Possible Causes

Input voltage out of range, Faulty internal SMPS (switched-mode power supply) on control board, Loose mains connector or power cord, Surge-damaged control board

How to Fix / Troubleshooting

Safety first: Disconnect from mains before any disassembly. Do not attempt live-voltage measurements unless you are trained and equipped.

Steps:

  • Check outlet: Test the wall outlet with another appliance. Avoid using long extension cords or multi-plug adapters that may cause voltage drop.
  • Inspect power cord: Examine the Philips power cord and plug for cuts, kinks, or burn marks. Replace the cord set if damaged.
  • Internal connector check: Open the housing and verify that the mains input connector, strain relief, and wiring to the main control board are secure and not discolored.
  • Board inspection: Look for bulging capacitors, burn marks, or cracked solder joints in the power supply section of the main PCB. If present, the board should be replaced.
  • Surge protection: After repair, use a surge-protected outlet to reduce future damage risk.

Warning: The power supply area contains high-voltage components. If you are not experienced with electronics repair, contact a professional technician.
