5. Unplug the HDMI cable from the dock.
6. Unplug the AC adapter from both the wall and dock/console. Leave unplugged for 30 seconds to reset the AC adapter.
7. Check that you’re using an undamaged Nintendo Switch AC adapter.
   • Check AC adapter
     1. Check the model number to verify you are using the Nintendo Switch AC adapter. The model number can be found on the bottom of the AC adapter, where the cord attaches. It should read MOD. HAC-002 near the top of the text.
        
     2. Check the AC adapter for damage. Damage can include frayed or split cord, loose connectors, kinks, etc.

     Non-licensed and/or damaged AC adapters may have compatibility problems with your console.

     You can purchase replacement Nintendo Switch AC adapters from Nintendo Store.

8. Verify you are using the Nintendo Switch dock (model No. HAC-007) or Nintendo Switch dock with LAN port (model No. HEG-007).
   • A different accessory or dock is being used
     • If a different accessory is being used, replacing it with the licensed dock may resolve the problem.
9. Plug the AC adapter back into the outlet then into the dock.
10. Connect the HDMI cable back into the dock. Make sure the other end is connected to a TV/monitor.
11. Power on the console and place it in the dock. The console screen should face the same direction as the front panel of the dock.
    • LED continues to flash

      If the TV output LED continues to flash when the console is docked, try testing the console with another dock if possible.

      If the issue is resolved by using a second dock, only the problematic dock will need to be serviced. For issues with the dock only, please contact us.
