Second repair apple MacBook A1707 notebook touchpad keyboard can’t be repaired with fault.
Second, the touch panel keyboard of Apple MacBook A1707 notebook can’t be used. It was directly installed on the machine for measurement. When the problem was found, the interface voltage was wrong, so the interface was directly changed, tested again, and troubleshooting was carried out.

[Malfunction] Notebook touchpad keyboard can’t be used.
[maintenance process]
The notebook touchpad keyboard can’t be used when the same machine is repaired. Dismantle the machine, see if the blue bridge has been repaired, remove the motherboard, measure the resistance of each interface, and the related voltage is normal. I wonder if there is a problem with the previous bridge, so I find a bridge and replace it, and the fault remains the same.

It is directly installed on the machine for measurement, and the problem is found. The interface voltage is wrong. It is normal to unplug the touch panel and measure it again, but it is not installed correctly. The interface looks normal, and there is no damage or corrosion.
So change the interface directly, test again, and troubleshoot. Still not careful enough to solve big problems carefully.
