Hi, got an 820-02016 with bad sound on left speaker.
Tried 2 other speakers, no change.
SPKRAMP_A_OUTP, SPKR_ID0, SPKRAMP_A_OUTN diode mode test the same as good board.
Replaced UR600 just in case, no change.
I looked for diode mode LDO readings on CD3215 chips and found that PP1V1_UPC_XA_LDO_BMC on U3100 is .0l
While on U3200 PP1V1_UPC_XB_LDO_BMC diode mode is 0.45
Could this be an indication that U3100 is Bad?
i replaced Q3200 again.
Theres continuity between CB212 and Q3200. CB212 is not shorted.
Theres also continuity between Q3200 and F3001.
F3001 has continuity on itself and with C3201.
The only difference i could find between the ports is on the DGB lines, which connect directly to U3000, that are not present on the right side ports.

I determined the...
Hi, i have an 820-020020 that does not turn on and i need to find its serial number to check if its IC Locked, so i know if its worth to repair it. I dont have the original chasis, only logic board and touch ID.
Printed in the motherboard it has the following code: C02109401VFQ8LN1Q , but it is...

Hi, i got a 820-00850 with no camera, OS says camera not detected.

Got an U8250 from another board of the same model.
Now i got both SENSOR_PWR_EN and PP3V3_S4SW_SNS but still no boot.
Tried DFU but it gives error "AMRestorePerformRestoreModeRestoreWithError failed with error: 9" when installing system
