When you pull off the back, you'll notice a transformer with a red wire coming out that goes to the top of the CRT. You should resolder everything on that side of the board. Electronics (rosin core) solder and an cheap pencil soldering iron should do the job (all available at radio shack, maybe). Heat each solder joint with the soldering iron and then apply solder to the connection while still holding the iron in place. Once the solder has evenly flowed over the connection, remove both the iron and solder. Do not disturb the connection for a few seconds, as it needs to cool. The connection should be bright and shiny. If it's dull, you have a cold solder joint that will give trouble later. Also, use only enough solder to get the job done and don't bridge two connections with excess solder. If you've never soldered before, find some junk PC boards (such as from a stereo or PC monitor) and practice on those.

While you are at radio shack, pick up some desoldering braid. You'll need this to remove solder in the event that you need to extract a part or create a solder bridge.

Also, keep the tip of your soldering iron clean by running it across a wet sponge while the iron is hot.

IIRC, the G2 control is either on the CRT board or the flyback transformer. Use caution in these areas, as theres voltage there that will lknock you on your butt!
