Sir,my name is Suraj. I have a mi mobile. One day it fall in water. So it was off. I took it to the service center but they told me change all motherboard. Then I gave it to my friend. He told me that only display light does not work. Because the IC is damaged. He returned my mobile. So please sir tell me what I do,because the center did not give proper solution.
Disassemble the Phone and clean the motherboard, all the connector and all soldering points with IPA using a Brush. You can buy IPA Solution and any Shop where they sell mobile phone parts. Clean properly everything and allow the IPA to Evaporate and dry up. Assemble back and check. Give a boost to the battery using a battery booster if required. I think it will start working.
