820-00281-10 5.24v 0A

[bartech]

i got 820-00281-10 , stop working , on all usb i got 5,24 0A no water damage.

What about PPBUS_G3H and 3V3_G3H?

 

[bartech]

ppbus_gsh - 0V
3v3_g3h - 0.51v

 

[2informaticos]

Remove both F7000/1 and check C7050 coltage.

 

[bartech]

0,07v

 

[2informaticos]

Post U7000 basic voltages: P_IN, AUX_DET, SMC_RST_IN, VDDA/P, EN_VR1, SMC_RST*, AUX_OK, A/BMON.

no battery

ppvin_g3h-0
aux_det-1.28v
smc_rst-0,45v
tba_vdda-5,07v
tba_vddp-5.07v
hpwr_en_l-0,44v
smc_rst_l-0v
aux_ok-?
chrg_amon-0
chrg_bmon-0

 

[2informaticos]

"ppvin_g3h-0"
In fact is PPDCIN_G3H_CHGR.
Are you sure it is 0V?

 

[bartech]

sorry i check something wrong,
its 5.13v

 

[2informaticos]

"aux_ok-?"
Doesn't have a value for it?

Try changing U7000.

 

[2informaticos]

What about SMC_BC_ACOK?

How did you find the other lines???

 

[bartech]

all usb c after change 5.23 v 0.02A
smc_bc_acok 0.27v

 

[2informaticos]

Still no voltage at C7050?
In such case, check diode mode to ground there.

 

[bartech]

0v
diode mode - 1301

 

[2informaticos]

Post resistance (ohm scale) over C7020/23.

 

[bartech]

c7020-3,2
c7023-4,2

 

[2informaticos]

Post again U7000 voltages, above mentioned.

 

[bartech]

u7000
ppvin_g3h-p3v3gsh - 5.16v
tba_aux_det-1.31v
smc_rst-0,27v
tba_vdda-4,98v
tba_vddp-4,98v
hpwr_en_l-0,19v and risingstop at 0,36v
smc_rst_l-0v
tba_aux_det-1,29v
chrg_amon-0
chrg_bmon-0

You've always missed EN_VR1, why?

 

[bartech]

i dont know whitch is it, i dont see anythink like that on boardview .
you mean PM_EN_p3v3_gsh ? -2.06v
