Dropped iPod, touch screen doesnt works, screen is black, sound works

Today i dropped my refurbished ipod touch that i got around 2-3 months ago, from my desk, approximately 2.5 feet above the ground, onto a carpeted floor. Upon impact, the ipod opened. The screen came off of the other part, but they were connected by a chord. I looked up pictures of the inside of an ipod touch gen 4, and nothing seemed out of the ordinary. However, the ipod's screen was completely black, and the touch screen did not work. when i pressed the home and sleep button simultaneaously, the ipod made a screenshot sound and when holding down the home button, the sounds of voice control were present. Other sounds from commands worked too, such as connecting it to a charger. I could even turn on music with the voice control feature. Upon putting the screen back on, i caused a small crack on the upper screen. I doubt this has anything to do with it, because the screen wasnt working before the crack was generated. I have no idea how to fix it, or where to bring it to get it fixed, and i dont have a warranty, so im in a bad situation. Any ideas on how to fix it?
