This is the board behind the Display/Configuration/mixing switches and is just a switch board.  

Pictures on how to open up the o2r for service are in this listing.  This board has lots of cables so mark your board/cables with a sharpie as to what goes where and take pix before you unhook.  

Here is a demo video of the o2r which also has a close up of the display.  https://www.youtube.com/watch?v=5nWi-Pe46as
