I now working on a 820-3662 board with no signs of water damage and really looks like new.
EFI shows tsOp error and reading -124
Tried new trackpad and cables with no change
Connector looks like new

All hints I can find are measurement on pin 19 shows 0.502 in doide mode and should be around 0.640

New to this problem and help needed =)

Checked R5370 and R5371 and the same measurements in diode mode
Removed the silicone around SMC and put some flux around it then a quick heat up.

Now measurements seems fine 0.637 in diode mode and tsOp error are gone.

Some testing left
