  • Unplug your Vizio TV from the socket.
  • Unplug all cables or smart plugs.
  • Plug another device into the socket that uses a similar amount of power as your TV.
  • If the other device works properly, plug your TV into the socket to see if the blinking light continues.
  • Alternatively, try a different functioning wall socket to ensure a consistent power supply.

Step 3: Inspect the Power Cable

  • Examine the power cable for any damage or knots.
  • Check the power connector on your TV for rust or corrosion, which can hinder proper power supply.
  • If damage is found, replace the cable or connector to ensure an adequate power connection.

Step 4: Troubleshoot HDMI Connections

  • Turn off and unplug your Vizio TV.
  • Disconnect all cables, including HDMI connections.
  • Clean the cables and connectors with a soft brush or air compressor.
  • Reconnect the cables and power on the TV to check if the issue is resolved.
  • Consider trying a different HDMI port if the problem persists.

Step 5: Check the Power/Main Board and Backlight Inverter

  • If external checks don’t resolve the issue, it’s time to delve inside.
  • Carefully open your TV case to access the power/main board and backlight inverter.
  • Ensure the power socket on the board is receiving power.
  • Verify that all components on the board are receiving power.
  • Inspect for any damaged parts or capacitors.
  • Use a voltmeter to test the backlight inverter and its cables.
  • If the boards and inverter seem fine, consider the possibility of a failed backlight.

Step 6: Seek Professional Help

  • If the issue persists after attempting these steps, it might be best to consult a professional technician or the manufacturer’s support.
  • Remember, tampering with internal components might void warranties if not done properly.
