What's wrong with my iphone

My phone screen shattered and when I got it fixed they told me that there was a bunch of internal damage. The components fell apart as soon as they did anything to the phone and I decided to replace it completely.

You probably damaged a component required to turn the phone on and unfortunately, you can't figure out what is damaged until you remove the screen and see what's broken.

You should try to restart the phone again by holding the power and home buttons down for at least a minute. If that doesn't work, try to get the phone fixed by a professional. If you do decide to get it fixed, expect the phone to have a lot of internal damage that needs fixing.

yesterday I dropped my iphone 5c on my bathroom tile floor and the screen popped out a little and the home button was pushed it, I pushed the screen and home button back in and it was back normal but my screen was blue/black. Through all of this I was on the phone with my friend and after u dropped it she was still on the line. I figured it wasn't too damaged

since she was still on the phone so I then started to restart it by holding the lock button and home button. When I did this it turned off and didn't turn back on, I tried putting it on the charger but it only vibrated every 10 seconds. I think the LCD is damaged and I need a new one because something similar happened like this to my phone bot too long ago but I wanted to make sure that it wasn't damaged more because I tried restarting it.
