I have changed both the Digitizer and LCD touchscreen, and when i start my phone everything works fine, until the screen switches off (due to normal timeout) BUT then it does not wake up again. And i can see that the backlight or some sort of light is switching on.
What can i do please?
I have tested the proximity and other sensors to no avail.
I have also factory reset and wiped everything from the phone at boot up.
Thank you, and sorry if im a noob!
