Possible Causes

Aged LCD panel, backlight LED failure, loose display ribbon cable, water ingress into the display module.

Safety first: Turn OFF power and disconnect the battery before opening the control panel.

Shade test: Move the mower into the shade to confirm if the issue is the backlight or just sunlight glare.
Check connections: Open the control panel and reseat the LCD ribbon cable on the main PCB.
Drying: If condensation is visible under the display, allow the mower to dry indoors for 24-48 hours.
