Any Help is GREATLY APPRECIATED

 

[2informaticos]

Post some voltages for U7100; 1, 2, 3, 9, 12, 13, 14, 15, 18, 19, 20, 27.
Any history available?

 

[peeka79]

No Liquid damage Not Dropped,...Customer says Battery went dead and that was it...That?s all I know...The Board is SUOER CLEAN all over.

 

[peeka79]

I?ll check the 12 Lines you mentioned on U7100 ?

 

[peeka79]

Here are the Readings from U7100


Pin 1 = 15.86V
Pin 2 = 16.30V
Pin 3 = 0.00V
Pin 9 = 0.029V
Pin 12 = 3.41V
Pin 13 = 3.38V
Pin 14 = 0.00V
Pin 15 = 0.048V
Pin 18 = 0.117V
Pin 19 = 5.50V
Pin 20 = 5.50V
Pin 27 = 0.001V

After checking Voltages on U7100 I have now lost green Light and Lost Previous Voltage on Both Pins of R7029...??

 

[peeka79]

U7000
Pin 1 = 0.000V
Pin 4 = -0.000V
Pin 5 = 0.024V

Also getting 3.4V on pin 5 of 7001...But 0.000V on Pins 1, 2, and 4

 

[peeka79]

Getting 0.925 mOhms on Both sides of R7029 and It is reading properly as a 2.0K Resistor

 

[2informaticos]

"Pin 3 = 0.00V"
Missing ACIN for U7100.

"Pin 1 = 15.86V
Pin 14 = 0.00V"
These are just the result of above mentioned; as missing PPBUS_G3H too.

"Getting 0.925 mOhms on Both sides of R7029"
If is diode medo to ground, you probably forgot to disconnect power...

Check R7110/11 and C7111.
If all OK, change U7100.

 

[peeka79]

Okay Replaces U7100 and Got my Green/Orange light back and SYS ONEWIRE AND BC AKOK is Back But getting 1.09V on PPBUS_G3H, Still have 3.4V in PP3V42_G3H...trying to get the Values for R7110/R7111 and C7111 But I don?t have the schematics for the 820-00426 Just have the Schematics and Boardview for 820-00138...Does ANYBODY have them for the 820-00426?

 

[peeka79]

ANYONE have any Suggestions?

 

[2informaticos]

"trying to get the Values for R7110/R7111 and C7111"
Not needed now.
If you get SMC_BC_ACOK, then ACIN is good too.

Schematic not available, try using 00163.

Post real diode mode on PPBUS_G3H, without charger, nor battery; red probe at ground.

And post again voltage for the same pins of U7100.

Reading On Pin 2 of F7141 PPBUS_G3H 4.40mOhm in Diode Mode With Red On Ground

 

[peeka79]

Thank You 2informaticos for All Your Help. I REALLY APPRECIATE IT!!!...Here are the U7100 Readings on the pins you Requested...

PPBUS_G3H 4.40mOhm in Diode Mode With Red On Ground...

U7100 Readings...
Pin 1. 0.007v
Pin 2. 16.07v
Pin 3. 3.924v
Pin 9. 0.033v
Pin 12. 3.412v
Pin 13. 3.383v
Pin 14. 3.244v
Pin 15. 0.053v
Pin 18. 1.830v
Pin 19. 5.51v
Pin 20. 5.52v
Pin 27. 1.893v


R7186
Pin 1 = 15.86V (Charger_Agate_Div)
Pin2 = 0.006V (Charger_Agate)

 

[peeka79]

I also Measured D7005...
Pin 1 = 16.20v
Pin 2 = 1.04v
Pin 3 = 15.91v

 

[peeka79]

D7005
Pin 1 =16.20V (PP20V_DCIN_CONN_R
Pin 2 = 1.04V (PPBUS_G3H_R)
Pin 3 = 15.91V (PPVIN_G3H_P3V42G3H)

 

[peeka79]

Also L7095
Pin 2 = 3.42V
Pin 1 = 3.41V

 

[2informaticos]

"PPBUS_G3H 4.40mOhm in Diode Mode With Red On Ground"
Impossible to get such reading on diode mode.
Please, set your DMM correctly; diode mode, not ohm mode!
Use manual one, you cannot get confused then.

"Pin 18. 1.830v
R7186
Pin 1 = 15.86V (Charger_Agate_Div)
Pin2 = 0.006V (Charger_Agate)"
Change Q7180...

 

[peeka79]

[No message]

 

[peeka79]

This is the setting I Used with Red Probe on Ground and Black Probe on PPBUS_G3H...With No Battery or Charger connected...Is that Not Correct!

 

[2informaticos]

NOT correct; is on ohm scale.
You must press Yellow button (try Range if not) to switch to diode mode...
