iPhone 5s not turning on

[Glocky92]

Hi I wonder if you have heard of this problem.
My phone has a blank screen and doesn't respond as if it's dead.
When I connect to Itunes, it only recognises it if it's put into DFU mode on iTunes.
I then try to restore it but it only comes back with the error 4005
I have tried a new battery and hard resetting the phone but nothing happens. I have also tried the apple support page. I thought it might be the U2 ic chip just from reading up. But I am a bit of a newb

Hope you can help!

Thanks

George

I think your iphone is bricked and you should take it to a technician, don't risk to loose it by trying things that could work or not.
