 and welcome to Retro Tech. Today, I want to do a product demonstration on conversion strips. This is a normal conversion strip that came straight out of this television. It's a just magnet on a piece of plastic with some nice two-sided tape. This is the original one, but let's say you don't have enough in your TV and you still got some color convergence, you can either try to take these old elements out and move them around and maybe you'll get a result or sometimes the magnets can go bad on them and it might be time to replace them. I got this set off of eBay and they appear to be pretty high quality made but probably homemade. It's just a piece of plastic with a magnet and some tape and it's a two-sided tape on the other side so you can get it set and stick it on the back of your CRT tube and this one came again on eBay was a set of 10 and let's just see how it works. You see up here we've got some pretty bad color convergence where our colors are separated and I want to try to clear that up with the conversion strips. The conversion strips are going to be great at clearing those colors in this corner. You got to know that when you're working with convergence though it can take more than just these strips and we'll go through that some more. I've got a small round magnet that if you move it actually on this one along around the yoke it'll help with the wonkiness on the corners because there's not really any kind of menu to adjust a lot of the things that you can adjust in higher-end monitors on the CRT just standard television. So to get this corner cleared up again we're going to try to move in these conversion strips these new ones. We'll see how they work to get this corner cleared and then I'll show you some other tricks and tips on working with convergence. Let's look at the safety equipment first before we get back into the monitor because this is a test that you're not going to be able to do with a discharge monitor. You have to have your monitor running so you can see the results on the screen as you move it around. Unfortunately you have to use a lot of these magnets to get all your geometry fixed on the corners and things like that and around the edges on these older televisions. What I've got here is a high voltage marigold industrial glove. What I do is I wear this glove and then I actually put a second layer over top of that glove to give me double protection. This is a high quality leather glove on the outside and now you've got dual protection for when you're working back behind the CRT while it's turning on. Again just take your time when you're doing this make sure you've got the right personal protective equipment don't try to save money on gloves. It's about your only thing that you can use to protect yourself. Mine cost about $80. Taking a look back here at the back of this CRT you could see these convergence strips and there's some already in here. I've already tried to use some of the newer ones a little bit just to play around and there are the older ones. Those will affect your corner convergence. So the corner for instance if you want to fix your corner up here you're going to play with these strips or add strips in this area. So today we're looking at this corner because it's the worst so we're going to be moving around these strips and maybe even add in another strip in there to make sure that that corner convergence is set. Some other things that are going to help convergence on this particular monitor and other ones are these convergence rings. Now these again can be tricky. There is no just straight convergence adjuster on this television so you actually have to use these rings. Okay I've zoomed in in my corner here you can see just the different how the white red are separated the blues and reds are separated and as again I said I'm going to put this in with the tape side going to the monitor or to the back of the CRT tube and I'll just move it around back there so these things just kind of line up and look nice and even again. Whoa so as you can see here I move this around it makes a big difference right there it's not even that big of a difficult move. I got it set in there I want to look at basically the top three cubes that are in white and then the top one in red and I want to try to get them all to line up. So I hope you can see there how that's cleared it up as far as the convergence is concerned. We still have a geometry issue in that corner and that will be fixed with more magnets not convergence strips but little round magnets. Let me give you a quick example though on what I'm going to do with this little magnet. Okay this is quick screen change up but I want you to see on my middle finger I've got a piece of two-sided 3M tape and then on the middle of it is just a small tiny magnet. Now this one was on the back of the CRT it just wasn't in the right position. Let me show you how this will actually affect the corner could not just convergence but the actual geometry on this particular television. Now on the back of the tube I want you to take a note and see do you see this this I'm now I'm not touching it okay do you see this this is where the magnet was it was actually on the yoke assembly and I noticed that it was just it just moved a little bit and as I wiggled it around it actually got better so I'm going to put my gloves back on before I get too close to it but I'm going to re-seat this along this yoke just the gray part on here and I'm going to move it around on the front and you'll be able to see the the convergence as well as the geometry change. I've got my gloves back on and now I'm going to just go back here and I'm going to move around this magnet so you can see basically what's going on so right now I've got it in its original position you see how that moves that whole thing and again this is not on the back of the tube this is actually along the yoke so I will just sit there and I'm going to try to get this is nice and square up there in the corner as I can and I'm going to set it down but you can see how on these older televisions you have to use magnets because they don't have any kind of a menu or even potentiometers to adjust certain things at all I hope you can see how it's kind of gotten it cleared up let's go look at the back real quick back here around the back and you can see how I've reset that magnet it's pretty close to the original spot but it did have to be moved a little bit I'm going to do more calibration adjustments and show that in a future video on this tv but for today we're just going to concentrate on those convergent strips and using that small magnet to fix one corner at a time so let's recap a little bit to fix the wonkiness in the colors you can sit here for a long time and work on it which I will work some more on it but you're going to want to use some kind of corner convergence strip we saw how we put those in but those just go in behind the yoke and are worked around back there and then I also showed you how to use the small magnets sometimes this can be set on the back of the crt on this one it had to be set on the yoke that's how you get a lot of the quarter convergence fixed something to realize this is a 20 year old tube television so you're probably not going to get it perfect but you can get it back to almost perfect and definitely better than it was definitely better was when I got it and so if you happen to have a tv that needs more convergent strips or you think your convergent strips really aren't working anymore they could have the magnet could have gone and lost a little bit of magnetism over the years maybe or just not as effective you can either switch them with these or try to reset the ones you've got but it's a small investment and I think it's kind of worth it to change it out for some new ones instead of always reusing the old ones but you can definitely reuse these old ones and try to see if they'll help both are good option so if you have any questions about the convergent strips I do have some other videos about convergence on pvms available please refer to those or leave me a question in the comments and I'll be glad to answer them thanks again for watching Retro Ted
