    Im gutting an old crt for a possible mod or if it doesnt work out, for the sake of gutting it.

    anything I should worry about? after opening up the case theres all these warnings about somin somin tube x-ray doo-dad....stuff? Is there anything I should worry about before completely gutting it?

    There are no x-rays in CRTs.

    There are tens of thousands of volts and enough residual current to easily kill you, but no x-rays ;)

    I strongly suggest you leave them alone unless you know what you're doing, search around the forum for "flyback transformer" and you'll find a few posts on the matter.

    Basically the capacitors inside can hold a charge for a long time, so even if it's unplugged it can do a lot of damage.

    You could but that'd take the best part of the fun out of taking a CRT to bits... look for a big round thing, and there should be two prongs on the other side of the board... lick these for the tastiest surprise!!!! Because of the way electricity works it stimulates your tastebuds and it makes your tongue think you're actually eating chicken...

    best fun you'll have in your life!

    now lorguis what if somebody tried that than what BAM no toung left.
    there are x-rays in crt's. and those caps and the crt its self(it acts as a big cap) can easily kill you EVEN IF IT IS OFF!!!!!!!!

    if you are even asking these types of questions Stwongbad, seriously dont go anywhere near the CRT.

    Let me simplify this a bit...

    If you don't know exactly what you're doing, and how to do it safely, it could easily kill you. Numerous parts within a CRT can hold a charge powerful enough to kill you for upwards of a year, I believe, and certainly for over a month.

    I've done it very carefully before, but honestly wouldn't do it again. Unless you have a very good reason to do so, it's something best avoided.

    *speaks with lisp* Oa grweat nowsp you tell meh! :duh:



    Certainly glad I asked you guys about this as I decided to at the last second. But now im a little worried about all those 19" CRTs I see at the edge of the road as they may suddenly explode just to spite me.

    I actually service CRTs as part of my business, and I can tell you a few things.

    If you're not aware of the risk, leave it be.

    If you don't have a discharge rod, leave it be.

    If you don't know electrical hazard safety, leave it be.

    And if you don't have someone there on standby during assembly/disassembly to make sure you survive, leave it be.

    You may think I'm being overdramatic, but a chance mishap cost me pieces off the side of two fingers. It's no laughing matter when you blow a piece off yourself or complete a circuit and the capacitance dumps into you and stops your heart and fries you black. I ask for extra every time I service a CRT, to cover the cost of having someone there to call the hospital if my discharge rod somehow doesn't fully empty the caps.

    Yes, I'm overly cautious, but ask around, we've all stated they can be deadly.

    If you are going to lick "the big round thing with two prongs" at least video it.
    or just dont do anything.
    I recomend the second option

    firstly, it's spelled Lorquis,... with a Q, (not to mean to be an arse, but 10 white russians.. kinda turns me into such),

    But to be honest, anyone who has to ask the risks of gutting a crt, without finding out the risks of doing such a thing, in my opinion deserves to be subject to natural selection, after all one day they will wonder "what'll happen if i fly a kite into a pillon and put my cat on the other end"

    if you're stupid enough to mess with dangerous thing such as mains elec' and caps storing oodles of current, then frankly my opinion is, you do not deserve to be around to mess with such devices. That kinda person is likely to down an entire block's power just because of something stupid...

    I don't mean to be a dick, but if you're going to do something abolutely stupid then do it, but don't involve anyone else in it (yes, i know i involved myself but that was to illustrate how fantasticly stupid messing with stuff you don't know about is!!!)

    ((PS, this has no influence on the thread about generators in this same group, which is indeed serious, and is trying to save the life of someone!)

    Hey I wasnt going to do anything stupid! The reason i posted this thread is so i DONT do anything stupid if anything im less likely to use one let alone open one for risk that i might drop it and blow up my house.

    Lorquis are you suggesting that I should do what you suggested with my tongue/crt just to find out what happens?

    There's a neat little trick you can do with caps to give your mates a giggle:

    solder a length of unsheathed cable to both terminals and charge the cap,now hang it on the door handle inside the IT department and call for assistance!

    You'll be the centre of attention (once the victim has recovered and stopped beating you to a bloody pulp) :D

    No, he's saying that if you're enough of an idiot to actually lick something that's storing lethal amounts of voltage, at least be courteous enough to have nobody around that'll try to pull your frying body from the caps and get shocked themselves.

    hobbs - yes, I believe so, but you also need to know how to use it. It's not as simple as just poking any metal part with a grounded rod. The thing you need to get at is under a large suction cup, and it wouldn't be especially difficult to slip when getting at it and hitting an unfriendly bit.
