Hello friend, I have a TV like that and the SMD transistors were also shorted, the problem is that I changed all those that were short, now turn on the TV but the YSUS card makes a noise a bit annoying, the noise is like the sound of switching at high frequency, there are some strange screen pixels and then they look good, I notice that the YSUS card is not working correctly apart from the card they get quite hot. Could you help me?
The possibility that what is called a strange picture is like red spots. If so, yes, it's not normal. It's possible that in the short transistor area there are parts that ask to be replaced, such as the smd resistor or even the aici driver
@@hadycjdw Thanks for answering, yes there are some pixels that seem to turn red, after a while it is removed, sometimes they come out, check all the SMD resistors that activate the transistors What is the aici driver? I have checked the oscillator (the optocouplers are correct) but I don't know what the aici is. You mean the IC VHC T541A?
Do fet 7n65 gk ada tegangan..coba out vhct ada tegangan tidak.atau inputnya lewat out vhct..makdusnya yg di kasih tegangan 3vol out vhct ada gk teganganya di pin gat 7n65 kalau gk cek lagi r 15ohm
Sebetulnya kalau di urut 1/1 input ic driver yg di kasih teg 3v..namun vhct tidak usah di paksa nyala.kalau di input p155e di kasih teg 3v outnya harus ada yg ke pin gate.kalau gk ada p155e rusak.. Kalau vhct di paksa nyala di pin input p155e harus ada teg 5v
Sangat membantu bagi pemula,terimakasih telah membagi ilmunya sangat bermanfaat untuk kita semua.sehat selalu bang...
Maturnuwun ilmunya kang..melu sinau.
Podo podo sinau kang
Soko blog
Fb youtub 😁😁
Buat juga video test external 50pa4500
klo suntik teg 3 vol ke IC vhct 541 di kaki berapa om utk mngaktivkan teg gate igbt
Pin 2 sampai 10
Pin 2 sampai 10 di suntikan tegangan 3 volt semuanya kang
Mas untuk pin 5V, kaki IC 541 yg no brp ya??
Itu cukup satu kaki input 5V untuk semua pin IGBT??
Kalau ikuti cara saya 5vol nya udah dapet dari sumber utama.pin 20 coba di cek
Bang punyaku baru di kasih tegangan gate udah nongol padalah blom di perintah di ic yg menuju tcon

@@hadycjdw ?
Yes aici vhc t541a
Klw cekny semua pin Igbt dan fet terpasang gk ap ya?
kala service ysus kayak gitu kena berapa om..? soalnya punya saya tegangan 18 volt pada ysus gak keluar typenya sama..
400ribu bisa tuker tambah atau servis
Cuma kalau teg 18vol bisa jadi bukan faktor di ysus saja
@@hadycjdw dekat ic yng di ganti kyaknya ad yng jemper , yang mana yang d jemper bos
kalau dicek tegangan seperti itu terus tidak keluar tegangannya apa sudah pasti VHCt541 yang rusak dan harus diganti?
Bisa di urut.out vhct juga sebelum ic driver ada teganganya .
@@hadycjdw di fet 7n65 tidak keluar,, di igbt rjp36k2 keluar sekitar 9volt,, apa sudah pasti ic VHCT yang rusak_?
