It's not the electricity that does you in, it's the slashing of your arms on the chassis as you rip them out in a hurry, then fall backwards off your chair, tangle your foot in the cord, and bring the still live set down on top of you... I've only seen the full chain of events, but I've definitely gashed myself yanking my hands out. It's worse if you had to use both hands to manipulate something in the set, you get a shock going in one arm, across the chest, and through the other. Isolation transformers don't help you in the slightest when there's a full circuit for a current path. It doesn't have to go to ground through you. I couldn't get someone studying television servicing to understand that, they'll have learnt the hard way, one day. -- [tim@bigblack ~]$ uname -ipr 2.6.22.9-91.fc7 i686 i386 Using FC 4, 5, 6 & 7, plus CentOS 5.
