mostly you want to be careful of the "big red wire" and careful of everything when it's plugged in and turned on. pieces of metal may actually have a high voltage on them rather than being grounded, on older tv sets even the metal chassis was often connected directly to one side of the power line! please be extremely careful. note that you'll want to use a mirror so you can be behind the monitor and see the screen rather than awkwardly and dangerously reaching around while being in front of the monitor. usually the focus(es) (sometimes there are 2) adjustments are on the high voltage multiplier (the thing the big red wire comes out of, the other end being connected to the picture tube, and possibly another somewhat thick "focus" wire connected to the picture tube socket). these do usually take a little time to settle as you adjust them so go slow. also make sure to degauss the monitor thoroughly first, sometimes this will solve the problem. definitely use an insulated screw driver (and one that's clean, crud can conduct high voltage rather nicely) and keep your hand on the plastic part (wood is not an adequate insulator for high voltage, especially since it does tend to absorb moisture etc. over time!). BE CAREFUL! DON'T DO IT WHILE YOU ARE TIRED OR IN A HURRY! i've worked on a lot of monitors, and i'm still very, very careful and only do it when i'm well rested and have plenty of time, and no kids or pets etc. around creating distractions and other hazards.
