Xiaomi mi 4 LTE No screen display way

tutorial

Xiaomi mi 4 LTE.

No screen display.

Replace ic 07AA still does not want to appear.

The end of my jumper alhamdulillah successful.

Hope can be useful for other mobile technicians.

I do not write much.

Because in the picture already have instructions.

My post is just a technician who understand the phone.
