LCD Vertical lines screen issue LG G2-- HELP

[lg2123]

I recently bought a new LG G2 on eBay. In the first week, while waiting for a phone cover to ship, I dropped the phone about 3 feet onto the floor Shortly after I turned the screen on to find vertical white and colored lines running up and down the left half of the screen. I installed a new LCD screen and digitizer. The lines are still there, ironically on the other side of the screen now. Please help!!! I don't want the phone and replacement screen purchase to be a complete waste.
