[Sderby] Monitor

[Simon Hales]

Hi

Just a quick safety warning I haven't seen anyone mention yet.  Turning
off a monitor does NOT make it safe to open!  The capacitors in a monitor
are so big, and charged to such a high voltage that they are capable of
storing a lethal charge for some hours after being switched off and
unplugged if you're unlucky.

I have previously come across safety advice that claims a monitor should
be left standing for 24 hours after disconnection before any attempt is
made to open it.  Presumably if you open it, fiddle with it and plug it
back in, and it still doesn't work this means you have to wait another 24
hrs before having another go!  Probably time to start looking for 2nd hand
monitors, decent 15" monitors seem to be quite cheap now, presumably
because offices etc are all starting to buy either 17", or even
flat-screen replacements.

Regards

Simon Hales
