How to Fix / Troubleshooting
Safety first: Unplug the unit immediately. Do not attempt to power it on again. Risk of electric shock or fire.
Steps to inspect:
- Visual inspection: After allowing time for capacitors to discharge, open the housing and inspect the mains filter board and main control PCB for exploded components or burn marks.
- Check internal fuse: Test the internal fuse for continuity. If blown, do not simply replace it without identifying the root cause.
- Replace assemblies: Replace any visibly damaged boards (typically the mains filter and/or main control PCB) as complete units.
- Use surge protection: After repair, consider using a surge-protected outlet to reduce future risk.
