Among others, Polytron DIVA PS1423A 14 inc sbb.uCom/Generator: HBT-00-01G, Horizontal: MD1803DFH, Vertical: STV7302A, Audio: UTC2003, Control: FET FOPF-7N65C, Jumper: FCM-20B062N.
Kerusaka.
* Protect, go through the voice channel Sur 2 has it on standby.
Saat On saa ukur semua Vcc normal mulai B+115v, 180v, heating AC 5v then Vcc Vertical CT +12v and -12v.
If you face this problem, don't be afraid to replace the vertical IC because it is a wrong step, but first try to disable the protection button of Polytron using HBT-00-xx ICs like DIVA series, the protection button is enabled. pin 62, but there are only two vertical dengan saranka, normale nilai sekitar 5v, dan yang saya ukur siyaya hanya sebagai 2v, lepas soldan en suntik dulu dengan Vcc 5v, caranya kasih saja R 1k menju Vcc 5v, hidupkan tvla, pasti bisa. lalu langkaye beringearnya beringearnya…
I found that by changing the value of C402 from 3 to pin Boos-up IC Vertical yang tersambung dengan D401 secara seri menguti titik to protect tadi, nilai aslinya 1u50v...pada AVO saya terbaca hanya 0.45u saya terbaca 5unya hanya 0. 8v dan celetah dissolver kembali ke titik Protectnya mendiya sekitar 4.8v... then finally tv bisa bekerja normal!!!!
