LA's only the HP150 use a casing with holes in it where the 16500 LA uses
dark IR passing plastic .
On the couple of occasions when I have looked at an HP 16500 where the
power up diagnostics said the touch screen was 'impaired' it was due
to one of the plastic IR guides working its way loose and out of
position. Putting the guide back in its proper position fixed the
problem.
