I have an 820-02020 which had liquid damage around the touchbar connector JT700 - I've replace this and also order a new touchbar due to the flex connector being corroded. Before taking the damage TB off I thought I would try using both my test rig (not sure if the TB works on it) and also on a brand new one. Both are doing weird things. To best describe what is happening I done a short video which can be viewed here:
I've checked the JT700 (which seems to be the touchscreen connector of the touchbar) using diode mode and they all seems to give a value which Is the same as my donor board. I can't test the voltages as they are located underneath the logicboard and it won't show a display on an external screen (not sure if the M1 work without the screen connected)
I've also swopped screens for a brand new one and it's doing the same thing.
Can anyone shed some light on this?
