820-3437 missing ppvrtc_g3h

[Glenn]

have a 820-3437 Logic board with short on ppvrtc_g3h. I removed u1900 still short. Try to inject voltage (3V) but it only draw0.190A so around 0.58W. Any tips to next step?

Ppvrtc only give 1,3ohm.

it is liquid damage. Good cleaned before I got it..

There are only a few caps on PPVRTC, start ripping them off and praying. This may end with a dead CPU.
