Any safety precautions to be taken when decasing LCDs?

[riposte_18]

I've seen a lot of topics about decasing CRTs, and discharing, and ensuring that the neccessary protection is taken, since the capacitors of CRTs retain strong electrical currents, but I haven't seen much about LCDs?

I know most people won't bother decasing LCDs, because, well, they're slim enough and small enough that decasing isn't worth the extra space you'll achieve.

I've had to decase my LCD though, because its a former commercial LCD, used in my brother's company in an interactive kiosk, that sat in those noodle box places. As a result of sitting next to the kitchen area, grease has formed this really gross, smelly sticky layer all over the plastic casing, and after an hour of trying to scrub it up, and ignore the smell, I found I could decase it, and there'd be minimal work to be done in cleaning it! (Hey, its a free LCD, I'd rather clean it than spend money on a new one)

After cracking it open, I found the LCD is pretty self contained, with just a PCB board for the monitor controls, and some stuff on the back for the power input/monitor plus/sound in. My main concern is with the electronic stuff hanging out the back. In particular, I can't remember my university electronics, but there's like I think a metal circular magnet, with copper wiring around it on the back. See, from my memory, I thought that was something to do with like, magnetic flux, but I'm worried if I accidently touch it, or any of the other stuff out there, even when the LCD's off, I'll get zapped. There's a couple of other things there too. I'd take a pic, but I'm at work right now. I think since the rest is fairly self contained in a metal box, that should be safe to handle, although I am worried about a build up or anything on the metal casing? I'm very cautious around electricity, I stuck a knife into a powerpoint when I was a kid, and turned out alright (I think?), but I'd rather not take my chances.

I've read RandyT's defender cab walkthrough on how he broke down his LCD, but I didn't really see much in the way of safety tips or precautions, which actually would have been a better read if I saw it *before* I decased my LCD, but oh well.

Although I do have one last quick question. I noticed the plastic casing gave lots of breathing space to the internal LCD metal box, presumably for heating purposes. If I encase it in a wooden frame around the top/bottom/sides, with a PVC covering on top, and a couple of wooden struts on the back to keep it in place (and maybe a cover to keep accidental fingers from touching the back electronics), is that sufficient ventilation? pretty much the only way for it to disperse heat will be through the back, since the front and sides/top/bottom will be totally enclosed?

Just don't decase it! You need room between the screen and the bezel anyway (newton rings), and you can keep your waranty. As for old free ones: go ahead, but this technology went so fast, you probably accept either horrible viewing angles, horrible black levels or horrible lag and ghosting levels, or even worse, all together . Even today's sub 100$ TN crap is probably better.
