If your device is recognised by a computer, or makes sounds or buzzes but has a blank or black display, then the most likely fault is either the display backlight or the display driver circuit. This can often be caused during a screen replacement, especially if the battery was not disconnected or if the device has been dropped. We will troubleshoot these two circuits returning your device back to life, its a relatively simple repair with a very high fix rate. If you are having touch related issues and have tried another LCD it is most likely to be a board related issue that we can fix.
