I have several TV's to scrap out, besides obvious stuff is there any stuff I may not realize I should keep that has goodies inside? I have mostly only scrapped large loads of steel and such and really haven't messed with small items or a lot of non-ferrous stuff...
Thanks for any input..... I'm not in a hurry on these TV's, I buy and scrap junk cars and stay pretty busy with that and plowing snow and many other things in life so the TV's may still be waiting for me in a week or two.
What can you get out of TV's?

LOL! That one belongs in the "Where do you work" thread. In the living room, of course...Quote:

That's where I tore mine apart. When our TV went out last month, we bought a big-screen and I looked online to see how to scrap the old one. The one this guy has is the same as mine so I used Youtube as a guide as I went along. It was so heavy I really couldn't lift it to move it, so tore it apart on the living room floor. Then I had the glass tube left which is heavy, so I brought the tractor with forks to the front door, slid the tube to the door and out onto the forks so I could take it to my wood lot/scrap yard.Quote:

Something to think about also is if they work try pawning them. I did that with a few and got more than i would of if i scraped it.
Thanks for the replies. Watched that video and stripped them today since we're having an ice storm I had to find somethin to do to get out of the house so I escaped to the garage....
Cool, I went to the garage also, truck stayed in driveway...lol
Did you by any chance get any weights on like the copper you got out of each? I see TV's all the time but never bothered to stop and pick them up.Quote:

No, but I had just taken off my non ferrous so my containers were empty. I could weigh each material and give you the weight for all 3 of them which will give you a better average per unit probably. One of the TV's was very old and it had metal brackets all over, lots of screws and a lot more insulated wiring than the newer TV's. The newer TV's have more integrated mounting for circuit boards and such, plastic slots that the boards slide into instead of metal brackets to mount them, and less wiring between and boards and such. Much more integrated. If you watch in the video he pulls a big copper wire with heavy insulation on it, these are used to secure the picture tube to the housing, the oldest TV didn't have that, instead it had large sheet metal brackets to hold the tube in, which I left intact. The two other TV's had the big copper cable to secure the screen.
Hmm I don't have a good small scale, only a bathroom scale. I might have a digital fish scale which I could use to weigh my buckets, then dump them to get the Tare to subtract from the full weight... Those would likely be a lot more accurate. I'll look in a bit and get back with ya.
Thanks I do like numbers. It is fun to do the math and see what is worth doing and what is not.
I like to weigh a motor before I start, and then after I remove all the copper. The math is a great way to keep me motivated!
I take it there is a large transformer in there. They are one of my favorite sources of copper.
I have yet to watch the video. I am using free WiFi from neighbors, they need some connection help! LOL
It is slow but if it's free it's for me!
I posted this question in my newbie announcement, but this looks like a good thread to ask it again. I'm looking for a rectangular piece of milky white glass an inch or two long that my friend told me is in older TVs. Used for an insulator I think. Any info would be great, thanks.
I busted one open a while ago before I knew there was lead and phosphor in the tubes. I NEVER bust the tubes now. Anyway, I think its aluminum. I tossed it in the alum bin and the guys at the yard didn't say anything.Quote:

Ah. ok, thanks for correcting that.
Yea, those things your looking for (why,I don't know) are porcelain insulators. And that's what they do, insulate and draw heat away from the transistor.Quote:

I'd start looking hard at the board.
Theres a few parts where you can see copper, get them, most have a ceramic iron inside & around them & its easy to just save them up, pick out 1 & smash the ceramic & plastic & pick out the copper.
Some are made so you can insert a screwdriver thru the plastic bobbin & just pull the wire right off. I do 3 at a time. All CRT's have at least 1, sometimes 3.
The big chunky black plastic thing with red highvoltage wires coming out of it, its classed as 'shred' iron. We don't get that class here, so I chuck it in the rubbish. Speakers are iron.
Transistors, grab the copper heatsink on the bigger ones, twist it off the board & with any luck all the noncopper parts break off & stay on the board.
Look hard at the small 'Can' shaped transistors, some I have found have gold plating inside & around the base, same as its wires, gold plated.
On the older TVs, the remote control 'eye' has gold plating around it.
A B&W TV channel controller I found last week has a 'star' shaped contact disc inside it, its got gold plated ends on it, one electron tube on the controller (theres two) also had gold plated pins...
I have only noticed this week that a lot of the CRT TV's have a small coin sized metal can component on the board (looks like a fat short older can transistor), I took the top off & found gold inside...
Its to the left of the top of the black vertical IC chip in this pic http://image.ec21.com/image/zzscelec...CRT_TV_SKD.jpg
The quartz ocissilator, its a small flatish metal can with a number like 365.00123 printed on its side has a quartz sheet with what I think is Silver on both sides of it, they also sometimes have gold plating inside the cab, on its base & maybe gold plated wires on it. http://t2.gstatic.com/images?q=tbn:A...upIurvRRNTjQpw
Inside it, http://t0.gstatic.com/images?q=tbn:A...C7w6cUq1ZagoEl
http://t3.gstatic.com/images?q=tbn:A...dvl2Mx_-Nm5rTA
Theres silver in the switch contacts, or silver/copper. Try the main switch & any electric relays, theres copper in the relay too.
To get the relays, first I check its not a capactor, they look the same, but the relay has as many as 5 solder contacts under the board while the Cap has mostly 2.
I break the case off, peel the contacts away from each other & use a pair of sidecutters to snip directly from the side, 1/2 way thru the silver contact, this should cut thru the copper or brass arm & cut into the contact, this will splay it out a bit, expanding the cut thru the contact arm, the contact will come loose, or hold it with the end of the side cutters & pull it out.
I weighed my relay contacts today, I have 50grams of silver & 80grams of silver/copper base & about 20grams of magnetic contacts (has iron)
Lotsa plastic coated wire....
Transformers, only the older ones have them.
Ali heatsinks, the sheet metal ones holding the bigger transistors. You need to remove the steel legs on them too.
The extruded ones, you need to seperate the fins around the pin to loosen its grip, then pull it out. 66 of these equals 1Kg Ali.
In this pic http://image.ec21.com/image/zzscelec...ther_Board.jpg you can see at bottom right, the copper wire on the transormer, thats the one you can side onto a screwdriver & unreavel it by hand after smashing off the ferrite (ceramic iron)
To its right is a black box that controls the degaussing curcuit, not worth anything.
Above that is the ferrite transformer with a copper band around it.
Yea, I noticed he's asking the same question everywhere,,,? And if it's what I think it is, there's no real value in them.Quote:

Thanks for the info.
Maybe I should set up a repository for these pieces from y'all. I've got a glass blower friend that is very interested!
What do you think? It'd use up some of your trash, and help me out at the same time.
We get paid transformer price for those; that's what they are.Quote:

We don't ever recommend breaking the picture tube if you can help it, when you break it your creating a hazardous waste mess.Quote:

Wait, what? I'm confused now. Is it easier to get rid of CRT's if they're not broken? And how dangerous is it to muck around in there without breaking it?Quote:

As it is right now, and I see this changing in the future, places like Best Buy, Goodwill reconnect centers and Staples(for monitors) will take them in any condition within reason....... they wont take 100 busted to hell crts. Unless you can process crts w/o breaking the glass...... leave them alone. Watch a few youtube videos on how to discharge them, "release" the vacuum, and take off the goodies w/o breaking the glass before you "dig in". If you arent willing to do it the right way you will lose all respect from the recycling community and set yourself up for failure, not to mention huge fines if caught.Quote:

Also you might stir up the phosphor powder inside and I wouldn't inhale that either.Quote:

Oh, OK, my confusion stemmed from the fact that I thought the glass was being broken when the vacuum was released. I was mistaken.
So, the crt is still intact when the end is knocked off and vacuum is released?
Where is that disposed of then?
If you knock off the end, and break the cone part of the glass, you are still creating hazardous waste. The copper yolk can be taken off w/o breaking the whole end off. Personally, a little bit of stainless is not worth potentially getting caught by the EPA. You must do your own research for disposal.
Because it appears to me a hazardous thing to exchange my soul for my shadow.

nono, just trying to learn the right way to do this.
Where the red wire "plugs" into the side of the tube, unplug the wire, down inside the hole there is a rubber seal and you can puncture the rubber seal with a screwdriver to "break the seal" if you need to. That way there is no danger of implosion.Quote:

awesome, thank you.
I don't think I've broke one since taking that class at SMU a while back.
