Why I can't turn on my phone but it's vibrating

try to move your battery left or right or down than try to turn on your mobile phone

Hi ,

If the vibration is working that's mean your phone is power on and working , you have problem with the display, first try a hard restart hold home and sleep buttons for 10 seconds until you see the apply logo again, if nothing change it seems like an backlight issue, focus on you display in a dark room if you still don't see anything, then you should be happy, that's mean nothing wrong with your backlight chip, you need a new screen or just replug the screen connecter can fix your problem

Let me know ,
