HOW TO TEST / CHECK, BLOCK ( Ymain ) TV PLASMA SAMSUNG43 " WITHOUT MAINBOARD # k4ry4 4Die

HOW TO TEST/CHECK THE BLOCK (Ymain) SAMSUNG 43" PLASMA TV WITHOUT MAINBOARD#k4ry4 4Die, to test whether this Ymain block is in good condition or not, we can check and test by giving a 15volt teg which is taken from the 15volt teg from the power supply to be connected to several points like the following, at the jumper point (J33) we jump to the + elco (C502) point then jumper to the + elco (C5058) point. These 3 points are given a 15 volt voltage for the ground to be equalized, then we connect the 5 volt voltage from the power supply pin to the pin 24,25 in this ymain block where pin 24,25 is in the flexible socket dr Tcon, after everything is connected we can check the voltage,, if normal in this main y block, then the voltage in drain2, igbt and mosfet there will be a voltage ( see schematic

Mau tanya Guru...
Biasanya ketika pegang tv plasma dibawah 50 inch kita focus terhadap tegangan VA dan VS pada modul Y & Z main board nya.
Kali ini saya mendapati Samsung 50 inch dengan IGBT sudah aman, namun ketika dinyalakan tegangan VE naik hingga 110v yg seharusnya di panel tertulis 80 lalu teg VA dan VS drop
Solusi dong guru

Ijin tanya master saya punya Samsung ps43e tegangan vs va drop kalau y main di pasang

mhon maaf br bs blas,,kerusakan Ymain kebayakan mosfet IGBT,coba cek lebih teliti satu persatu di mosfet igbt,soalnya igbt shoot sedikit berakibat teg drop,ganti juga elko2 yg sdh turun nilainya dan ganti juga kapasitor2 milar dgn nilai1kv warna biru,klau gk mau di ukur/tes ganti smua 1kv,coba cek resistor 2,2ohm,di area mosfet igbt,perlu di ingt klo ada pergantian igbt blikan yg asli jgn yg kw klo ada kanibalan lebih bagus karena mudah rusak ,,teliti dan fokus di igbt jgn cek hanya di satu igbt cek semua dgn teliti,pastikan klo sdh ok sblm di coba ,harus dipasang semua baut sekuat mungkin jgn sampai longgar karena hentakn grounding di tv plasma bisa berakibat igbt menjdi shot,,jgn sampe soket2 yg dr power suplay ,dan Y main longgar paskn semua sblm coba,,cek juga di bagian power suplay terutama elko2,jgn ketipu fisik msh bagus harus betul2 di ukur kapasitasnya ,mengingat tv plasma tv lama,,dan sangat sensitif di teg turun sedikit bermasalh,jgn kesusuh utk di coba cek secara teliti ,,trims tlh menyimak,,mhon maaf klo kurng detail krn gak megang fisik,,
