Hi, I have a board with no power, Draws 16-17mA
ppbus_g3h = 12.6V
U7201:
3v3s5_en =3.4V
pp5v_s5 = 5V
p5vp3v3_vref2 = 2V
3v3s5_comp2 = 1.8V
P3v3s5_VFB = 1.1V
It seems all the 3.3 Rails are coming up short, am I right?
Hi, I was to preface by saying I do not know how these newer boards work.
I had a cap that blew and I replaced it on this board, I do not have the schematics so I can not say specifically. I have attached a picture of the cap though.
Connecting this board to a USB-C meter it successfully goes...
Hi again, I have an A1502 board that started at 26mA for a while, I was testing voltages and at some point, it jumped to 150mA
I was originally missing PP5V_S4 on L7520 but then once it jumped to 150mA it was present.
L7320 & L7310 seem a little low at 1.7V instead of 1.8V?
U1950 there is no...
Thank you for the welcome. it really does not power on, I was using a dc power supply connected to a usb-c end with 20V going into it, then I removed it and hooked up 1V to the g3H line and it draws insignificant amperage 0.007A
Hello,
USB-C meter does not power on, board appears bone dry
CD3215 chips both produce 3.3V and no unusual heat under thermal camera
injecting 1-8.6V into ppbus_g3h produces no amperage
D6905 Measurements:
1) 500mA -> Slowly decreasing (PPBUS_G3H)
2) 100mV -> Stable
please help me I'm...
