there is place where for 1-2 dollars more they sell a universal cap kit. They give you enough of the right kind to fix any model completely once (including power caps. But that's really not necessary.)
Still trying to dig it up. It was a great deal.
Also there is a site that points out which are the caps that power the screen.
What's good about that is if you did have a GG with a washed out screen you could find out 6 caps in whether or not is salvageable before using up all the other caps.
I'll dig up these links in the next few days and post them here.
Mostly so I don't forget about them again myself.
