This was a liquid damaged machine but no liquid damage was on LB. Left ports were replaced.
The left USB-C ports do not communicate USB data but do charge the unit.
None of the zener diodes are damaged on the data lines and the fault covers both left ports.
Looking at the schematics I see U2800 is on this channel as well as both the CD3217's
Looks SOC U3900 "T2" is also in the mix here.
Where do I start?
