nabuksan mo na ba ang charger na yan?

try to check to output from the main board ng charger kung my output siya.
kadalasan kasi wire lang ang my sira walang continuity..

sa circuit part, sa self-oscillating type (no IC used like sa mga mumurahing charger) flyback charger/smps, ang madalas masira is yung primary switching element (e.g. high voltage FET or BJT)..
and kung may ginamit na IC, possible na sira na rin yun..
