INITIAL AND PHYSICAL FINDING.
SAMSUNG CCFL BACKLIGHT PUNDI
MOSFET SHORTED
FUSE SABOG DIN.
Focus sa power supply master since walang power SABOG fuse kaya pinalitan ko. Pero Pag power on sinisibak ang fuse second try pinalitan ko fuse ulit and check mga MOSFET nya sa bandang Backlight section is may leak shorted naka parallel pinalitan ko yung MOSFET still pinutok both fuse at MOSFET .. kaya naisipan ko tanggalin nalang yung MOSFET nya at nilagyan ng fuse ulit yung nag ka power na at di na pinutok fuse.. kaya naisipan Kong mag covert nalang ng Backlight since sira narin yung inverter section ng Backlight
Ccfl convert to led light .. separate Backlight driver module 20 Pcs led light series connection..
May indicator tayo sa backlight driver module saan pwede ikabit yung mga wire basta kuha lang ng 12v para sa supply ng module or VCC nya at ground for ground wire also on/off ..
Results success and running in good condition
Also mas matipid na sya since led light na sya..
