kung walang secondary sis baka di gumagana ang reg mo sis or walang triggering na nangyari..Try mo kaya palitan si pwm, kasi ang alam ko pag sira yung fet mo ay automatic palitan mo si pwm bale package mo silang palitan..

paghiwalayin mo master ang psu at main board. tapos short mo ang ps-on sa ground. pag wala pa rin voltage out master. baka sira nga ang pwm ic niya master

 mababa po ang vcc ko baka nahihila ng pwm ic kaya mababa , wala namang mangyayari pong masama pag open ang isa sa power supply diba po? naisip ko hang vcc eh smd kaya mahirap po yung kasunod na pyesa nalang kaya si capacitor po yun

check mo ang mga high value resistor malapit sa pwm nandyan lang ang sira dyan. O mismong pwm na mismo ang sira. palitan mo na lang

para sa akin kaya walang inverter board ang mga led kasi sa aking opinyon ay maliit na boltahe ang kelangan para magana yung screen or ang led nya..D tulad sa mga LCD na needed ng step up trafo or inverter para mapagana..pansin mo siguro sa mga LCD na may trafo..

sorry master hindi ko masiyadong alam. nakakalito kasi sundan iyong tappings ni master. basta naka board na iyon master tapos tatanggalin iyong dating regulator. mag ja jumper na lang ng mga wires. para gumana iyong chopper niya.
