct display anomalies:

Power cycle: Unplug for 10 minutes and reconnect to reset the control logic.
Inspect for moisture: Check behind the control panel for signs of liquid ingress or corrosion.
Check connectors: Reseat the connectors between the display module, UI PCB, and main PCB.
