The TV had the last laugh.

So, last week I took a TV from the warehouse next to me that the girl wanted to get rid of in the office. I let it sit for a couple days, and then on Sunday I dismantled it, discharging it as well. I'm worried about getting shocked by these things, so I'm careful with them (or so I think). Fast forward to today (Tuesday). I go to dig something out of my low grade board bin, and grab this board that is still on top. It gave me a good jolt, nothing huge, but more than what I have felt out of a regular socket. More than anything, it scared the crap out of me. Respect the TVs!

It's the capacitors, they can hold a charge for weeks or months sometimes,,,lol
a healthy respect for them doesn't hurt, kind of like a snake,,,:&

Careful there, Ive done 100's of tv's / monitors and never got a shock. Took a ceiling fan apart once that sat in the driveway for about two weeks and that sparked when i cut the wires out. weird

I had a computer power supply last week that still held some electricity. It was a seperate board from the main board, it had its own capactors, I think it was a extra 5v power supply running off the main 12volt supply.

It made a nice spark as something sorted out the cap. Slightly scarey, nothing else I have picked up sparked before....

Except car windows as I was cutting thru them with loppers to get to the dash. (in the dark..)
This is an example of triboluminesence, where light is emitted after energy from friction is introduced into the chemical bonds of the glass.

Thats why i always have a tub of water nearby. Just dunk them in there when i'm giving the cat a bath. It still shocks me but its funny to watch what happens to the cat.

(i'm completely joking of course, dont call PETA)

(besides, its really the fish tank i use)
