<Do we really need line eaters?>

Hi,
   I am having some problems with my 1902A.  (It is a nice monitor,
but...)  after some use, the picture slowly fades away.  And a sharp
hit to the side, sometimes, fixes it.  And after I turn it off, and
wait for a while, the monitor starts working again.  Does anybody out
there had the same problems?  Any help would be appreciated...

Sounds like the filament of the picture tube is going out. The filament
voltage is supplied by the high voltage transformer. Check closely on
the bottom side of the printed circuit board, in the area of where the
transformer pins are solderd, for a loose solder connection. Some of
the 1902A monitors were made by NAP (Magnavox) and poor soldering was
a very common problem.
