Problem description
Fixing an issue where the Nintendo Switch shows no image on TV when Docked
Symptoms
- No image on TV when Docked
Solution
- Check if the port is damaged on Switch and the dock, try replacing the port, may be loose or improperly soldered.
- Try replacing P13USB.
- Check ferrite chokes/beads between P13USB and the port for continuity, check capacitors between as well. Try replacing all of them, even if they look OK.
- Sometimes replacing M92T36 will fix it, especially if the console also has charging issues like for example charging from just one side.
- Otherwise it may be a tricky case to solve as these data lines are high frequency and sensitive, sometimes it's not always solvable unless you have a good high frequency oscilloscope and are familiar with USB-C/HDMI video out communication protocols.
