Safety: Disconnect from mains before inspecting the power cord or internal wiring.

Steps:

• Verify outlet: Plug another appliance into the same outlet to confirm proper voltage. Avoid using extension cords or power strips.
• Inspect power cord: Check the entire length of the cord for cuts, kinks, or burn marks. Replace the cord if damaged.
• Check internal connections: Remove the rear panel to access the power entry point and control board. Ensure the main power connector is fully seated and that there are no signs of overheating.
• Look at the power supply section: On the control board, inspect the area near the AC input for burnt components or bulging capacitors.

Repair guidance: If the outlet is good and wiring is intact, the internal power supply on the main control board is likely faulty. Board replacement is recommended and should be done by a qualified technician due to shock risk and the need to correctly transfer all connectors.
