IPad screen turns on after reset, but not after screen sleep

I just recently replaced the iPad LCD on my iPad Mini 2 and got it working thanks to another person on here. After the repair everything seemed to be going pretty well, up until the point that I pushed the button on the top of the iPad to turn the screen off. I went to turn the screen back on and only the back light was responding. If I wanted to see the screen I would have to soft reset, seven seconds of power + home button pressing, before there would be any information of the screen.

So far the steps that I have taken are:

• Several soft resets
• Resetting all of the settings
• Opening the iPad back up to make sure all of the connections were solid
  

(nothing changed so I can assume this was true)

Currently the iPad is getting backed up, then it will start a factory reset and I am hoping that this will solve the issue, however if it doesn’t I would like to have a backup plan prepared!

Thank you all in advance!

Edit: Finished factory reset this morning still no change.
