The 1950 is made for Commodore by AOC (Tawianise) and only has
Commodore's name on it.  Commodore QC has nothing to do with making or
adjusting the 1950.  The monitors are sample inspected on an incoming
basis to verify that the monitors are up to our specifications.  It
would appear that several monitors (dead, etc.) got through our incoming
inspection process but ALL monitors SHOULD be tested by the manufacturer
(AOC in this case) and adjusted!!!!  We are talking to our supplier to
fix the quality problems.  The 1950s where on hold for several weeks due
to the vertical jitter and tube tilt problems, but as I understand it,
are now corrected and shipping with all the neccessary fixes.  I will
ask about what, if any policy, Commodore has regarding the units with
problems in the field.  You should note that your monitors are covered
under the one year warrenty period and if they need fixing your dealer
should handle it or an authorized repair center.  I will update you good
folks out there in net land when I find out more information.  It may
just be a matter of the repair centers getting the information on how to
fix the monitors!
