Hello,

I have this T2 board not boosting 20v.
I found some moisture near J4801 just under, UPC_W_Reset, pad is almost destroyed.

When i plug type-C on all port i get 5v @0.25A; i just have one port oscilating, reseting, the port near oxydation actualy (just near top of J4801)
T2 ,U6903 and L6901 and are heating at 30° ~~.
CD3217 are not heating.

U8800 has a strange spot with moisture that i cleaned but not heating...
Please find photos attached.

Any lead please?

"UPC_W_Reset, pad is almost destroyed"
That is not a problem, is just a test point.

Please specify the CD3217 which reset the power meter.
Also check diode mode to ground at L9020/30/80.

Hello and thank you,

CD3217 is U3100_R just near nasty moisture.
L9020 & 30 : 0.374 and 0.314
L9080 : 0.330

Just to be sure it's this the one with cable attached on the picture.
