and didn't see it while searching. So the other day I drive over to my friend's house, SID working well. I get there, wipe the SID screen off with a napkin and when I went and turned the car on later the driver's side half of the SID is not back-lit. ALL of the pixels work fine and are readable, but at night (actually, during the day too) I can see that the passenger side of the screen is very well back-lit and the pixels are very legible. Is this just a matter of a bulb (probably $15 right?) having gone bad? I'm curious, how are the bulbs are configured within the unit? Two for making the pixels appear and two for brightly illuminating the whole screen?
