    mohon bantu analisa para master, bb 9700 awal masuk matot. cek ketemu short di vsys, suntik tegangan ada bau hangus sebentar lalu short hilang, tapi gk tau komponen mana yg hangus. pasang baterai hp nyala normal, done. 3 hari kmudian user balik lagi, matot lagi. cek vsys short lagi, injek tegangan amper naik 1.50 A. copot ic power, copot jokus lalu injek tegangan masih short tinggi. di raba2 muncul panas merata di plat kuningan dibalik soket kamera. sekeliling soket kamera di kasih flux merata, lelehnya juga merata. jadi gk tau komponen yg mana pnyebab panas.
    lalu cuci bersih flux, injek lagi (agak jengkel...) kali ini dgn tegangan agak tinggi 4v. muncul asap sebentar di sekitar soket kamera. tapi tetap gk tau mana yg hangus. copot u1604, tetep short. karena puyeng, hp smentara di masukkan laci. besoknya coba cek lagi, ee.. short hilang. pasang baterai, hp nyala normal. 2 hari user balik lagi, lagi-lagi penyakit sama. bongkar, injek lagi vsys amper naik 1.5 a sbentar lalu normal. begitu terus berulang2 sampe user balik 4 kali. kapasitor sudah di buang semua, tiap hp mati injek vsys sh0rt sbentar lalu normal. mohon bantu analisa master..
