Dismantling a Monitor

**Mechanic688** · 07-14-2011, 07:29 PM

I took a few pic's that I hope will answer a few questions for the newbee's on dismantling a monitor. Hope this helps someone; Just make sure it has not been plugged in for awhile, don't want anyone getting shocked! And please do not break the tube.

Cover unscrewed and ready to remove.

Just removed the cover, ready to unplug silver box on top. Silver box has a small circuit board inside. (can usually cut open the box to remove the low grade board) Box is tin.

Removed the plug-in box on neck of tube(see socket pins)

Circuit board unplugged and removed from the monitor, black transformer top right, surrounded by alum heat sink. Two smaller alum. heat sinks in the middle. (only things of value on this low grade board) If IC chip is big enough then I will use a chisel and pop it off, (lower left). Just a couple of copper bearing items (coils-chokes) on this board to be removed.

Close up of the yoke and degaussing cable around the tube. Small silver braid wire is actually copper braid, and degaussing cable is larger black cable that goes around the tube. Yoke still attached. (degaussing cable is usually copper or alum. wire wrapped in black tape)

The yoke is next after removing metal clamps; some have one clamp, others two. (the clamps are usually stainless steel)

Sliding the yoke off the neck of the tube. I usually take the yoke after removal, and set it on some concrete and hit it with a hammer(use eye protection) and the ferrite the copper is wrapped around will break or shatter.
Throw the ferrite in the steel bucket. Copper goes as #2 clean.(the reason for it being #2 is because it's varnished)

This is a bonus; Inside of a computer power supply after removing cover. Fan to the right while up top is transformer, straight in is two alum. heatsinks.

Excuse my ignorance, but what is the tape wrapped device in the back of the power supply. I find them in everything, they appear to be layers of copper wrapped in layers of tape.

A fan?! I dont know how many TV's/CRT's i've torn apart that dont have a fan. In fact, none that i've torn apart have ever had a fan. Pretty cool! That degaussing cable is copper, to anyone who didnt know. Just unwind the black tape and BAM, their ya go. I believe that sometimes it can be aluminum also...you can usually tell by the weight.

Also, the big black transformer surrounded by the alum heatsink, is their anything in that? I've never torn that apart. Always all the other copper windings, and smaller transformers.

Good pic tutorial!

I don't think you'd be able to tell by the weight as much as you could tell by the color. 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.

Interesting, I've always thrown the ferrite in the trash. It's mostly ceramic right? Seems to me to be about the same a sticking a brick in with every load as it's not really recycleable is it?

Sometimes, if you score the black masking tape and cut, then grab one or two strands, you can pull it through the whole length of the cable eliminating the need for unwrapping.

I USED to use that method , quite a bit.
Until I cut them into about two-foot sections, fold them in half , put them into a toaster oven (I picked up the toaster oven scrapping, plan to use it for tempering steel knives, My other profession/ full-time hobby scrapping affords me)...

Put them in the toaster oven on 400F or so , even on broil, they get sticky, and then put a board (like 2x6) under and they are sooo much easier to slice and peel.

Course the aluminum cheapo TV ones would have been better tossed in with "55 copper" power cords.
Which I unintentionally had been doing for a while and getting 1.10/lb. .

Newbie question here.

Which wire is the one you have to discharge? I've heard stories of people getting some nasty shocks from live wires inside monitors.

Cheers!
Tom

Start here, it should pretty well explain it all. This is why we keep telling you folks to read the older threads. Hope it's not too confusing. If so, ask away. Hoss, take a bow,,,,lol

that was a computer power supply the fan is in,,,

The black transformer has copper in it but I think it's epoxy baked so we turn them in with other small transformers and small motors. The black tape on the degaussing cable is real easy to slice thru with a razor knife, I can do 5 of them an hour while watching tv.

**TheHoss** · 07-14-2011, 10:38 PM

Hey, yeah, sorry i didnt see that, try being nicer about correcting folks.

Hoss, wasn't being mean, I just enlarged it in case anyone else mistook the last picture, sorry. Your right, I've never seen a fan in a tv or monitor. I took the last pic the same time as the other dismantling so I just thought I'd add it also, for the newbee's, like I said.

**Mechanic688** · 07-15-2011, 11:12 AM

It sticks to a magnet and is also the material that magnets for your car stereo is made out of, I've always heard that ferrite is recyclable. No I'm not padding my weight bucket.

it has a powdered metal of some sort in it.

Thanks to Wiki for this;

A ferrite is a type of ceramic compound composed of iron oxide (Fe2O3) combined chemically with one or more additional metallic elements.[1] They are ferromagnetic, meaning they can be magnetized or attracted to a magnet, and are electrically nonconductive

**cpayne** · 09-12-2013, 09:35 PM

ferrite is powdered iron that has been fused together under pressure, it acts as a core to increase the magnetism from the coils ,like the core in a transformer. it goes in with the mixed metal around here. some places may pay more for it. think of it being made like a sintered bronze pilot bushing for a manual transmission back in the day.

Here is an idea of the copper that just came out of a normal degaussing cable. About a pound worth.

Get 100 of this, and have close to $400

I use a wire cutter and it is easy as pie

**Mechanic688** · 07-16-2011, 09:57 PM

And here is an example of some aluminum wire that came out of some degaussing cables, you can tell by weight after you've done quite a few. Doesn't seem to be any rhyme or reason for the colors.

But where are the nekkid ladies????
