White Screen after replacing glass+digitizer
I replaced glass+digitizer on my Iphone 4G, separating LCD from original broken glass+digitizer
Now I have white screen when I power-up Iphone, I can't use the phone. I don't understand because all the connectors are fit in correctly, I followed all the guide in 20 steps with correct removal tools. I tried also to push all connector on main-board during powerup, but there is no any difference.
My doubts are:
- If I damaged LCD internally or externally on flat-cable during operation of separating from glass digitizer, can I have white screen?
- Or maybe was it necessary remove also the black "paper" together LCD from glass digitizer ?
From what depends the white screen in power-up? Any ideas?
However I will try to replace again all using assembly LCD+glass+digit
solved. it was lcd damaged because i changed all the unit and now all works good.
Sounds like a damaged LCD ribbon cable. I would never try and seperate the LCD from the digitizer on an iphone 4, you are just setting yourself up for heartbreak. I tried it once, took me an hour when I got 3/4 of the way through I cracked the LCD. Not worth it. I would suggest buying an all in one unit and starting again.
