iPhone 4 replacement displays not working, any suggestions please?
I'm having trouble with new display assemblies on an iPhone 4. I've tried three from two different suppliers and they all stay blank when I try to switch the phone on.
- The phone works fine with the original (smashed) screen reinstalled
- iTunes recognises the phone ok in normal and DFU modes
- The backlight does not come on with the new screens
After a lot of internet searching I saw a comment on iPhone 4S Display Assembly not working with iOS smaller then iOS 6 and decided to try booting up with the old screen installd and hot-swap to one of the new screens.. The two new screens I have here still both work fine with this method but only until the phone is switched off!
Can anyone help please, what is going on and how do I fix it?
Is this a good question?
