I guess this means sys_one_wire is not working is this correct?
I am also only getting 8.18V on C7563 PPBUS_G3H, this is low right?

 

[arghhh]

Voltage on pin 5 of U5010?

 

[Modder1]

3.41V on pin 5 of U5010

 

[2informaticos]

Pin 8 of U5010 is high too?
Liquid signs on board?
Check voltage on both pins of R4999.
Y5010 oscillates?
Check if SMC_BC_ACOK is correct.

SMC not running or in bypass mode. If SMC_RESET is high and SMC_ONOFF is high then there is probably crap under it.

 

[Modder1]

pin 5 U5010 =3.41V
liquid signs around U4800 and U9701
Y5010 I think oscillates ever so slightly pin 1 1.5723V-1.5724V pin 2 1.5742V-1.5724V
SMC_BC_ACOK is OL then says 3.1V-2.9 and goes back to OL again and back.
SMC_RESET_L on R7000 3.41V
SMC_ONOFF_L on R5014=4.41V

 

[dukefawks]

4.41V on SMC_ONOFF seems unlikely.....

 

[Modder1]

sorry I meant to type 3.41V
my apologies

 

[dukefawks]

GOTO post #5.

 

[Modder1]

So I should reball the smc?

 

[dukefawks]

Reflow, if no success reball, if no success replace. Or if you are smart and don't want to waste time replace immediately.
