Hi!
I have Macbook 820-02020 without any damage and have just 5v and cant turn it on
When I use A port I have 5v and 0,13 to 0,40 A and I see hot UF400 and UF500 in thermal camera
When I use another port, just have 5v and 0,13A and hot only UF500
Can I change only one UF500?
I've changed redriver and no change . Port A has 5V but doest work with data
U3200 I checked again...
I tried to compare both ports and I saw the difference with D+ D- between work's port and doesn't
Hello! I had re soldered U3200 and got 20v and all are ok! Thanks
But today customer complied about data. One port has no data (no devices work), but charger complete works.
What does it mean, which line for the data?
Hello! Need you help ASAP 😭
I have Macbook 820-00840. one port didn't work and i found short on R3450 . I have changed U3200 and now I have only 5,2v 0A on both ports and it reboot each 2-3 sec
No liquid damage and any problem. I changed C3215C00 and have no charge on both ports now
Thank you! I was. So
I don't have PP1V1_UPC_XB_LDO_BMC for both ports and strange with PP3V3_UPC_XA_LDO and PP3V3_UPC_XB_LDO
I have got PP3V3_UPC_XB_LDO is 2.2v and PP3V3_UPC_XA_LDO is 3.3v for one port
And PP3V3_UPC_XB_LDO is 3.3v and PP3V3_UPC_XA_LDO is 2.2v for another
Hello everybody !
The charger is stuck at 5V - 0amps.
PP3V3_G3H gets dragged down to 2.26v for an unknow reason. If I remove the resistor R6999, pin 1 gives me 3.4v. Resistance in diode mode (red probe on ground) on pin 2 is 0.395 and another way (black probe on ground) is 0.822
I've tried...
