Pin 13...
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...
Here are Some Measurements
PPBUS_G3H 0.975V with Board plugged in
PPBUS_G3H Diode Mode -0.927V
PPP3V42_G3H 3.4V
PP5V_S5. 0.942V
R7029 (Pin 1) 3.39v (Pin 2) 3.4v
C7505 Pin 1. 0.942V
iSL 6259
4.8 Ohms Between pins 17&18
23.2 Ohms Between Pins 27&28
Any Help is GREATLY APPRECIATED
I Have a Couple more U8200s But I believe your right and there is a shirt on the 3v3_SUS line....any ideas where in the board I should start to find out what?s causing the short?....I REALLY APPRECIATE all your help :)
I replaced U8200 off of a Donor board and when the board was plugged in it Blew out U8200 so I Immediately unplugged the charger and removed the U8200... I am still getting the same measurements as before I put the U8200 on...Here are the Measurments on the pads of U8200 with it off...

Thank You for Your response 2informaticos.... I Just Noticed U8200 for 3.3v SUS Switch is Completely Missing on the Board!! Can I replace U8200 from another 820-00281 Board or a 820-00928 Board? I have Both donor boards here.
Hello, I have a 820-00281 that has No Liquid Damage at all and Will Not turn on...Board reads 19.94V - 10mA to 61mA... Here are some Measurements I have taken with the Board out of the Machine.
PPDCIN_G3H = 20V
PPBUS_G3H = 12.56v
PP3V3_G3H = 3.39v
PP5V-S5 = 5V
PP5V_S4 = -0.00V
PP5V_S0 = 0.012V...
