Display is very dim, flickering, or unreadable, but charging still works.

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

• Check contrast/brightness: If available, adjust display settings via the menu or app.
• Inspect connections: Reseat the display ribbon cable or connector on both the display and main board.
• Check for moisture: Look for condensation behind the display lens and dry thoroughly if present.

If the display remains dim or flickers, the display module likely needs replacement, though the charger may continue to function via app control.
