kerusakan tv polytron ic HBT-00-04G :
A. regulator ic501 7N65 dipasang
start langsung konslet
cek/ganti : - D518,D521,D519,D530 - elco C522
100uf/400V - D514 2V7 - T508 A1015,T509 C1815,T507 C945/C1815 - ic 502
PC817/opto - ic 504 TL/WA/KA431
B. gambar blur pelangi
cek/ganti :
-
R417 1 ohm/-12V FBT
- D407 VCC-12V
- ic 401 STV9302
C. garis2 pelangi
layar atas tv
cek/ganti : elco C408 100uf/35V
D. gambar garis mendatar
cek/ganti :
- C303 104 pin 15 ic HBT
- D403 IN4002/4007 dioda pump up
-
ic 401 STV9302
E. garis berdiri
cek/ganti :
- solderan socket yoke
horisontal
- C801 560N/250V
- L801
- yoke horisontal
F. TV susah start
cek/ganti :
- C 503 1000uf/25V
- C505 47uf/63V
- C510 10uf/50V
C512
10uf/50V
cek juga sumber utama supply 5v 220uf/25v
G. tegangan output acmatic naik turun
cek/ganti :
- D511 IN4148
- D523 IN4148
- ic 501 WA/WL TA 431
- C503 1000uf/25V
- T506 C1815
H.
R517 180 ohm terbakar
cek/ganti :
- T505 A1023
- D512 5V6/zener I.
gambar putih polos tanpa OSD/display cek tegangan 5V dari kaki emitor
T504 C2236 biasanya drop karena D512 short dan R517 terbakar/ganti.
