  1. Capture the exact failure state

    Reversible

    Name the failing app, game, host or connection and one context that still works. Expected behavior: charge the console and output HDMI using the supported dock power sequence.

  2. Isolate the component boundary

    Reversible

    Reconnect in documented order and test dock directly to a TV. Swap only the app, host, profile, cable or wireless connection while keeping the accessory unchanged. Boundary to separate: console versus dock, Nintendo adapter, HDMI cable and TV input.

  3. Correct only the proven cause

    Reversible

    Replace the proven cable, adapter or dock; update the console. Repair the isolated app, profile, codec, port or compatibility boundary.

  4. Verify and stop safely

    Reversible

    Retest the failing context and one known-working host or app. Stop for bent USB-C, heat, liquid or damaged power hardware.
