I found that when photographing CRTs, the use of a lens with a long focal 
length helps considerably.  I use a 100mm lens, at a distance of 6 ft (this
will depend on the size of the CRT).  Using this configuration does not
produce any distortion inherent with 50mm or less lenses.  I try for a shutter
speed of 1/15 or less; the brightness should be turned down so that in a
completely darkened room, black looks black.  As far as film goes, ISO64 
Kodachrome (or equivalent slide film) reproduced colors faithfully.  (The
importance of a completely darkened room cannot be stressed.  Reflections
not seen by the eye become readily apparent on film!)
