This caution needs to be added to.  Some wires still have those 10,000+
volts EVEN AFTER THE POWER IS TURNED OFF and this very high voltage can
persist for DAYS due to charged capacitors.  These voltages can ARC through
1/4 inch or more of AIR.  If it discharges through your body, it will
likely kill you.

There are ways to discharge the capacitors but I couldn't (and wouldn't try
to) say how exactly.

So, if you *still* want to open your monitor, be very cautious and STAY
AWAY from the wires, especially the fat, well-insulated-looking ones.

	Be careful in there,
