Hi, thanks for the Answer.
I dissambled the Parts like in the Video but everything on the Platine is fixed, so the Chargingport doesnt move a millimeter even when i tried to move it. Furthermore, all the soldering-connections looks good - so I still dont know where the Problem is. Even the Charging-Cable fits good into the Port.
May another Idea would be to check the Port with an Voltage-Tester while plugged in - but I dont know where to set the Voltage-Tester - Anybody can help me out in this Case ?
thanks
