Re: hp 8460p schematic please guys
This is not a common issue. In all the boards Ive seen Ive had maybe 1 where the GND Fet for the buck converter is stuck open.
Yet again if this Fet is already shorted open its ALREADY done its damage. 19v at a few amps would destroy the next item in line on that board. Usually the inductor.
We can go around and make up worse case scenarios but truth is this isnt common from my experience.
