820-02773 - without keyboard and trackpad

[Palhano]

The device came into contact with liquid. It is close to the QF910, UF900, UF960 and UR300.

I cleaned everything, replaced components and the Mac started working again. However, sometimes the keyboard and trackpad stop working. I connected external devices and they don't work either. However, everything works before the system starts, when I enter the boot option.

Any tips?

I went back to work on the UR300 and it seems to have resolved the issue!
