Anyone here have any experience with fixing monitor power supplies?

I have a Gateway Vivitron 21-inch (not under warranty, bought it refurbed a couple years back) that blew a capacitor in the power supply the other day. I'm interested in fixing the monitor rather than throwing it out since it's not your typical $89 17-inch throw-away. I paid $600 for it and feel a wee bit of effort may be able to ressurect it.

I'm no electronics pro, so I'd like to chat with anyone who may have had some experience in this area.

Can we assume you already tried to replace the cap and that didn't work?

That's part of the problem. None of the components are marked. If I found someone who might do this for a living, they may know where to find a reference for the parts.

OR- maybe I should try to find a new power supply for the thing? Might be cheap, I just have no idea.

The PSUs in monitors are very similiar to TVs. If you know a good TV repair shop they should be able to repair it for you.
Usually, the smaller establishments with experienced engineers are used to working without model specific manuals. They will likely be able to replace the unmarked cap using their experience to determine a (likely) suitable value.

Edit: Since it's a $600 monitor and since you are here asking these questions I think you should not risk making matters worse by attempting to simply replace the cap yourself. From the sound of things the cap wouldn't have failed so catastrophically in isolation and there are probably other faulty components in the set.
Leave be and get a professional involved, it sounds too nice a monitor to experiment on

The capacitor blowing may be cause by a manufacturing defecting in the capacitor or some other problem elsewhere in the monitor. Just blindly replacing the capacitor may cause further parts to blow.

As you don't know much about electronics it is your best bet to get somebody else to have a look. The voltages in a monitor are extremely high and can be dangerous if you're not careful.

Sorry, not quite what you want to hear but it's not safe to play about with the internals on a monitor if you don't know what you're doing!

Yeah, I hate opening up these small dummy terminals I work on when I have to do adjustments on the screens. I'm always afraid I'm going to get shocked even though I know what I can touch and what to stay away from. I don't do any major work on them replacing anything though. Large monitors would even be worse and I won't touch them myself.
