TV sharp alexander flat
IC 1001 : NXP TDA12110H1/N20D
IC 301 : LA42102
IC 501. : STV9302
IC 701. : STRW6553A
IC 703. : SE125
IC 751. : KA78D33
IC 752. : 050RDA1
IC 851. : TDA6107QF
Q602. : TT2140/TR horisontal
FBT : JF0501-32601/FA132
Kerusakan awal start 2-3 menit standby,cek ricek tegangan pin 3 ic 751 KA78D33 over jadi +5V,normal +3,3/+3,4V,solasi ganti ic 751 pakai Step down,adjust ketegangan +3,41V,tv start alhamdulillah clink

IC KA78D33 disini gak ada yg jual terpaksa pakai step down

Data tambahan :
1. Proteksi :
A. Pin 70 ic 1001 pin protect utama terukur normal +3,37V,non aktifkan protect cabut jumper J495 di sensor proteksi :

- D603 sensor heater akan protect jika C602 4.7uf/50v kapasitas turun,heater drop karena FBT rusak

- D605 sensor B+185V akan protect jika C604 33uf/250V turun kapasitas,R625 180K naik hambatannya

- D607,D608 sensor ABL,akan protect jika R602 39K naik hambatannya,C602 563 kakinya putus satu/kapasitas nol,D607,D608 bocor/short

- D203 sensor B+33V tuner akan protect jika pin B+33V short ke gnd,D201 zener 33V short,R216 39K naik hambatannya,C604 33uf/250V kapasitasnya turun

- D1005 sensor B+5V,akan protect jika ic 752 050RDA1 pin 2 drop dibawah +5V,karena ic rusak atau elco C720 47uf/16V kapasitas turun
- D1007 sensor B+3,3/3,4V akan protect jika
pin 3 ic 751 KA78D33 drop/over tegangan

B. Pin protect V-guard/vertikal pin 57 ic 1001 terukur normal +0,27V,sensor protect :

- D808 akan protect jika ic 501 STV9302 short pin 2 ke pin 4/pin 5 ke pin 4,D505 error,R508 0,47ohm putus

CATATAN
Sebelum pasang Q603........Cek teg Basis Q603....normal HARUS NOL...
kalau di basis 1volt di colector 3.5v
coba di telusuri R614 (100k) yg Terhubung dengan ground bisa Mungkin berubah nilainya atau LANGSUNG ganti R614 .
