2nd step: try to test all power section malapit sa charging terminal, SHORTED lahat ng parts sa banda sa charging at no output voltage sa 20volts MORFET IC...
3rd step: try to change MOSFET IC 20 VOLTS no luck...
4th step: hunting again using tester, try ko test mga shorted diode,smd capacitor, resitor
https://postimg.org/image/husg64gvx/5th step: huli ang salarin OPEN ang palo nya sa tester ung may bilog un ang defective...
