replaced screen - now it vibrates, but won't start up
I replaced screen, now phone will not start up, when i plug it in it vibrates continuously, but screen won't come on. iTunes recognises it. the power on/off button needs replacing, but did not affect operation previously to screen change (screen was cracked, but still working).
I have tried all connections 3 times and can't see anything wrong. I have tried 2 screens on the the first one did not work and i thought it was faulty, so I used another screen, I connected it all up to check the screen would work, before i screwed it all back together, it came on and worked fine, so I screwed it all down and now it won't work, just vibrates when plugged in.
any idea's ??
Is this a good question?
