I did not notice any air bubbles on my display. Anyway, I only ruined
a small patch in the upper left corner of the display, otherwise it
works fine. I can live with that (until I get a btest-2), it's
probably better than me destroying the whole display trying to stick
on a new polarizer ;-)

The sturdy
layer I fear was the polarizer - that needs to stay on.
The ones that had the protective layer removed showed visible air
bubbles
making it obvious to the operators that it had to be removed. This
happened
perhaps 5% of the time.
Apologies - if anyone has destroyed their panel this way - please
contact me
and I will try to find another solution - perhaps sending you a new
polarizer that you can peel and stick (carefully to avoid air
bubbles).

Every single unit has the protective film still on the polarizer,

were not removed by Quanta (we can get this next time!). You can
take off
your protective film, carefully, it's only 4 screws - all on the
bottom of
the brick (the brick is the LCD - motherboard assembly), you have
rotate
the brick to the left, unscrew the two screws that you can get to
(philips
head), and then rotate to the right and get the other two screws.
Next take off the left and right short green things (part of the
"bumper),
and then take off the plastic face plate over the LCD. Now you
can peel
the thin protective layer of plastic off the polarizer.

I tried to do that yesterday. After disassembling the unit, I tried
to peel off the film starting at the display's upper left corner.
However, what came off was a rather sturdy layer of plastic sheet. I
had expected some thin film like you would get on any new mp3
player's display. But this layer was like a part of the display
itself. Fortunately, I only took off like 5 mm, and because it didn't
feel right, I tucked it back in.
So ... what should the protective film look like? Did anybody else
try this? Is it a notable difference in appearance, or should I
rather leave it alone?
