I'll have to pick up some of that stuff for this and other things. I've heard it mentioned more than once.

I didn't think to snap any pictures of the insides, mostly because it was so straight-forward. Remove the five screws on the back of the case (two are under the bottom rubber strip), use a small screwdriver to carefully pry the clips in the seam between the front and rear case halves, then deal with lifting the board out of the front case. You might need to work it off some heat stakes, but it's not as bad as doing a Pioneer or a 48. Just be careful of the flex cable holding the LCD to the board, since it's all one piece.
