GoKawiilNintendo publishes troubleshooting steps for Switch 2 TV connection issues
Nintendo has outlined a step-by-step process for fixing Switch 2 docks that fail to connect to a television, starting with unplugging all cables for about 30 seconds before reconnecting. The guidance covers checking for cable damage, confirming the wall outlet works, and verifying the AC adapter is properly seated. Nintendo also notes that third-party adapters must supply at least 54W, more than the original Switch required, to maintain a stable TV connection.
