Nexus 5 screen responds to touch, but does not display anything.

So about a month ago, I dropped my phone in water. I blew it with a blow dryer (I know this wasn't enough), and let it dry for a few weeks. The screen was already badly chipped when I dropped it in water, some parts of the glass were even chipped. After about a week of letting it dry, I let it charge for 1 hour. When I tried to turn the phone, I felt it vibrate (it always does this when it turns on), but the screen did not display anything. After about a minute, I began to touch the screen randomly to see if it responds. When I touched the screen, sometimes the phone would vibrate. I soon realized that this was me drawing a lock screen pattern. My phone always vibrates when I draw my lock screen pattern, but the LCD did not display anything. I knew my phone was still working at that point. Even trying to get into recovery mode I felt my phone vibrate. I already knew that my phone vibrates when I enter recovery mode. I eventually bought a screen and digitizer replacement for my phone. I installed it properly, and let it charge for another hour. When I tried to turn the phone on, it did the exact same thing! The phone responded to touch, but did not display anything. I even cleaned out the digitizer plug with rubbing alcohol and a toothbrush - didn't do a thing. I know this has to be some sort of bug. Can anyone help me with this? Any feedback is appreciated.
