How to Fix / Troubleshooting
Safety first: Ensure the unit is unplugged before opening. Mains voltage is present inside.
- Check outlet and breaker: Verify the wall outlet works with another appliance and that the circuit breaker has not tripped.
- Inspect power cord: Look for cuts, burns, or kinks. If damaged, replace the cord with a compatible Hisense-rated cord.
- Access internal fuse: Remove the rear or bottom cover to locate the small glass or ceramic fuse on the main PCB. Test it with a multimeter for continuity. Replace only with the same type and rating if blown.
- Check AC terminals: Ensure the cord connections to the PCB or terminal block are tight and not burnt.
- If still dead: The internal SMPS or main PCB is likely failed. Replace the main control PCB or seek professional service.
