If in Reverse Checking Value is 350 then there is Half Shorting. If Value is SAME in Both Forward and Reverse Checking then there is Half Short.
How to Check Full Shorting
If there is BEEP Sound in Both Forward and Reverse Checking then there is Full Short. If we connect Positive ( + ) and Negative ( – ) of the Battery Connector to a DC Power Supply Machine and Amp Starts to Decrease without Switching ON the Phone, Then there is Full Shorting in the PCB of the Phone.
Solution to Fix Shorting in Mobile Phone
To Fix Half Shorting, First Step is to Disassemble the Phone and Clean the PCB Thoroughly with IPA Solution and the Apply Heat All over the Board using Hot Air Blower Machine. Assembly Back the Phone and Check if the Problem is Solved or Not. In Most Cases the Problem gets Solved. But if there is still Half Shorting then Check for Tiny SMD Capacitors Near the Battery Connector. Remove the Faulty One. In case of Full Shorting, Connect the Positive ( + ) and Negative ( – ) of the Battery Connector to a DC Power Supply Machine. Amp will Start to Decrease without Switching ON the Phone. This means there is Full Shorting in the PCB of the Phone. The Faulty Component will get Heated. You can feel the Heat of the Faulty Component with your Fingers. This Component needs to be Replaced.
