Followup: Active matrix pixels dying

["John H. Kim" <jokim@mit.edu>]

I posted here describing how two pixels on my TP701C's active matrix
display had (mostly) turned blue.  I got a few replies, two of which
said the pixels were most likely in the process of becoming stuck.

One of these messages said that when his display was doing this,
sometimes he could make it disappear by pressing on the screen
nearby.  I tried this, and found that if I pushed towards the
left, both pixels would turn blue (whereas before it was one or
the other).  Conversely, pushing the screen towards the right
made them both disappear.  As you can guess, I tried pushing
harder, enough to maybe reseat the TFT within the case.  It seems
to have worked - I have not seen either pixel get stuck in the
last two weeks.  I have no idea why this works, or what's going
on...
