No display after screen replacement

My iPad had a cracked screen with severe LCD damage where all could be seen is lots of colored lines. I got a Apple Original screen to replace it and when I installed the new screen and hit the power button all I get is the backlight (no image just a black dim screen) for about 3-5 seconds and then it turns off. I transferred my home button to the new screen and it works fine as I am able to put the device in dfu mode with it and force restart. when plugged into my Mac it doesn't show up in finder until I put it in recovery mode or dfu mode. when restoring it gives me an error 4013. when I put the damaged display back on, it restores without a problem and works as it should other than the damaged LCD. I don't see why the new screen isn't working. Any help is appreciated!
