Replaced entire screen but I got white screen.

So the other day I dropped my phone on a little bit of water and the screen went black and the vibrator wouldn't stop. So I opened it and disconnected everything let it dry for a couple of hours and put it all together brilliant it worked for about a week when my home button and wifi weren't working so I decided to open it and see if I disconnected something on accident. I blew the dust off and screwed everything together again but I guess something broke and my sreen only showed the colors in like the apple logo were grey and white lines in the middle of the screen up and down. I got really worried so figured I broke the screen, I bought a fully built screen in amazon and decided to repair it my self since I'm out of warranty. I then put it all together but when I turned it on nothing showed it was all black then I heard a little vibration so I clicked the home button and baam it was just pure white. I restored it on itunes and nothing still had that white screen. Please help I'm running short on money and would really like to have my iphone back for christmas.
