It's been days. Go all out.Well, after much banging and slamming, I got it open. It appears undamaged (at least as undamaged as it already was). I saw enough warning labels to make me take a step back. Everything from "x-ray shielding may be needed when operating at high-voltage" to "high voltage, don't touch that!". Next, I'll take a deep and thorough look at safety precautions for re- capping it. (ie, discharging everything without electrocuting myself before I start poking around)
The highest voltage is on what looks like a suction cup on the side of the picture tube. Shorting that to ground will get rid of the worst,take a needle, solder a good piece of wire to it, tape the needle to a dry stick, with the other end of the wire going to the chassis of the monitor. Slip the needle under the "suction cup" (it really isn't it's just a rubber disk that well covers the actual high voltage contacts that insert into a well in the picture tube). If you're lucky, there should be a spark (I say lucky since it proves that you've properly made contact
with the contacts underneath, but if there's no spark, it could meanthe voltage has already dissipated, or that you didn't make proper contact).
That discharge of the high voltage on the picture tube will ensure that you won't get a shock merely by rubbing against the picture tube.
The remaining higher voltages are more likely contained, certainly the most exposed voltages would be on the bottom of the circuit board.
I can't remember why you wanted to open the monitor, so the potential
dangers depend on whether you actually need to do something to the
circuit board.

Thanks everybody.
