How to Fix / Troubleshooting
Safety first: Unplug the unit before opening the control area.
Step-by-step:
- 1. Check mains supply: Avoid using long extension cords. Plug directly into a stable outlet.
- 2. Inspect connectors: Remove the top/front cover and reseat the connectors between the main PCB and display board.
- 3. Look for moisture: If there is condensation or water on the boards, dry them thoroughly and allow 24 hours before re-powering.
- 4. Examine capacitors: On the main PCB, look for bulging or leaking capacitors in the low-voltage power supply section. If found, the board should be replaced.
- 5. Replace PCB if needed: Persistent flickering usually indicates a failing power supply on the PCB, requiring board replacement.
