I've had the board out the entire time...... The have been located but they do not have any exposed pins to probe that's why I asked if they are to be removed for testing...

How do I do this? By removing from the board?...Leave a comment:

PPDCIN_G3H checked @ C8122 4.6V
I am using a UGreen 100W charger with a 100W rated cable. Unfortunately the OEM adapter was stolen....Leave a comment:

So I took some time to check the following:
PP20V_USBC_XB_VBUS = 5v present
PP3V3_UPC_XB_LDO = 3.3V present
PP1V8_UPC_XB_LDOA = 1.8v present
PP1V8_UPC_XB_LDOA = 1.8v present
PP1V1_UPC_XB_LDO_BMC = 1.1v present for both CD3215
HV_GATE1 (unable to locate on the schematics)
HV_GATE2 (unable to locate on the schematics)
PPDCIN_G3H = [B]2.8v[/B]
TBA_VDDA = 4.4v
PM_EN_P3V3_G3H = 4.5v
PP3V3_G3H = 3.3v
PP1V2_S5_SMC_VDDC = 1.2v
PP3V0_S5_AVREF_SMC = 3v
SMC_RST = [B]0v
According to the boardview I have[/B]...Leave a comment:

PP20V_USBC_XB_VBUS = 5V @ c3403 (constant only when supplied through the constant port)
PP3V3_UPC_XB_LDO = 3.3V (Only on U3100 when power is supplied through the constant port, on the cycling port U3200 gets 3.3v while U3100 gets 3.25v)
PP1V8_UPC_XB_LDOA = 1.8v @ C3206 (only on U3100 when power is supplied through the constant port but both cycle up to 1.8v coinciding with when the port loops
PP1V8_UPC_XB_LDOD = 1.8v @ C3205 (cycling with the port loop)Leave a comment:

Both are 0.68KOhms checked @ F3000 and F3010 respectively...Leave a comment:

Highlighted is the looping port. Yes I have a thermal camera and voltage injection tool / short killer. Point me in the right direction.Leave a comment:

4.5V constant on the stable port
5V cycling to 2.2V on the looping port...Leave a comment:

I also checked these following a CD3215 boot sequence guide and they are all present:
PP3V3_UPC_XB_LDO
PP1V8_UPC_XB_LDOD
PP1V1_UPC_XB_LDO_BMC
PPDCIN_G3H
USBC_XB_CC1
USBC_XB_CC2Leave a comment:

With charger plugged in to the looping port
PIN 1 = 0.086V
PIN 2 = 1.7V then 5.02V cycling
PIN 3 = 4.7V then 1.7V then 2.4V cycling
On the constant port
PIN 1 = 0.094V
PIN 2 = 0.9V
PIN 3 = 0.8V...Leave a comment:
