I have a Gateway 21" monitor about 10 years old.

It quit working. Were it a smaller monitor I would just toss it but being a
nice 21" I would like to get SOME idea what it might cost to have this
fixed.

The problem is that there is no image at all. Everything else seems to work
fine however. I hear the normal "hum......click" when the monitor is turned
on but no image appears. I hear the normal "voom....click" when I press the
de-gauss button. Connecting my laptop to it, it "sees" the monitor
connected. However, despite whatever I've tried (including different
cables) no image appears.

I'm just trying to get a ROUGH idea what it might cost to fix this, to see
if it's worth even seriously considering fixing.

often if a power supply detects an short or other problem on one of the
outputs then it will shut down. This may be why the relay clicks. there
could be a shorted vertical or horizontal problem.
In a monitor this old,and judging by the symptoms you mention, the
line output transformer may well be bad (recently I have seen several
monitors of this vintage with bad LOPTXs) but before fearing the worst,
try testing what the other posters have mentioned, resoldering etc.
Also check the HOT for shorts, and with it removed connect a 100w
bulb across c-e and plug in, see if you have B+.

replacing the other parts, such as transistors etc. will not cost more
than pence really if you do it yourself. Only the LOPTX is dearer,
typical prices round here are between 20-60€ for a new one. I
wouldn't bother with this if I was workign on a 10 yr old monitor
personally.
