Proximity sensor fail after screen replacement?
I recently replaced a digitiser and LCD in an iPad 4. The repair was successful - until a month later the client has came back to me and there's no display, it's responsive to iTunes so it is not dead. I can only think of the proximity sensor? It's just a black screen.
Where abouts is the proximity sensor located and is there anyway of just disabling it so the display can work again?
Thanks in advance.
Is dit een goede vraag?
