Distorted image after digitizer replacement

My iPad screen cracked and I got a replacement digitizer. Unfortunately after going through the whole process of replacing, I realized that I had left the iPad turned on while replacing the digitizer (i.e. disconnecting and reconnecting LCD, digitizer, and home button). Now, the screen just displays white with a grey line across the screen. I'm positive that everything else still works as it still locks and behaves as expected. Anything I can do before I try to reseat the LCD connectors?
