   Howdy.  I recently posted a question asking about my dead 1084, and would
like to thank the people who replied.  Just in case there are any others out
there who are suffering in quietude, here's what I was told:

There is a fix to your problem.  If your monitor is the same as mine (and it
sounds exactly the same) the problem lies in the flyback transformer not being
properly soldered to the board.  You need to take the board out of the back
of the monitor (after disconnecting most of the cables) far enough that you
can get it out to do a little work.  You then need to unsolder the tabs that
hold the metal shield onto the bottom of the board, and take off the shield.
If you inspect the solder joints around the flyback transformer (it's the
biggest single part on the circuit board.  The one that the high voltage lead
to the side of the picture tube comes from.), you should find that the joints
have cracks in the solder.  These cracks cause intermittent sparking sounds,
and as they get worse intermittent periods of monitor failure.  You need to
find them all and resolder them.  Then put everything back together.  Before
doing this, I recommend you turn turn the monitor off for a considerable length
of time to let all the capacitors drain.  Even so, there may be the danger of
getting a shock or something, for which I take no liability....  If you do any
of this it is at your own risk....  etc...


I'm not easily able to post this myself due to access restrictions I am working
out.  Be sure to send any questions to:
