I contacted TM Support, they sent me a PDF disassamebly guide.
The problem was 100% same as this -->

SOLUTION;
* At the bottom of the Joystick, unscrew the 4x screws.
* A small PCB is expoised, remove the lefthandconnector
* unscrew the DIN-connector
* Push the removed white connector up into the base so it pushes the DIN upwards out of its place.
* Now your exposed the wiring.
* Get the soldering iron and some solder.
* Resolder the broken wires.
* Test.. using the Firmware Uploader
Literally.. within 5 minutes it was fixed.
