I work in an electric motor plant and the reason some of the wire is colored is to help the people assembling the product know which wire goes where. The color just tells them what winding they have.

Very nicely laid out. This is the kind of info that anyone wandering the internet search engines hopes to find, thanks for sharing......
;?)

I figured it was easier to post the pic's than answer the same questions 10 times. Hope I'm right,,,

Oh, I have another question - those big metal bands that go around the larges part of the glass - do you remove those? I'm ascared to for fear it might make the whole thing explode!

the pictures are worth more than a thousand words to a old fart like me. Im so glad i found this group, im reading and viewing posts some 2 years old--and still learning tons of great stuff. Thanks all of u who post pictures along with your comments.

yeah yeah.....that was good , but where are the nekkid ladies??
Anyone guess that the full moon amps me up a little?
;?)

Dang, I always wondered what those big heavy black things were int he third piture top right corner - I didnt know those were transformers and couldn't find ANY info on the google search for those either was probably doing it wrong. thanks for the info!

The technical name of those is a "Flyback Transformer"... You can find info on wikipedia

The only way I know of to get these apart is with a sledgehammer, which is very messy and I don't recommend.

When you look at a circuit board, the hi voltage orange/red wire comes from those black transformers and goes to the picture tube(suction cup). Like I said earlier I think their epoxy wrapped or baked but there is copper wrapped inside, and that is what make some of the hi voltage for the tube. I've never tried to beat one apart, we just turn them in with other xformers. Looking at the third picture you can see where I cut the red wire off the xformer after discharging.

Someone on here took one apart and for the time invested in getting it apart it just wasn't worth it.

Still the question though, what to do with the CRT when your done with it.

Just snip it somewhere to break the "circle" and look at the fresh cut ends... it will be either copper(redish) color or aluminum(silver) color.

You are exactly right RCA. That is the best way to know whether it's copper or alum. I can tell by weight alone.

My city just opened a new transfer station and includes tv's and monitors in its recycling program.

Whenever I have a load of brush from yard cleanups on my truck I weigh it down with the scrapped tv's I have and get rid of it free.

I take mine to the county transfer station. They will take 5 at a time for no charge. I strip them and put the case back on over the CRT.

Nice post, I am just harvesting my first monitor and had some questions, you answered them all. By the way, I just took a razor knife down the middle of the degaussing cable and peeled the tape right off, no real problem.

We have a company over in Ohio that accepts them for recycle (I think you pay). Out east there is a huge amount of factory's and I'll bet someone out there recycles the tubes also. Just need to really research it.
Some Goodwills will accept them whole and some stripped with the plastic put back on.

The only ones I don't like are the sticky tape ones. When your done with one of them everything around you sticks to you whether you want it to or not!

Ferrites can be sold as scrap as stated here. They are made of a combination of zinc and iron or magnesium and iron powders pressed together. I'm not sure they are a true ceramic. They are around the monitor chokes and also as donut or tube shapes around wiring in monitors and most compute equipment. Sometimes they are painted and often rubber sheathed. The ferrites around wires are selleable RF chokes to electronics hobbyists. They are sold as shreddable steel scrap in general. If a scrapyard questions you having them in your load simply tell them to check them with a magnet. Their rule is if it is magnetic it has to be scrap steel or iron.
Also shown in the photo of the power supply board are small copper transformers on the board which can be popped off. A couple in this photo are wrapped in yellow tape. They are can be sold to some scrapyards as low grade copper scrap. The current pricing is around 20 to 25 cents a pound, sometime higher but don't assume every scrapyard takes them. You need to ask first. I have about 15 scrapyards withing 60 miles of my house and only three of them take them. Regards, Chris Hyder.

watch this video, the last 3 min show how they process the tube itself

M88: I've been looking around for places to get rid fo the tubes but so far it's NG. I can get my hands on a bunch of monitors but if I have to pay to get rid of the tubes its not worth it. I am on the border of NJ and PA, PA seems to be less strickt with their CRT recycling, they do not count the tubes as hazardous waste as is done in NJ, so Im hoping to find someone out that way.

Some places you pay a little, other a lot to dispose of tubes.

thought I would re read this thread and brush up on yall's tips. I am lucky enough that the parish I live in said to toss them into same trash can as regular trash I just cant overload the can otherwise the mechanical arm that lifts the can will struggle. I do have a tip for peeps that are allowed to put in their trash can, oh as far as glass tubes in the can they said they separate it at a transfer station so as not to go to the dump.. my tip ill post somewhere or maby someone already has, when scrappin a tube to lightly crack the neck as you know to let air in otherwise when the dump truck empties your can you get an explosion or implosion rather lol.. I forgot to do that to a 36inch the other day and my wife heard it inside the house lol... anyhow that's yall for good advice I still have a question or to but im researching it maby ill get good answer from e waste buyer..
