I decided to go full blast, 2 hours @ 350 F. I removed everything from the screen except for the actual liquid crystal panel itself and the attached control circuitry which cannot be removed. I shielded the control circuitry from the heat using a triple layer of tin foil (operating on the same theory as tin foil masking for a heat gun).

Holy crap! 350F is *WAY* too hot! When you bake out parts that have been exposed to moisture prior to reflow soldering, it's normally a few hours at just over 100C, or around 212F. Any hotter than that and you'll be wrecking things. Not to mention plastic outgasses all kinds of nasty substances when you get it that hot.
