Do I need to replace my entire display?

Not exactly sure how it happened, I was traveling and had this laptop in a backpack with a cushioned laptop sleeve and took it through the airport. A couple days later I got this grey screen. I bought this laptop about a year and a half ago from a third part reseller (B&H Computer) brand new and it came with apple care. Well, now the warranty ran out so I am out of luck trying to get apple to replace it without paying a large sum of money. Some third party "We fix apple product" shops have also quoted me about 425$ to fix it. If I have to replace the entire display I will do it myself, but I wanted to know if there was anything I could attempt to do first.

One thing to note. It seems that the grey bar is changing color randomly, sometimes solid grey and sometimes it is grainy and you can see some of the display content in the bar.

Thanks in advance!
