Have several TV's- what to look for besides basics? - Page 2

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

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.

If your talking about the ring clips around the neck and the long ribbon you can pull out the of bulb if you break it. Its stainless steel.

We get paid transformer price for those; that's what they are.

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

Yes. Crt's are considered a hazardous waste. If broken, to get rid of them by following EPA Guidelines, you must place them into a container that seals so that no fines(almost unseeable pieces of glass) and phosphorus can escape, label the container according to regulations, then find a hazardous waste company that deals with them broken and pay them an arm and a leg to get rid of them. 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.

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

When you create a hazardous waste mess then the EPA gets involved.

EPA = $$$

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.

So, the crt is still intact when the end is knocked off and vacuum is released?
Where is that disposed of then?

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.
Hoss has done a few thousand that way.
