Screen won't turn on while device is on

I was removing the back case on my nextbook flexx 10 to try a solution because the tablet wasn't turning on from sleep mode. I believe I may have touched something incorrectly because now I have the device connected to my TV and it's on, but the screen is off completely. I've seen replacement digitizers but I'm not sure what part has failed. Anyone that has had this issue or is familiar with this, I would greatly appreciate any help.
