madaming way para ma check mo kung bakit nag shushut off
mag visual check ka muna kung may makikita kang obvious na
burnt parts or open fuses, kung ok naman pwede ka mag check
ng voltages bago siya mag shutoff malalaman mo na agad.
or pwede ka direct testing naman ng output transistors basta
make sure na discharge mo muna mga cap.
be safe pag dating sa mga caps hehehe

yun na nga ang problema ko cguro, kasi nung nagdischarge ako ng cap mukang nadamage eh, tapos ala ako makita na same rating, 15,000mf @ 63V, ang gnamit kong replacement ay 10,000mf @ 63v, mukang yun cguro ang nagcause para bumalik sa standby mode, tama ba ang pagkakaintinde ko?
