iPhone won't turn on after screen replacement?

"From the days of modding the first Sony psp... And making pandora batteries, for magic memory sticks lol ... If you ever cut or damage a conductive line on a board.. You can fix the issue by using a number 2 pencil and the graphite will reconnect the electrical circuit just be sure not to interconnect any lines, however with a digitizer cable punctured this will only work if it's a small puncture as it cannot fix a complete tear in the cable... I fixed a friends iPhone 5s this way after he attempted a screen repair himself ;)

And before asked to specify you sharpen the pencil as pointy as you can get it and then gradually color in the problematic area until a nice very small pile of dust is seen then blow this off and if the circuit is now appearing to be connected with the graphite line try your work and then use your repaired device to thank me :)"

"Try in the following order: disconnect the screen, reconnect the screen making sure all 3 connectors are properly seated, connect the iPhone to a charger or your computer, then reboot your iPhone (press and hold Home Button and Power Button together for 15 seconds).

Try this and let me know if it helped. If not, we can look at other causes and possible solutions."

"Hi, I have a similar issue.

Just replaced a screen on an iPhone 5s and now it doesn't seem to boot up. I get the Apple logo then the screen goes blue and restarts the process again.

Any help massively appreciated

"Mike were do you buy your screens?

Must say I have fixed 1000s of iPhones and never did I once have to restore for phone to work. Obviously there is something wrong in the way you are installing the parts plus blue or red screen indicates the wrong screws in the emi Sheild and tearing traces below the screw holes. Hopefully this is not the case but you might be hearing from your customer sooner than later

"Not sure if this will be of help for anyone. But I had a similar thing happen to my wifes iphone 4. I replaced the old cracked screen with a new one and carefully re assembled the phone back together. Once the battery was connected, I turned the phone back on to see if the screen worked. At this point everything looked fine. Battery was at 16% as well. So i put the phone on the charger to charge over night and it showing showing that it was 100% charged. I didn't think much of this. So basically in the morning once i took it off the charger it died straight away.

Spent all day trying to find forums to help me pin point the issue. Tried charging the phone again and all it would do was turn on with the apple icon and stay on that screen for 3mins before it made it to the main home screen. then after 2mins it would turn off and restart itself. So i had a feeling that it could've been a battery issue. The battery itself i'm pretty sure was long due to die.

So i managed to figure out what the problem was. I took my iphone and I decided to try my battery in my wifes iphone and took her battery from her phone and tried it on mine. Turns out that my battery worked fine on my wifes iphone while her battery didn't turn my phone on. So the issue was a dead battery.

So with the battery that wouldn't work...i took a closer look at the ribbon connector and it look like it was bent to the point of breaking off. So if you think, you put everything back together carefully, then I would check the battery to make sure that the ribbon connector isnt damaged etc."
