I suppose it is completely off.  I tried looking at it on an angle to
see it the screen was activated but not backlit but I soo nothing but
a black screen.

Yes.

There is power and the power switch works.  When the data cable is
FIRST plugged in there is a complete normal screen with all data where
it belongs...if it would stay on, it would be perfect.  BUT when the
data plug is plugged in the screen is only on for 2 seconds and
exhibits a 1/2 cps flutter (that is to say it flickers 4 times) then
blanks.

This is repeatable in just 5 seconds or less, what ever time it takes
to unplug and replug the data cable.  It is my theory that as the
screen "comes up"  it puts a strain on the power supply...or perhaps
on the filter capacitor output that drains what ever charge has built
up and then it flickers out because the power supply cannot supply the
needed current to keep the voltage up.
