These symptoms overlap when the Switch shows no picture on the TV and the user starts to wonder if the console is dead. Use this page to separate a dock/output path problem from a real power or startup fault.
Choose dock not working when the Switch still behaves normally in handheld mode but fails on the TV or dock charging path. Choose not turning on when the console itself shows little or no handheld startup response even away from the dock.
Fastest clue: A healthy handheld mode points more toward dock trouble than startup failure.
If the handheld screen is on but blank, compare not turning on vs black screen as well.
TV output, HDMI handoff, dock power, or USB-C dock connection issues.
Battery, charging, startup, or power-management faults.
A user may describe both simply as not working, but handheld behaviour separates them fast.
Dock faults often stay accessory-led; startup faults escalate toward console repair faster.
That tells you whether the stronger next guide is dock-related or true startup-related.
These quick answers help separate TV-output failure from console startup failure.
Yes. A Switch can work normally in handheld mode while the dock path fails.
If the console shows no meaningful handheld startup or charge response away from the dock, the startup guide is more appropriate.
Take the console out of the dock and test handheld behaviour first.

Use this when the Switch behaves normally handheld but fails on the TV or dock path.
Use this when the console itself shows little or no startup response.
Compare this if the handheld screen may be blank rather than fully dead.
