TL;DR

Retro Ralph safely replaces failed CRT in Road Blasters and diagnoses the root cause.

Summary

Retro Ralph documents the failure of a CRT monitor in his Road Blasters arcade machine during a livestream and demonstrates the proper procedure for safely diagnosing and replacing it. He shows how to discharge a CRT using a high-voltage probe, swap in a working monitor, and identifies the failed components in the original monitor (blown flyback transformer, cracked component, damaged ceramic capacitor). The damaged monitor will be repaired and reused in his Street Fighter 2 machine.

Retro Ralph@ 0:15 — Marks the moment of the monitor failure during live broadcast

Retro Ralph@ 1:16 — Explains the safety rationale for using a high-voltage probe over traditional methods
“You don't want to touch the anode and you also want to make sure your other hand isn't touching anything metal because you're gonna electrocute yourself if it is.”
Retro Ralph@ 2:33 — Critical safety instruction for CRT work
“When this fuse blows, this filter cap is loaded with voltage. So when this all blows out, one would think it's safe to just pick this up. Yeah, well, if your hands hit the bottom of these connections, you're going to get zapped to hell, which I did, by the way.”
Retro Ralph@ 5:06 — Demonstrates learned lesson from personal electrocution and warns viewers
“I'd be super bummed if I couldn't play it. But we do need to fix that G07 chassis because that's gonna go into the Street Fighter that's right here on the side of me.”

Okay, so in a recent livestream, I had a CRT die on me in the middle of the stream. Pay attention to the CRT behind my left shoulder. Bedroom.

So that's... Do you know what I'm saying? What was that? That sounded weird. Oh, no way! Oh no, my road blasters just totally died while we're on the stream! No!

All right, let's get this started. The first thing we got to do is remove this speaker grill. It takes two screws. We're going to remove that because we got to gain access to this piece of glass that covers the monitor. So you just lift it up and pull out from the bottom. And then we're going to remove the paper monitor bezel. And then that gives us access to the monitor. So we're going to unscrew these four screws. And then before I pull it out, I'm going to discharge it to be safe and disconnect the connections on the back. Okay, we're in the garage and I'm going to show you how to discharge a CRT. So this is the tool I would typically use and I would typically wear oven mitts. Yeah, oven mitts. You don't need these. They don't do anything. It was just some weird protection mechanism. You can make fun of me in the comment section all you want, but those oven mitts made me feel better. The reason why I'm not going to show you with the screwdriver method is because you could mess up when you build this. It's totally a method to use, but it's a little scary. you hear the snap of the voltage, and honestly, there's no real way to determine whether or not the voltage is actually all gone, so you have to kind of keep on doing it. So we're going to scrap this, okay? And the reason why is because I want to be able to, and we're not going to use the gloves. I don't need the gloves anymore. I'm not scared anymore. I'm not afraid anymore. Hey, so tell me in the comments what movie that's from. Okay, so we're going to use this high voltage probe The reason why it makes the job way less scary you can see the voltage drain and I I gonna show you that right now and I not going to wear any gloves okay so the machine is running right now so step one is to shut off the machine so I gonna I gonna reach back here and shut it off the other thing is you want to unplug it so make sure you unplug it I'm gonna unplug it right now so now there's literally no power to this arcade at all so we're gonna go around back and this is really easy I was shocked it's very simple so you take the little alligator clip you're gonna stick it on the frame of the monitor okay so when they say stick it on the chassis that's where you're gonna stick it and then what you're gonna do is you're gonna put this probe under that anode you don't want to touch the anode and you also want to make sure your other hand isn't touching anything metal because you're gonna electrocute yourself if it is so take this one hand just to be super safe and put it in your back pocket, okay? That way you're not going to be tempted to touch any metal. And then all you're going to do is you're going to want to bring the camera in real quick. We're going to take the probe. We're going to put it under the anode. Now pay attention to the voltage meter. You're going to see it drain. Instead of a snap, you're going to kind of hear it maybe if you can tell. I'm going to try to move in.

So you can hear it and you can see it. It's going down, down, down. It's almost at zero. Now, what I like to do, even though it's not necessarily necessary with this tool, is remove it from the anode, then put it back in one more time. No voltage. And that's it. We can safely remove the alligator clip, and we just discharged the CRT. I'll have a link in the description of this tool. I know it's expensive, but the thing is, if I'm going to tell you how to do something safely, and you're going to work on these on a regular basis, you should probably own one. Let's go back inside. all right with the crt safely discharged we're ready to continue this project we're gonna make sure everything's disconnected from the back and then we're gonna pull out the crt from the front be careful they're heavy and i'm gonna put a known good one in now keep in mind i didn't actually fix the app the problem i had with the original one we gonna i gonna show you what was wrong with it because we are gonna fix that because that crt is gonna end up in my Street Fighter 2 because it a much nicer CRT than in my Street Fighter 2 When I reconnect everything back here make sure power is connected make sure ground is connected make sure the RGB signal from the actual PCB is connected And I'm going to slide the ribbon cable for the adjustments up front so I can fire it up. There it is. It's working. So we're going to make sure we adjust the vertical size, the horizontal size to fill the screen. make sure everything looks good before we put the bezel and everything back on it's gonna be harder to do later so there it is we got the bezel i'm gonna clean it while it's here because if it's dirty underneath the glass it's gonna bug me and i'll disassemble everything all over again put the speaker grill on get the control panel connect that and guys we're gonna be ready to play some road blasters again oh yeah let's do it so you're probably wondering what happened to the original Road Blasters monitor? Well, this is the monitor chassis, and this is actually the component that got damaged. We've got the flyback. This blew out, and there's a crack right here that I'm going to show you. The hot right here also got damaged because this little ceramic capacitor blew out. When this all happened, this fuse also blew to protect the rest of the components. Now, here's the bad part. When this fuse blows, this filter cap is loaded with voltage. So when this all blows out, one would think it's safe to just pick this up. Yeah, well, if your hands hit the bottom of these connections, you're going to get zapped to hell, which I did, by the way. Lesson learned by this filter cap. So we've got to get these are the components we need. We need a fuse. We need the flyback. We need this ceramic capacitor and the hot. We can get all those components online. I'm going to get all those and we are going to fix this because this is going to end up back on that road blasters monitor, which will end up in my Street Fighter 2. Let me show you the crack really quick so you can see what I'm talking about. It pretty gnarly Watch I zoom in and I focus in on it and you can see there it is There the crack right there So it had so much dust and dirt on it I didn see it initially and then if you want I show you that capacitor that also blew you can see that right I'll see it right there okay so we got to replace that we got to replace the fuse and and the hot and then after that we're good to go so I'm gonna have a whole video on this we're gonna do this to get this back up and running but I just wanted to show you what this was. In order to troubleshoot this, there's a great flow chart out there. This is a Geo 7 monitor chassis. I'll have a link to the flow chart and I'll show it to you on the screen really quick. It will help you quickly diagnose problems with your Geo 7 monitor chassis. All right, let's go play some Road Blasters.
