Sure, I’ll do that whenever I get around to taking a closer look at the monitor, which should be in the next week or so.

So finding information about video wall processors has been a journey and a half. I started digging into them back in 2016 with a phone call to an AV place whose sticker was on the side of one of my monitors. He gave me some names of some companies that made them, and from there I found what I could. After a few dead ends with software that is nowhere to be found to configure old devices, and experts on certain devices having retired years ago and not wanting to be bothered there was a lot of trial and error and reading of manuals. But here we are finally. Haha. Mariokart 64 where everyone gets their own monitor. This is via composite, but I have some s-video breakout cables in the mail and I'll take some new pics once I have them installed. This device DOES accept/output RGBHV, but unfortunately will only display 240p/480i via composite or y/c. Through all of my research I haven't found a device that accepts those resolutions via RGBS. I have some videos of fractals and other things running on this with my old setup (a Vector video wall processor) if anyone is interested.

That is insane Mariokart setup

On another note I wouldn't mind having an XM-29 Plus/XP-29 Plus. I've got a PVM-20L5 for trade, so if someone is interested hit me up.

Haha. I promise you'd be disappointed. I blew the engine years ago and have been working on it little by little, but it's nothing to look at.

That videowall setup is pretty cool. I remember they used to have something like this at Best Buy in the 90s, it was usually playing Super Mario 64. I always thought that was really cool. Stuff like that was partly what made me want to get a monitor like this in the first place. My N64 is RGB-modded; playing Super Mario 64 or Mario Kart 64 in RGB on the XV29 is pretty awesome.

Here's a picture of the residue I was talking about. This is before I cleaned it. I had to break off some of the plastic to access it.

Image


Here's what it looked like after I cleaned it with some alcohol.

Image

The alcohol cleaned away the residue pretty well, and all of the solder connections look pretty good now. Unfortunately, doing this didn't solve the issue, because it still came back. It occurred to me that the other areas might need to be cleaned too, but I'm now thinking not - because I have a new idea about what causes the issue. I already observed before that physically moving the monitor will sometimes make the problem go away, but considering that other things seem to influence it too, I wasn't sure what to make of this. Now, I've observed that moving the monitor can not only eliminate the issue, it can also make it appear when it's working normally. Now that I know this, based on things I've read about CRTs, this is a very likely sign that something inside the monitor is loose. I read something that suggested that things like the board on the deflection yoke and the power supply are good places to look for something like this. So I'm going to do some more tests to try to at least locate the source of the problem. If I can find the source, then I need to find a way to fix whatever's wrong.

That just looks like solder flux residue to me. Definitely not the cause of your issue.

I did notice that after cleaning the residue, the image seemed noticeable brighter than usual. I’ve also noticed that fluctuations in brightness often happen before the problem appears. I just cleaned out a little piece of debris (I don’t know what it is) and now the image seems even brighter. I can’t say for sure if this is just a coincidence or not though; the brightness seems to vary a lot at seemingly random times. For now I’m going to do more testing to see if what I just did eliminated the issue.

Well, I've tried some more things and it had no effect on the issue. I think I'm about ready to give up on this monitor; I've already wasted so much time on it, it doesn't seem worth it to continue. I'm not sure that even a professional would be able to fix it. The problem also seems to have gotten worse, to the point that it makes the monitor basically unusable. I would buy another one, but I haven't been able to find any more for sale. Does anyone (in the US) have an XM/XV/XP29/29 Plus for sale? I'm only interested in the 29" models. Barring that, I think I'm just going to go back to the dual 20" RGB monitor setup I was using before. I'll have to rearrange my setup a little, but it seems to me like this is the only logical option left at this point. I'm tired of not being able to play all of my games; if I set up the former 2 monitors, then I'll be able to play all of my systems again.

A professional can fix it. There's more to repairing electronics than cleaning off boards :wink: And all of these monitors are pushing 25 years old and will develop problems eventually. Better to have yours fixed than buy another one. Cheaper probably too. Where are you located?

That’s great, but there’s no one anywhere near me who can do this. I live in the southeastern US.

Are you sure? If you're on facebook, you should join "The CRT Collective" and ask if anyone has experience with repair shops in your area. They still exist.

I'm pretty sure there's no one in the town I live currently who can repair the monitor. So I'd probably have to travel somewhere with it, which I really don't want to do. I'm thinking it wouldn't be a bad idea to have another monitor, even if I eventually get this one fixed. That way, I'd have a spare in case either of them have more problems later on. You have at least 4 of them, right?

Right now, I really just want a working monitor. I've done everything I can do with the monitor myself, and trying to get someone else to do it would be a huge pain in the ass. I want a monitor I can use now; I can worry about getting this one fixed later on.

I totally get that. I just can't imagine shopping for an XM these days with them costing $1000+. I got one of mine for free, and paid only $50 each for the others. For me, some travel time and money spent on repairs that would make the monitor last another 20 years would be worth looking into vs. buying another. :mrgreen:
