Error Message: "Could Not Connect to the TV, Please Use the AC Adapter Supplied With the Console" on Nintendo Switch

What to do

1. Power off the TV and disconnect all cables from the dock.
2. Reset the AC adapter by disconnecting it from both ends for at least 30 seconds.
   • While performing this step, verify you are using the Nintendo Switch AC adapter (model No. HAC-002) and check for any cuts, kinks, frayed cables, etc.
     
   • If any damage is found, or if a different charger is being used, replacing it with the correct accessory may resolve the problem.

     You can purchase the Nintendo Switch AC adapter from Nintendo Store.

3. Undock the Nintendo Switch console and ensure it has the latest system update.
   • If the console is already up to date, restart it by holding down the POWER Button for three seconds, then select "Power Options" > "Restart."
4. Verify you are using the Nintendo Switch dock (model No. HAC-007) or the Nintendo Switch dock with LAN port (model No. HEG-007).
   
   • If a different accessory is being used, replacing it with the Nintendo brand dock may resolve the problem.
5. If you are using a Nintendo Switch dock with LAN port, update the firmware for the dock.
6. Connect the AC adapter to the dock and directly to a wall outlet, then connect the HDMI cable to the dock and directly to an HDMI port on the TV set.
   
   • If a different device is being used with the AC adapter such as a multi-outlet power strip or a power converter, remove them temporarily.
7. Power on the TV and dock the console with the console screen facing in the same direction as the front panel on the dock.
   
8. If the error message is still displayed, try the following:
   • Use a different Nintendo Switch AC adapter.
     • If the issue is resolved using a different Nintendo Switch AC adapter, the original one will need to be replaced.
   • Use a different Nintendo Switch dock.
     • If the issue is resolved using a different dock, the original dock will need to be serviced.
