    coba cek Besaran amper dengan PSU 3,9 V .. berapa amper keluarnya ..

    yang dimaksud 0,5A atau 0,05A ??

    kalau 0,5 A coba cek jalur Vsysnya boss, atau buka kaleng Ic Power dan raba bagian mana yang panas ..

    atau untuk meyakinkan jalur Vsysnya, suntik tegangan sebesar 1V naik perlahan sampai 3,7 V di kapasitor C1065 .. lihat perubahan amper di PSU .. kalau langsung

    naik diatas 1 A .. dapat dipastikan jalur itu bermasalah, tinggal cari biang masalah/ kapasitor yang bocor ..
