I refurbish a 820-02020-11 which had a bad liquid damage. I'm short before to finish it. My last problem (i hope so) is the touchbar - it only shows green vertical stripes (see picture attached).
Unfortunately I don't have a known good touchbar. So i tested the board with three different touchbars (theoretically they could all be damaged).
One of them shows nothing - probably dead. The other two touchbars shows the same picture - only green stripes.
How could i go about troubleshooting here?
