Zones is a good place for a new one, (that's where I would go), but if you're looking for a used one, try Boeing Surplus in Kent, they usually have a good supply of 17" to 21" used monitors for $35.

If you know enough about electronics not to kill yourself, you could take the monitor apart. DON'T try it if you don't know enough, because you can KILL YOURSELF... no kidding... high voltage and big capacitors hurt, & can stop your heart.

Usually the problem you describe is a problem with the power supply board, look on the back side of the circuit board (the side without the components on it) if you're lucky, you'll see a discolored, maybe burned area. If you're really lucky, you'll find a solder joint in or around that area that isn't completely smooth, but has a small circular or semi-circular crack in it, and looks like a nipple. You have to look close, with a good light. If you see this, resolder that joint, and your problem will most likely be fixed.

BE CAREFUL!!!
