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 this a good question?
