@seanyboy check something like [https://www.youtube.com/watch?v=mwAnYR08maQ|this video] Remember that the disassembly may not be specific for your TV but the steps are very similar.
While you work on your TV, 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 the same problem as you do.
