Do you gig with your S900..??? Does it get moved around much? You're kinda at the mercy of the tech on this one. Hell that bulb could have simply been a ticking time bomb waiting to blow... You may have not even cracked the thing.., and the bulb may have simply blown and you're getting the run-around on a warranty repair backout.
If your board just sits in one place..., you'd have to bang it up pretty hard to crack that LCD bulb. Hell.., many guys here perform with theirs all the time and haven't blown an LCD bulb. I'd fight em on this one man!
