Help Display not working

[jibss5]

Hey all. My display isn't working. I am guessing something is fried. I ran over the end of my charging cable with a roller computer chair. One of the little nodes on the charging cable that plugs into the tablet was bent. I just bent it back in hopes of not having to get a new charger. It worked for a while. Then my keyboard battery stopped charging. Now the screen doesn't work. I plugged it into my TV and the touch works and everything is fine. I tried factory reset. I opened it up to check if all the cables are plugged in properly to the screen and motherboard. Everything still black. I think I have to replace the screen but want to make sure before I buy a screen and switch it out. Any suggestions?
