Blue Screen After Putting It Back Together

So I've taken apart my iPhone 4s a few times now. The first was to replace a battery and vibrator, the second was to replace the audio cable, and just last night I went in there again because the silence switch had stopped working.

I've been super successful with these repairs; everything has gone off without a hitch, but last night when I put it together my phone screen was blue.

The phone actually still works. It's apparent I can navigate through the home screen by swiping left and right. It's just really fuzzy with those blue and white lines in the second image. Opening apps is trickier to judge, but I can use Siri to call my wife. So the phone isn't busted, it seems like just the screen.

Does anyone have any idea what might have happened and how to fix it, short of buying a new display or logic board? I've been successful taking this thing apart and putting it back together a few times now. I can't think of anything I could have done to damage anything. Thanks for any advice!

I'm going to go with ribbon connector has become damaged for the LCD display. You will probably have to get the screen replaced.

You can get the part from here, otherwise order where you wish:
