Depends on how the board is attached/held in to the housing. Some boards are easy to remove, others are damn near impossible, seriously.
Here's what I'd do: If there are obvious screws to remove, remove them. If the board does not lift out easily, then see if you can figure out what's holding it in place. If you can't easily figure it out, or if you try to get it undone with no luck, then that's when a smart non-technician will give up and hand it over to a pro.
