 On unit labelled QUOZL 2, serial number PCL10EN6460012F, two bad pixels
 have developed in the past day.  Both are blue.  One is near centre, the
 other is near top line.  I've inspected them with reversed binoculars to
 verify no brightness nearby.  I've verified that they continue to show
 with backlight off, though as clear rather than as blue.

 Unit has experienced travel in a air-bubble padded bag in trunk (boot) of
 a car over about eight trips of one hour each, in relatively normal
 temperatures for the region at this time of year.  That is, between 23 and
 42 degrees celcius ambient outside the car.  It is a white car.  The unit
 was not left in the trunk while the car was stationary.

 The other two units QUOZL 1 and QUOZL 3 have no sign of bad pixels.
