Switch Dock No Signal / Black TV? HDMI & Dock Fixes
Nintendo Switch docked but TV no signal — dock HDMI cable, sleep mode wakes, System Settings TV output, dusty connectors, and dock board vs console port failures.
Switch dock no signal while handheld play works is a dock path problem until a second dock proves the console’s connector is toast.

Order of operations
- Official power brick firmly in the dock
- New HDMI cable; different TV port
- Remove Joy‑Cons; reseat Switch firmly (listen/feel for latch)
- Blow dust from console bottom connector
- Borrow an official dock for A/B
- System Settings → TV Output settings after you get any picture
Third‑party slim docks cause endless ghosts — validate on OEM.
Hardware
Bent dock connector pins on the Switch or failed dock PCB. Careful DIY dock opens need an 11-piece precision screwdriver set on Amazon.
Bottom line
Powered OEM dock → HDMI swap → clean connector → second dock test. Don’t send the whole Switch for repair until a known-good dock fails too.
