820-01700 trackpad clicking but no movement

Good morning,

I have an A2141 MacBook with trackpad just clicking and keyboard logically not working not water damaged.

I found a black please inside the top let part of the trackpad connector. Replaced and also replaced trackpad, same issue.

I replaced U8210 and U6860 without changes. All the voltages are there, MacBooks boots and charges normally.

Tried another keyboard and no difference. Tried SMC reset with external keyboard and mouse and does it. I am a bit lost.

What can the issue be?

Post J6800's basic volatges: pins 12, 14, 34, 11, 15, 19.
Of course, check them with trackpad connected.

12 - 3.3
14 - 1.8
34 - 12.6
11 - 0
15 - 5
19 - 1.85

"11 - 0"
TPAD_SPI_EN also missing?

TPAD_SPI_EN is present, 1.8V without trackpad.

With trackpad connected it jumps 2 times from 0 to 0.3V

TPAD_SPI_EN_CONN has the same behavior?
