Scope screen for sale! I had an old osiliscope and I had taken out the screen. the last time before I had taken it apart the screen worked. I have started working on another project and now I have run out of funds for it, so now I am figureing this screen I wanted to play with, might just get me enough funds to finish my project. I need at least $30 for the screen, thats with shipping! I feel a little sad to have to part with it.... but I really want to finish my new project.

I'm thinking of cutting the phosphorecent screen off of a CRT and seeing what effects I can produce by shining some high intensity UV light on it. Removing the screan is going to be tricky since the entire CRT is a vacuum on the inside. I know I'm going to have to be really careful and let the pressure in slowly or it could implode and send shards everywhere, but I'm also worried about what dangerous substances might be in the CRT that I could expose myself to. Does anyone know if there is a danger of lead/mercury/etc on the inside of the CRT, and what safety precaussions I can take?

I am planning on buying some classic consoles soon, (NES,SNES,SEGA Genesis,N64, etc) and I want to be able to play them on the kind of screen they were made for, a CRT. I have one that a friend gave me, but due to being moved a lot, and probably not gently, the picture has fallen out of alignment. Specifically it cuts off a large portion of the screen on the left, (leaving a thick space of black on the right) and is at a slight angle. It is not all that big of a shift, but it is a real pain in games with items in that section, because ammo counts, health bars, treasure chests, and even chunks of text can be hidden in that space. Could anyone tell me how to fix this issue? And how hard it is to do?

Would like to separate the two pieces of glass that make up screen. Does anyone know how to do this? Can you remove epoxy that is holding them together.
I broke apart my Tv set and literally smashed the screen with an axe. Why? Because there was nothing good on. But anywho.....I heard there is lead and other bad stuff in the glass so i am a little worried that i breathed some of that in. Also, i love the look of the glass and would love to use it in some art projects. Is it safe to work with? Thank u.

I had an idea to saw the glass tube projecting off the back of a CRT picture tube (the part that has the pins on the back and surrounds the electron guns) that I have lying around and put it in a plexiglass case or something cause it would look cool. I need to know if there are any dangers in doing this that remain after the obvious things such as discharging the tube and breaking the seal on the back of the neck. I do know that the screen is coated with a phosphor that is not good for you but this should not be an issue because i am not going to be working with the actual screen part right?

I've got a 19 inch flat screen crt monitor hooked up to my mac. And when I play my music really loud, the image almost shakes like it would if I had the stereo hooked up to the power bar with it like it used to be. The stereo is on it's own breaker right now, but is it doing that from the actual vibration of the picture tube or is it dieing on me?

Hello! I'm getting a bit tired of playing with disposable cameras... there's only so much you can do with them. Well, I acquired a CRT, presumably from an oscilloscope, a couple of weeks ago and I want to get the flyback out of it (and figure out how to use it) so I can make a Jacob's ladder or Tesla coil. Does anyone have any ideas on how to proceed? Here are some pictures.

I have huge 21 inch crt monitor which i found yesterday in the trash i plugged it in now. it works but the image has some distortions the color that should be black is bright gray and all other colors are like addition to it. the image looks very bright and with bright gray tint. setting brightness and contrast to minimum does not help much there are some kinda scratch lines across the display. the lines form a shape of a 'lightning' with horizontal lines and diagonal that connect them. the density of lines is higher when i switch to higher resolution the image size is severely affected by the brightness of what is displayed. it grows larger about 1 cm on each side when i open a window with white background other than that the monitor works ok in all resolutions from the bios screen and up to 1600x1200 what can be the problem ?

I was tearing apart an old VHS camera and decided to rip the LCD out of the viewfinder. Much to my suprise I find a CRT monitor not a LCD! This screen is about 1/2 inch. It has a 5 pin connector that leads to the motherboard and a chip on the bottom that says A118121. Obviously two of the conections would be V+ and ground, but what about the other three? I would like to turn this into a composite or VGA compatible screen (maybe even a crazy tiny oscilloscope) but I need some help. Any suggestions or leads would be greatly appreciated.

I have a TV that is in a place where the remote will not work (Dont ask its complicated lol) and I want to rewire the ON/OFF switch on it so that it will be like a foot or two away from the tv. Do I have to discharge the CRT on it before I work on the ON/OFF switch which is only attached by wires to the CRT and flyback transformer circuit. Could I just wear some thick rubber gloves to work on this because Ive never discharged a CRT before and have no interest in doing so.

I've got two CRTs for parts, as well as a 20" LCD tv, whose screen is toast. What can I do with them/their parts? I've thought of a guitar amp project with the lcd (speakers/amp of the tv) but that seems like a waste, if there's more great stuff that I can use them for. I know CRTs have tons of stuff to salvage...just not sure how to rip it all out (both CRTs have been unplugged for >month, so their capacitors should be safe, right?) There are a million ibles I want to work on, so I thought I'd see what I could do with what I've got....I don't have enough lights or fans...just these monitors and tv for now. So, what would you do if you were me? Ok, thanks!?

Question by ferraririder123 7 years ago | last reply 7 years ago
Is it worth it to take the electron gun out of a CRT when salvaging parts? I've seen people remove the electron gun when they take apart the CRT but I don't know what they'd use it for. What can you do with a CRT electron gun? What chemicals does the gun contain? (I know the screen has toxic phosphor and stuff but I'm talking about the gun itself). Also, is it safe to vent a CRT tube? I have found that you should vent the CRT tube before working on it, by smashing the end from a distance, so that it won't implode if you happen to break it when working on it. But is it safe to puncture open the tube? There are toxic phosphors inside and I worry that venting it could cause toxic chemicals to go airborne.

Question by Ethanal 8 years ago | last reply 8 years ago
What I want to do is remove the phosphor screen of a CRT and see what happens if I hit it with intense UV light. I know I've got to look out for high voltage, and that if I don't let pressure into the vacuum very slowly with a small hole the glass will shatter and spray shrapnel everywhere. I'm also concerned about mercury/lead and any dangerous chemicals I'll be exposing myself to. Can someone explain the dangers and what I can do to avoid them?
Question by kramerr 9 years ago
Hi all, I have taken apart an old color crt monitor which was not working and I don't know how I could reuse the crt from it, I have a feeling it still works and that the problem was the flyback transformer, and would NOT like to throw away the crt. I would like to know if anyone knows how to drive a crt, without having to do something TOO complicated, I will be happy with very minimal results such as just a blue color being displayed, or such, as long as something gets to appear on the screen. Then I can use the x and y axis controls (the little plastic carrier on the neck of the crt) to control the image sizes. I heard that you have to find out which pins of the crt are for the filament and provide around 6V to it, but how do you find this out? Also if someone knows how I can test the flyback to make sure that is the problem, it would be helpful. Any help is appreciated. Thanks in advance, P.S. Attached is a picture of the crt.

Question by ReCreate 10 years ago | last reply 7 years ago
Hi. I recently took apart an old CRT and removed the flyback to experiment with the high voltage output. Unfortunately, the core cracked when I was working with it. A sizable chunk even came off, but I reattached it by carefully fitting it in the slot and gluing it in place. Now the output voltage is much less spectacular from which I have seen other people do with the same transformer! It works, but I think the damaged core is where the problem is coming form. Does anyone know how to repair it better then what I managed to do? Thanks!

I saw this hack on the MAKE blog yesterday, and it reminded me of a project I wanted to try a few years ago: a computer monitor like the one in the movie Brazil (pictured below). This device appears to be a small CRT screen behind a large Fresnel lens. The lens is easy enough to find in the form of a reading-magnifier, but it was the screen that puzzled me. I couldn't figure out what I could use that I could hook up to a computer. I thought about hacking digital picture frames, but they wouldn't have the cool curved look of an exposed CRT. When the post on MAKE came out, I thought that maybe the screen he used from a Coleman Lantern/TV (which are pretty easy to find on eBay) would work, but I'm not sure. So my questions are these: 1.Could I use this as a computer monitor using similar methods as in the blog post or a different way? 2.Would it be a problem that the TV is black and white? 3.If it's possible, is it likely that an electronics amateur like me could do it? I have experience in circuit bending and blinking LEDs with Arduinos, but little else. This is the deciding factor for me if it is truly possible, I don't want to take on something well out of my skill range. I realize that even if I did succeed, it wouldn't be very useful, but I'm still interested. Is it possible? Thanks, Noah

I've been reading up on Jacob ladders and tesla coils for a while now, and decided to try to make a Jacob ladder (the tesla coil just looks scary and advanced) I've taken a part an old CRT. And I was wondering if you could tell me if it looks usable. I'm wondering slightly if I broke it when I removed it from the 'plate' it was stuck in. Pictures will show what I mean. Sorry about the bad focus on the pictures. Taken with a phone, and it was slightly too dark for it to be able to take good pictures. The brown cables looks like it's just fast in the flyback transformer, but I did not remove it. I tried to get a good picture of the text that was on in case it means anything to anyone. Also, what I can gather by looking at this is that the red cable is the high voltage cable, and the low(er) voltage cable is either the grey, or white one. - Is that correct? Thank you very much for your attention, and thanks for any replies. And this site is amazing. I'm just amazed at how creative people are. Oh, and please let me know if I posted this in the wrong category Zaek.
