820-3332 short to ground on ppvrtc_g3h

[jgraffis]

I'm working on this 820-3332 that came in today. don't no the history. it has green/red light, pubs_g3h is at 12.6v, next rail i checked was ppvrtc_g3h, Found that it had 0.223v, checked and confirmed that it had a short to ground. chased it back to u1800.

i dont have a machine to recall a chip of this size. is it even worth messing with or just a no fix?

Resistance to ground on ppvrtc?
I would check U2600 and the 4 capacitors on the ppvrtc rail.

i get 33ohms resistance to ground on pad 1 of u2600. i pulled u2600 and the 4 capacitors and still 0.001 in diode mode.

No, This is a £400 board. Send it to someone who can replace the PCH. Try get a trade rate.

Certainly not a donor, replace the PCH and fix the BIOS!

 

[roy.ruan]

yea tried that before, this PCH is not that hard to replace...then flash the bios with clean ME then you have a 400 board for sale...which is in good demand in the market now

 

[jgraffis]

I'm guessing i would need a reball machine to replace the PCH and there is no one I'm my area that i know of that does that kinda of work. ill look around online and see if i can find some one. thanks.
