Any idea what else could be wrong?
Edit:
- 5V / 0.16A | PPBUS_G3H = 12.27V
- 19.4V / 0.04A | PPBUS_G3H is slowly going down from 5V to 0V
Did you ever seen such a behaviour?
History:
Water damage (didnt found any signs), one CD3215 area looked like that:
Trace on C3115 to PIN12 was broken, fixed it with a wire (PP1V8_SLPS2R is present):
No voltage on L3500 (P5VUSBC_X_LL / P5VUSBC_X_R) - USB device is plugged in.
5.2V on LB700 (P5VUSBC_T_LL / P5VUSBC_T_R) - USB device is plugged in.
Note: U3500 is getting 5.2V on PP5V_USBC_X_VCC, so maybe U3500 is bad?
Hi,
I have here an A1989 where the left USB-C ports are not recogizing any peripherals - charging is working - right side no issues.
Could it be that the THB IC is damaged or corroded? (Should I reflow the IC?)
Note: The MacBook was water damaged in that area, (U3200 was bad)
Sry for my late reply ....
L9080 = 0.373
L9020 = 0.333
PPBUS_G3H = 12.28V when USB-C output is 5V / 0.16A
PPBUS_G3H = 1.2V when USB-C output changes to 19.4V / 0.05A
Bad ISL?
