I know it ain't the backlight, and I seriously doubt it's the power board's electronics. Based on everything I've read about this so far, the best explanation was the edges of the screen somehow become porous or 'leak', allowing in water and/or oxygen which degrade the crystal. One reaason I suppose to take seriously the admonition to not spritz an LCD screen with a spray of glass cleaner. If it helps any, you're correct in that most TFT screens are normally white (clear) and darken only when energy is applied. I wonder if resealing the edges would help at all? I'd imagine completely 'dehumidifing' it first though would be a good idea, perhaps in a vacuum chamber or something. No, I don't have a vacuum chamber, I'm just thinking here! :-) I think the only way to settle this for good is to locate an LCD expert(s) and ask them. A little Googling ought to turn up some of the big names in the world of LCD research and expertise.
