Possible Causes
Incorrect mains voltage, Unstable power supply, Faulty power supply section on PCB, Misconfigured voltage selector (if present)
How to Fix / Troubleshooting
Safety: Do not attempt to modify mains wiring. Unplug before internal checks.
- Verify supply: Confirm that the unit is connected to the correct voltage as specified on the rating plate (e.g., 220–240 V). Avoid using long, undersized extension cords.
- Try another outlet: Plug the unit directly into a different, known-good outlet without adapters.
- Check for surge devices: If connected through a UPS or inverter, test directly on mains power.
- Internal inspection: If the error persists on correct power, the line monitoring circuit or power supply on the PCB may be defective and the board should be replaced by a technician.
