HISTORY NG PHONE :
Water Damage
PHONE STATUS :
No Charge sya kpag ina unlock ung phone.
ACTION TAKEN :
1. Chineck ko san banda ung may mga water Corrosion then tinest ko den ung port kung normal voltage nya .. all goods naman ..
2 . May corrosion sya sa may upper part ng board tapos nilinis using brush at ung ibang part ng board NOTE lang bago kau maglinis ng corrosion tandaan nyo po san bandang part un para alam nyo po san kau unang mag ttest ng shorted component ..
3 . Salpak sa power supply then click ung power button .. reading nya not normal .. start ng ampere nya is 200amps hanggang 300amps ..normal reading is 100amps lower kapag press power button .. kaya hinala ko U2IC .. isa kasi sa symtoms ng U2ic problem un ..
4 . Check U2ic using rosin flux kung nag iinit .. pero hnd naman nag iinit ..
5 . Check capacitor around U2ic using multitester tas may line na shorted to ground ..
6 . tas nag focus ako sa upper part kasi dun ko nakitang may corrotion ng water before ko nilinis then connected sya sa line ng U2ic ..
7 . ung second pin ng resistor sa upper part is connected dun sa katabi nyang capacitor
8. chineck ko capacitor using multitester then boooommmmm connected sa ground ..
9. tanggal capacitor tas test unit using power supply then click power button .. reading nya 70amps to 100amps that is normal reading ..
10. balik board then test charging .. viooooolaaaa nag ccharge na sya hehehe
NOTE : wag nyo pong gayahin ung ginawa ko if water damage ung unit nyo .. advise lang po hnd same issue .. same procedure nadin gagawin nyo para ma fix .. troubleshooting po ang key .. salamat po .. pa advise ako mga master if may mga kulang pako about sharing reference on forum .. para next post ko perfect na ..salamat po .. sana makatulong ako sa iba ...
