When you select one of the four dark climate buttons, does the orange indicator light up to indicate your selection? The orange lamp that lights up when you press one of the buttons is a board mount LED I believe, but the greenish back light that lights up the words should be a traditional board mounted bulb. Both the LED and the incandescant bulbs are soldered directly to the circuit board. But if the orange indicator is also not lighting up when you press the button, you probably do have a more serious problem like a crack in the board itself. In terms of the junkyard, you may have better luck price-wise on ebay, I've seen these things up on ebay for around 20 bucks.
