Member: 573287 Status: Offline Thanks Meter: 0 | one simple way to check the shortage for all phones For automatic power supply(which cuts or reset the power supply automatically to mobile when it is short) ,regulate your volt to zero and apply negative and positive wires to your short mobile phone battery terminal.Now increase the voltage slowly until your supply resets with the shortage of your phone.suppose your supply gets reset or cut the supply to phone on 1.5v.Now adjust your supply to 1.4v (0.1v less) and give 1.4v to your phone.check your phone board with your finger tip which part is heating up.the part which is heating is the reason your board is short.just remove that part and change it and your board will be alive again. usually pa,light coil,light ic and power ic are the reason to shorten the board. |
