Hardware Docking Station Fast Blinking

[LordAdonis]

Hey everyone,
Currently having a problem.
One docking station I had just stopped working. It started blinking fast and after that it stopped doing anything else than first light up.
Now I changed the motherboard of my working switch into the faulty one to check if it is the motherboard. Yes, it worked, but one day later, also starts blinking fast and wont work anymore. Anyone has ideas what to check?

Most likely something is broken in your dock.
Either the USB-C port or maybe some other damage like water damage (from a previous owner).
You can inspect the connector to see if some pins are bent/broken.
Maybe you need to take it apart to look for some other damage.
