Steps

Goal: Confirm the symptom, check input and dock, then rule out cable and handshake issues.

  • Confirm the Nintendo Switch does not show a picture when docked, or the TV shows no signal.
  • Good: You have confirmed the symptom. Proceed to Check input and dock.
  • Bad: Switch works in handheld—may be dock or cable.

Check input and dock

  • Good: Correct input selected and Switch is in dock with power. The home screen appears. Done.
  • Bad: Still no picture—proceed to Check cable and power-cycle.

Check cable and power-cycle

Goal: Rule out loose or faulty HDMI cable and handshake issues.

  • Reseat the HDMI cable at both ends. Try a different port and cable.
  • Power-cycle: remove Switch from dock, unplug dock and TV for 30 seconds, plug back in, place Switch in dock.
  • If the Switch is frozen, hold the power button 12 seconds to force shutdown, then turn it back on.
  • Good: Cable or power-cycle fixes it. Switch displays. Done.
  • Bad: Still does not work—check TV output settings or call a pro.
