Anything I should know before dismantling a large CRT telly?

[Mr Pounder]

Smash it to bits using A Hammer or A Blunt Instrument and slowly but surely dispose of it in your dustbin. Easy ...

Bad idea. The phosphor coating on the tube face is highly toxic.

Just take the set to the tip where it will be sent for disposal by contractors with the proper equipment.

TV sets haven't used big (mains) transformers since around 1950 (at the latest). Anything later simply won't have one (certainly not a 28" Sony).

Personally, I would not dismantle the set. Just get a load of mates around (one with a small van), and promise them large quantities of beer in return for using their muscle to move the set. Easier still, pay that £15, and leave it to the council.

[ARWadsworth]

Drag it into the street and then phone the council up saying "someones dumped a TV on the pavement"

More than partial - CRTs have a very high vacuum.

[Mike Harrison]

PSU caps won't be an issue after a few minutes, anode voltage may be. It won't kill you but could easily make you drop it... Get a long thin-bladed screwdriver, connect the blade to chassis or the ground wire that contacts the outside coating of the tube, then slide the blade under the rubber anode cap til it hits the connection at the centre. Even after 2 weeks there is a fair chance you'll hear a spark.

Wuss. I've shifted our old 32" Panasonic heaps of times and have the hernias to prove it!

My LA doesn't charge - even for things like scrap cars, up to an annual limit.

I once managed to (just) heave an ancient bloddy heavy photocopier into the front garden for disposal. The LA (after a lot of head-scratching) brought round a Hiab truck to collect it. They simply bashed a hole in the plastic case with what looked like a welder's hammer and inserted the hook of the crane. I was amazed that the plastic took the weight of the item.

Completely off-topic but =A31.30/l. Luxury. Currently paying =A31.459/l for bog standard unleaded.

Diesel's about 137/l here in Teflon.

Lots of nonsense so far. There will not be any charge remaining anywhere but the vacuum can be dangerous if the tube implodes. The safe way to vent the tube is to squeeze the nipple (that you'll find inside the centre spigot of the base connector) with a pair of pliers. Cover the CRT with a blanket whilst you're doing it and wear safety goggles. There will be a short hiss, once this ends there is no risk and the CRT can be broken and/or removed from the cabinet. You probably ought not to breath the phosphor "dust" from the inner surface of the front face.

It also has a habit of recovering after you've discharged it. I presume because the coating is such a large area the whole thing doesn't discharge at once. Whatever - even if you give it a dead short for a moment or two the damned thing can still give you a nasty nip twenty minutes later.

When I still understood such things I think the recovery effect was caused by displacement current (one of Maxwell's ideas) - but it's a long time ago.

I found a 28 inch Sony more difficult to get up and down stairs than a far heavier portable air con unit. Awkward shape but not as impossible as a 52 inch flat screen which I cannot move on my own.

[Skipweasel]

I beg to differ - I've been bitten by a CRT that's been off for a fortnight. They're supposed to have a bleed resistor - but they sometimes fail.

[Dave Plowman (News)]

The tube is about 90% of the weight so no point in dismantling. The set whole will be easier to lift than a bare tube.

[Dave Plowman (News)]

Not round here, they don't.

[ARWadsworth]

That's how I got rid of my old TV.

The best bit is when you smash the screen with the hammer.

[Dave Plowman (News)]

That won't be easy with a large screen set.

But if you must, break the neck off first. This is the least dangerous way of filling the vacuum.
