LCD Display Replacement / Power issue

Alright, so I opened my iphone 5S to replace the LCD display and forgot about having to disconnect the home button ribbon cable. I ended up replacing the screen and reassembled the phone without a working home button. After having the phone working for 30 seconds, I powered the phone down and reopened it from the top with the mini suction cup. I pulled a little too hard and now the phone will not power on (plugged into computer and emailed myself and nothing) I disassembled/reassembled the entire phone again and found all 3 ribbon cables intact on both ends /no noticeable damage. I tried disconnecting the battery and reconnecting as well. Any idea of the problem? and Is it possible for an iphone to be on and receive calls without a connected display (ripped ribbon cable)

Is this a good question?

Basically I want to know if an iphone can be turned on without a display connected, this would determine if I damaged the lcd display or not

Yes it can be turned on without a display connected. It sounds like you've maybe damaged one of the flex cables or the back light.

Charge your iPhone for 20 minutes to make sure is holding a charge.

Then start iTunes on your computer, then connect your iPhone to the computer. You should see it appear in iTunes, in which case the iPhone is turning on but your display is bad.

If you don't see it in iTunes, let us now to trouble shoot this further.

Good luck.

2 more thing you'd better check: if your display is connected, and you are in a dark room, can you detect any sort of very dim image on your screen? If yes, you have an issue with the back light on the logic board, not with the screen itself. This is not very likely seeing the history of this phone, but it remains a possibility that you can easily rule out this way. AND did you try to hard-reboot your phone with the screen attached? You can do that by pressing and holding Home Button + Power Button together for ~12 seconds.
