Safety: Unplug the appliance before opening any panels. Capacitors on the PCB can retain charge; avoid touching components unnecessarily.
Steps to diagnose:
- Verify outlet: Test the outlet with another device.
- Inspect power cord: Check for visible damage. Replace if compromised.
- Access main PCB: Remove rear panel and locate the control board. Check that the mains connector is fully seated.
- Check fuses: Look for any onboard fuses and test continuity. Replace only with identical type and rating.
