I replaced a non working LCD and digitizer with a new LCD + Digitizer assembly but it still does not work. The repair went smoothly and without issue. The phone powers on, the speakers work and the buttons work, but I still do not get any image from the LCD. I own a small business doing computer and mobile repair and this is the first time I've had this problem. This repair was for a client and now I am very anxious. I am searching everywhere for help.
