How to Fix / Troubleshooting
Safety first: Unplug the power adapter before opening the controller housing.
- Check power adapter: Test the Aquabion power supply with a multimeter to confirm correct output voltage. Replace if faulty.
- Inspect connectors: Open the controller and verify that the power input connector and display ribbon cable are firmly seated.
- Internal fuse: Some Aquabion boards include a small replaceable fuse. Check continuity and replace with the same type and rating if blown.
- Replace display: If the board has power but the display remains blank or dim, replace the display module.
Warning: Do not bypass or upsize fuses; this can cause fire or further damage.
