IPhone 5s Display Light Solution Backlight Ways Lcd Jumper

The most Apple iPhone 5s phones come with the Backlight is not working Problem. Therefore, we are provide a new way solution to fix the Backlight problem. Our new way solution to install on your phone, no need to remove or heat your phone Backlight area ic,coil,transistor spare parts because the solution is a Jumper way planning. so we hope the solution will be Easy to you and we’re completely tested, it’s exactly working.

Step 2 -   Check LCD Connector (J5)  pin no. 17,19,21 ( Cold Testing & Hot Testing)

Step 3 - If Track is open than find ( FL24,FL25,FL26) Make it jumper. 

Step 4 - IF Coil is ok than check ouput supply of Light IC ( Diode - D1) 

Step 5- If Track is ok but Voltage is not proper than check Boost Coil L3  ( Near Boostcoil) 

Step 6 - If Booscoil is ok than change Light IC ( U23)

How to Make a Jumper in the Socket Display
Prepare a cable smooth and adjust the length that we will connect its tracks
Heat Tin with solder for attaching fine wires so that it will closely united.
Use a voltage tester to measure the jumper cables.
