Now let's check this mobile step by step :

Krish Mobile Training Institute

• If you connect the 6 in 1 charger to this mobile, it will take 0.1 milliampere .
• When connected to the computer, the port does not take anything
• If port is taken then the solution is different.
• If the connected to the dc power Supply and the trigger is pressed, it will take a reading of 0.145 and it will struck on.

• For these reasons what we know is that the cpu was shot.
• If cpu is good, it will take a port in the computer.
• Remove the mother board from the mobile.
• If you look at the mother board, this mobile water may have been damaged, otherwise another technician may have added Flex Paste.
• It took a little bit of rustling near cpu.

Let's solve this problem in mobile :

• Let’s reball the cpu and make it refix.
• First, cut the glue around the cpu.
• Add the flex paste and slowly lift the cpu with the lifting blade while slowly heating it with the Blower.
• This is qualcomm cpu.

• After lifting the cpu, the led should be cleaned with a soldering iron on the ground.
• Then show the heat and clean the black paste with the lifting blade of the cpu.
• Add flex paste and clean it with a wick.

• Now let’s clean the cpu.
• cpu should be placed on the PCB board.
• Apply flex paste on top of the cpu and clean it slowly with a lifting blade while showing heat.
• Then clean with a wick.
• Now we have to rebel cpu.
• We are taking the cpu stencil to reball the cpu.
• Keep the cpu stencil on the cpu without moving.
• Apply some ppd paste on the stencil and heat it with a blower.
• After confirming that the reball is correct, the stencil should be carefully removed.

• Now let’s fix the cpu to the board.
• After doing the refix, attach the mobile to the mother board.
• After attaching, connect the charger to the mobile and check whether the mobile turns on.
• Mobile turned on successfully.
• problem is solved .
• customer is happy.
