That's a relief.

Well, I'm hoping that my overkill sloshing of ethanol is the main
culprit here, and that most of it will evaporate eventually. I've taken
the trim off the screen which will help, I guess - there are some small
vents around the edge of the actual screen panel. I'm reluctant to take
it apart further without good reason because I have zero experience with
LCDs!

It doesn't look human-dismantle-able, I couldn't see any more screws
than those that hold it to the plastic case.

Are they very delicate? I don't have access to a clean room but we have
any amount of rubber gloves, sterile dooberys and anti-static wossnames
in our lab at work.
The real problem is if the films are held together by decent adhesive I
might break something just taking it apart. This will be a worst-case
last-ditch option I think!
Thanks for the info
