Ang nangyari po dito ay pag nai saksak sa outlet na 220 or 110 then power on nag oscillate naman po xa tapos makikita mo  na ayos ang display may osd tapos biglang nag shutdown xa sabay continues blink nang timer led.

syanga pala pag shutdown ba nito may secondary voltages ba kumpleto,o wala? observe b+ kng may pagbabago bago magshutdown..baka regulator pala sira nito..

maghanap ng tranie around flyback kung meron  ,tutukan collector kung may output bago magshut down,kung wala nasukat palitan na yan feedback yan galing flyback ovp yan.
