Nokia Lumia 520 Start Screen shows up but after that No Display
I bought Nokia Lumia 520 recently without bill and now I am having issues with it. When I start the phone, the traditional Nokia Screen Shows up but after that when it redirects to the Home Screen, the display is gone. I tried to Restart it and even tried to pull out the battery and Start again but it does the same. Please help as without bill the Service Center will charge me Money.
