My iPhone 4S screen won't turn back on

I dropped my iPhone 4S and now the screen won't turn back on but I can still hear Siri and calls being made to me and all that? I took apart my phone and installed another completely new screen and its still doing the same thing! How do I fix this?

You might wanna just restart the phone to factory settings if that does not work I would suggest a new phone

You could try turning it off or plug it into the charger… If that doesn't work I would bring it to the store where you got it and see what they think.

Shouldve went with a more reliable phone. BlackBerry.

Have you tried the hard resetting process of your iPhone? Like all computers, sometimes iphone needs a reboot.

This is how to do it.
1. Press hold the home button simultaneously with the sleep/wake button on top of the phone.

2. Continue holding it until the phone shuts off and restarts.

3. Release it once you see the Apple logo.

4. Just wait, don't panic if the screen takes awhile to load. This is normal.

But please keep in mind that it is still best not to reboot your iphone. If turning it on and off is allowed, choose this option instead.
