    820-02016 left speaker issues

    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.

    820-01041 boot issues

    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.
