Mbp 820-02773 M2 2022 no touchbar

[Mortentoft]

Hi fellows. After a liquid spill and previous repair attempts, I’ve managed to get the MacBook Pro to boot, but the touchpad isn't working. I’ve tried using a different top case, but it didn't have any effect. I’ve looked at the schematics and are trying to understand it, but need assistance. On RT702, I get 1.76 volts on both sides, but nothing is coming out from QT700. I am wondering if power only flows when the LID is active. Is there anyone who can guide me in the right direction?
Thx

The same signal IPD_LID_OPEN_1V8 goes to trackpad.
Is good of course, if trackpad works.
And QT700 can't open, being P-channel MOSFET; that's correct.
In fact even the name, DFR_LID_OPEN_L specifies to be low (0V), when lid is open.

Check other voltages and signals on JT700; compare with good board, if possible.
