    Dpt pasien BB9900 kondsi matot....
    Kondsi awal :
    1. Cek pake PS = 0 (ampere tidak bergerak)
    2. Cek pke AVO di jalur Vbatt, tidak ada yg short

    Yang sdh dilakukan :
    1. Cuci pcb
    2. Cek pake PS..ampere cm naik 0.06mA
    3. Cek titik ukur Jet power = semua tegangan kluar normal
    4. Cek di titik ukur IC power = C1228 hnya kluar 1.2V (harusnya 1.8V...CMIIW) --> vreg_msm_C1
    5. C1241 = 1.23V
    C1228 = 1.2V
    C1247 = 1.78V
    C1236 = 0V
    C1232 =0V
    C1233 = 1V
    C1243 = 0V
    C1240 = 0V
    C1272 = 0V
    6. Vreg kebnyakan ga kluar/lemah tegangan.

    Hp ttep ga nyala dan ga detect di komp...LED jg ga nyala..

    Mohon bimbingan...

    Matur tengkyu....
