I had a similiar problem with my 1084, it would go for a while and
then shutdown. The power light would still be lit but there would be
no picture on the screen. Occasionally a small amount of percussive
maintenance would persuade it to fire up again for a while.

The cause of this problem in my case was that the solder joints
connecting the flyback transformer to the pcb had failed. To fix it
all that was required was to open up the monitor and resolder them.
Give that a try, you might be surprised...
