Charger display is on but backlight is dim or unreadable; unit still charges.

Safety first: Turn off power before removing the front panel.

• Check contrast/brightness (if available): Some models allow adjustment; verify settings.
• Inspect ribbon cable: Reseat the display ribbon cable on both ends.
• Check for moisture: Look for condensation behind the display window. Dry and correct any gasket issues.
• Replace display module: If the backlight remains dim or off, replace the Sun Country Highway display module.
