The phone fell on the ground and wont turn on
So, some months ago i was using my iphone 5s when it fell flat on the screen. It never turned on scince, luckly i got a new (used) 5s and i left the old one forgotten in a box. Now i found it and i feel like i want to fix it, so, any ideas? Also, the upper part of the screen separated from the phone. Not completely, but enough to create a gap. I've already opened up the phone but cant find any broken or disconnected connectors. I'm not in a hurry to fix this phone, i just want to see it working again. Thanks.
Is this a good question?
