Once you have it opened up take a good look at teh boards. Post some well focused pictures of those with your question. That way we can see what you see https://www.ifixit.com/Guide/Adding+images+to+an+existing+question/21499
While you work on your monitor, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
