OK.  I think we've got two different problems here.  The Vertical Hold
problem is simple.  All you have to do is open up the monitor and find
which of the little blue dials is the vertical hold.  I had to do it
once a very long time ago so I can't remember which one it is.  But to
get the Rainbow monitor cover off, there is this little plastic cap on
the back of monitor.  Pop the cap and voila, there is a screw.  (Took
me the damnedest time to find that little sucker).  Anyways, that's the
only thing holding the cover on the monitor.  Oh yeah, make sure the
little peg foot that comes out the bottom is ALL the way in.  That sort
of impedes the cover removal.

The second one of blanking screen I'm at a loss for.  Sounds like it 
might time to retire the monitor and get a new one.  (Cheaper than DEC
Field Service).
