 This is not an illusion. This is the actual dust and dirt Built up in the back of this CRT. Watch this It's almost as if It was smoked in Look at that All right, folks. This is not an illusion This is the actual dust and dirt Built up in the back of this CRT. Watch this This dust Is because of the fans. I'm convinced that the excessive amount of dust of this is because of these intake fans Which are a great thing to cool the monitor down as it's running because there's three of them inside But if they're intake fans and there's dust in the area and it's not cleaned It sucks the dust in through the main intake fan and then just Soots it in here and builds up over years. I gotta Get the air compressor ready Get the brush kits ready and I need to get a lot of this dust out of here Wow, so that was a good two hours of cleaning just to get the soot all off all this stuff I had to get my professional commercial grade air compressor and Blow for a long time used all kinds of cleaning brush kits that are ESD brushes This is one of the best CRT designs for Internally that I've seen in all my experience working on them just to give you a little bit of information on why I say that real quickly first off this is a secondary deflection board that we've recapped that's over here on the right side and What the way this Monitor is normally set up is this over here where the flyback is is going to be a really high heat area Normally, you've got a lot of ICs same thing with this heat sink plate a lot of heat sinks over here Well, this gigantic fan runs at 2,000 Revolutions per minute or something and it's always got to be running or the CRT will not power on it sits right here and sucks in cool air from the outside and just Constantly blows in that area forcing cool air up and then what that does is that sends the hot air on here up and Naturally out the vents and then there's another fan that sits up back here to help cool And then another fan that sits over here on top of this other power supply to help cool. So that cooling Actually helps this whole monitor Maintain a lot of the integrity of the parts Of course as I said before it also causes an immense amount of dust to possibly build up if you don't clean it Now these capacitors are amazing guys I went through here and looked at the capacitors on the chassis and they are just a beautiful high quality Most of them are Nisha Khan Rubicon and then KMH just some beautiful capacitors in here and other than the deflection board and Some of the neckboard capacitors. I wouldn't even We're not even going to go in here and replace a lot of these because they are so good There's so much life left on them Let's go now. I'm gonna put the rest the boards back in here And we'll go look at it one more time when it's reassembled and get some tests going here We are put all back together got plugged up as video again stereo audio And then just the power AC cord plugged in but everything else is put back together And I did do a little bit more research. These fans are actually gonna be blowing out They're not intake fans like or they're not they weren't set up to be Intake they were set up to be exhaust So I was incorrect when I said that earlier just in case I want to go back over that Those fans should be blowing out and then this would blow out and that one will blow out of the power supply But let me take you around and show you everything before we finally turn it on after all our servicing This is definitely a moment Where things could be a little bit nerve wrecking but it's My goodness a thousand times cleaner and quite beautiful compared to what it was Okay, let's just take a look here at this IO board Audio and video Really cleaned up nicely Now one of the important upgrades we've been working on is trying to get Some new fans installed in here We've got again our three fans and they're still pretty loud even after cleaning them and What I've got here is a premium Not to a fan that we're gonna be installing now the the interesting thing is is There's an alarm system on this board and if the fans are not working or don't meet a specific requirement Which is two thousand RPMs Then the monitor will just turn it completely off. The problem is it still will trip the alarm if you just Sit there and directly input The cable into the header Even though it meets the specification. I was not able to get it to work without doing this little trick So here's our connection going into the monitor and you'll notice the yellow alarm cable coming from the fan has been severed and Then over here. We've got a splice. The black is the ground cable What we've actually done is spliced our alarm cable coming from the monitor To ground and all that's going to do is trip that alarm to let it know when currents going that it's actually Being activated and then it will let the fan just run Like it should So we're gonna have to do this alteration For the other two fans to install them once we get these fans installed. It should be a lot quieter Then obviously when we started let's get our splice here covered Now we're ready to mount this on the power supply and then we'll have to get the other two fans ready I'm finished installing all the Noctua fans So first we've got 80 millimeter And that 80 millimeter over there And then we've got the 92 millimeter down here I've got it turned on so if it stays on for five seconds, then that means the fan alarms Are not kicking in and that we're good to go Wow, that's a lot wider That's gonna do it for today's episode Please make sure you check back with the channel in a couple weeks for the final installment on the NEC XM 2960 we'll be going through calibrations the finished product and how the fans ultimately work after some serious testing and If you do need any more details on the fan modification, I do have a specific video for that linked in the description There's also a linked playlist for all the prior videos on the NEC XM 2960 and the restoration process to this point so please go back and refresh if you're missing any information or want to check out anything else and One last special. Thank you to everybody for subscribing and all the patreon members Who've been kind enough like Tom to send in their wonderful CRTs here to be serviced so we can all learn more about them and Document them online. Thanks again everybody. I will see you all next time with some more retro content
