How to Fix / Troubleshooting
Safety first: Turn OFF the mower and disconnect the battery before opening the control panel.
- Check contrast/brightness (if available): Some models allow adjustment; ensure it is not set too low.
- Inspect display connector: Open the panel and reseat the display ribbon cable or connector.
- Check for moisture: Dry any condensation around the display.
- Test operation: If the mower functions but the display remains dim or blank, replace the display module.
Operating without a readable display is unsafe because you cannot see warnings or settings; repair promptly.
