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.
