It seems the monitor in question is being temperamental, I managed to get a picture out of it in the end, but only after about 3 reboots and some wiggling of wires. I have to say it is a Macintosh (14") Colour Display I got practically free off our local dump so I'm not complaining too much ;o)
I guess we all skipped right past the "Are you sure your monitor is working okay?" part. :-)
If that is the 14" Color display which was not a trinitron, and also was not the "Basic Apple Color Display" then it may have a blown internal fuse. Apple's mid-range 14" display (I'd pull a model number but I'm too lazy to climb behind my partner's desk) from the mid-90's was infamous for blowing it's internal fuse.
The fuse is relatively easy to get to and the capacity is pretty clearly marked, IIRC (it's been many years since I fixed this one). It is soldered down, however. In the case of the one that I have here, after removing the fuse, I soldered in a fuse holder (little plastic dingy in two parts that screw/snaps together to hold the fuse inside) so that if the fuse blew again replacement would be easy.
I also found that the difference between a fast-blow and a slow-blow fuse was critical. The thing blows fast-blow fuses but a slow-blow fuse survives. Apparently, the root cause of the problem may be in the degaussing circuit.
Anyway, if that's the same model 14" monitor, it may have this fuse problem. If it's working intermittently though, then probably not, as fuses don't come back to life. At least I've never seen a zombie fuse.
