Switch handheld mode works fine, but plugging into the dock gives you nothing on the TV? Or the dock won't charge the console? Both are common, and both are repairable.
On a PS5 or an Xbox, the HDMI port is on the console itself, so the repair lives entirely on the main board. The Switch is different. The HDMI output is on the dock, with the console providing video through its USB-C port and the dock converting that signal out to HDMI through a small chipset and the HDMI connector. That means a "no video on TV" problem on a Switch could be one of three places: the HDMI port on the dock, the HDMI driver chip inside the dock, or the USB-C port and adjacent components on the console itself.
The fastest way to narrow it down is the handheld test. Does the Switch still work normally in handheld mode? Plays games, charges when plugged in with the wall adapter directly into the console, screen looks right? If the answer is yes, the console is healthy and the fault is on the dock side. That's usually the case.
If the console also has trouble charging through its own USB-C port or behaves erratically off the wall adapter, the fault is more likely on the console board, and the repair work is on the USB-C port or the M92T36 power-management chip rather than the dock.
Worth flagging because it comes up constantly: certain third-party Switch docks have damaged consoles by feeding incorrect voltage or signalling through the USB-C connector. The M92T36 chip on the Switch console is the most common casualty, and once it's blown the console can lose its ability to output to the dock (and sometimes to charge properly). If you've been using a non-Nintendo dock and the problem started after that, mention it. The repair scope is different when the console side is also damaged.
For dock-side HDMI repair, the dock comes apart, the damaged HDMI connector or driver chip is removed under microscope, the replacement is installed with controlled hot-air rework, and the dock is tested with a console before reassembly.
For console-side work, the Switch comes apart down to the motherboard and the damaged port or component is replaced using the same micro-soldering techniques. The console side is more involved because the layout is tighter and there's less working room on the board.
The other extremely common Switch repair is Joy-Con drift. If your Switch has both, bring it in together and we can quote the work as one job.
Removal and replacement of the HDMI connector on the Switch dock when the port is physically damaged or has internal solder joint failure.
Diagnosis and repair of the small HDMI driver chip inside the Switch dock that's known to blow when third-party docks or bad USB-C cables damage the console-to-dock interface.
Component-level repair on the USB-C connector inside the dock that the console plugs into. This connector takes mechanical stress every time the console docks and undocks.
When the fault is actually on the console side, not the dock, we repair or replace the USB-C charging port on the Switch itself.
