CRT VGA-Component Odd Ripple Effect

[SuperRAD]

Hello, I am using a MisterFPGA VGA to Component on my CRT.

Something I noticed is that the screen and games ripple slightly more than they would on my traditional consoles. If I plug my PS1 in via AV I get a much steadier picture. Is this a component issue or is it something I can fix in the ini? I attached a vid as an example but it's hard to see in it.

EDIT: To offer some more information, it's like horizontal lines slowly moving up the screen in sort of bursts. Additionally the i/o board is from Antonio Villena

Basically I have a steadier image on real hardware, but I can't tell if that's because of AV vs Component or my settings.

Thanks!

UPDATE: I believe this is a known issue with Antonio's board and component. I am going to buy the s-video adapter and use that as it seems to solve this problem.

Strange, I don't have that issue with my Antonio board and component. I do have a similar experience with the SNES core, but only that one, and that is an issue with my particular Panasonic CRT that is known to not like SNES timings.

Try different cores and see if you always have that issue. Where did you hear that this is a known issue with Antonio boards? Did you reach out to him directly and ask about it? He is usually very responsive.

Also, make sure you are not using the scaler in your INI file.

I was mistaken, the issue was with composite using Antonio's adapter found here:

Thanks. That is an old adapter that is not the newer MikeS version.

Sorry, but I'm a little confused and could use clarification. I just purchased the Composite/S-Video adapter from Antonio's site so I could use an S-Video cable to my CRT. Should I have purchased something else that is more up to date?

I also forgot to mention that this issue I am experienced of rippling / dot crawl, whatever it is happens on the OSD main menu screen as well as cores. Doesn't happen on a pure PS1 though. Not sure my ini is the issue but I can post it when I get back home. I'm hoping S-Video will fix this for me.

There are two different ones on his site. The Active one for 25 is the better one. However, it would be better to just make component work. Post your ini file. Have you hooked up other things to the component input that look fine, or other inputs on your TV? All the details matter. Thanks

Ah I thought the more expensive one was better because the description suggested it didn't rely on cores. Feel stupid now because that's the one (30,00 €) I ordered. Here's my .ini file attached. I use the alt as my main one for some changes, but both experience the same issue.

[thorr]

Thanks for uploading. As mentioned previously, you want to make sure you are NOT using the scaler. You have:
vga_scaler=1
video_mode=3 <-- Do you have a PAL TV? If so, do you know if it can also handle NTSC signals?

Change it to vga_scaler=0 and see what happens. If it won't sync, put this in your MiSTer.ini at the bottom then try to launch a core:
[menu]
vga_scaler=1

[SuperRAD]

Ah yeah, the original one has it, but the alt I use doesn't, so I don't think that's the issue. However, I did make sure they were matching and retested. I also disabled "video_mode", as I think that was just from testing changes to the .ini from on the mister itself. I believe it is an NTSC television, and not PAL. has a normal plug and everything. Large Panasonic television.

With the changes, nothing has been remedied. To further describe the issue, it's like the text on the OSD menu is vibrating back and forth slightly, what I described as a ripple effect previously. This carries over onto all cores. It's the entire screen and not just the text, it's just most noticeable there.

Did you try anything else on the component inputs?

A few things that might be causing this:
Velocity Modulation:

• In the service menu, I don't remember where, there is a setting for Velocity Modulation (VM). It might be called something slightly differently. Try toggling that setting.
• If your Panasonic is 24" or larger, you can pull the VM cable off the neck board inside the TV. If you don't know what you are doing, you can seriously hurt yourself, so do lots of watching of videos first on how to handle CRT repair. You should discharge the CRT before touching anything.

Service Menu adjustments:

• Some of the sizing and positioning controls have two different settings that affect the same thing in different ways like HPhase and HPOS. Write down all your settings before adjusting anything, and then try playing with all the settings in the service menu one at a time to see if the shimmering goes away.

Try my attached MiSTer.ini that I use with my Panasonic TV in my arcade cabinet with my Antonio MiSTer: (this is a bit older from something I emailed to somebody, but it might work).

[SuperRAD]

Unfortunately the .ini didn't fix anything and I don't have anywhere else I could plug in my Component cables at the moment. I can try the service menu at some point, but I would need to get a universal remote as I can do everything to get to the service menu up until i need to press the power button on the remove to actually open it.

[thorr]

You should get a remote. Meanwhile, if your TV is a larger model, pull the VM cable. It could fix it.

[SuperRAD]

It has the setting to disable it, so does manually pulling it matter? I tried and it didn't do anything. I will report back when I get a remote if S-Video doesn't fix my issue.

[thorr]

Yes, it still can have an affect. I just posted a link above.

[thorr]

Also, what cable are you using? If it has thin wires, it might be your cable. Here is the one I recommend: https://summitsource.com/eagle-6-ft-vga ... 5_9gdO70Aw

[SuperRAD]

Got it off amazon! https://www.amazon.ca/dp/B001O8C6HM?ref ... asin_title

Looking into it more, some Panasonic's have issues with components due to the Jungle Chip. that might be the cause here.

That cable has thinner wires. I am not saying it is the culprit, but I would rather have a better cable if it were me.

It is not the jungle chip. I am pretty sure of that. It could be failing capacitors. It's hard to troubleshoot without hooking up another device with component into the same TV. I have another TV that has a great picture with component input, but composite and Svideo have a bad picture, most likely due to failing parts in the signal path. However, I am not saying parts failure is causing your TV's issue, just a possibility. It could be the cable, it could be the VM, it could be where the TV is plugged into and something else plugged in nearby is causing it to do that, but probably not if Svideo is fine. Can you move the TV to a completely different room and try it there?

Sorry for the late reply, I was waiting for the adapter to come in.

I received the composite / s-video adapter from Antonio. I noticed that while I didn't experience shimmering as drastic on s-video as I did on Component, it was still there. So it seems like it helped, but didn't negate the problem. I tried S-Video, Composite and Component. Component has the worst shimmering, while the others have lessened, with S-Video being the best.

I do not have a universal remote yet to mess with the settings, but considering PS1 composite doesn't cause this issue on real hardware for me, I imagine it must be the Mister to some capacity. I don't think moving the TV would help since this issue is only on the Mister.

Is the MiSTer and the TV plugged into the same outlet/powerstrip? If not, try that. Also, unplug everything else on the same circuit. This will help isolate interference from other electronics. If you have one, you could also try a different power supply for the MiSTer. Also, unplug any USB devices, etc. from the MiSTer too. If none of that helps, reach out to Antonio Villena and ask him about it and tell him what you have tried so far to eliminate the issue.

[SuperRAD]

This is the only power supply I have access to atm, I bought it after the fact. I will search for the old one that came with it: https://www.amazon.ca/dp/B07S7Q9J8G?ref ... title&th=1

Everything is on the same strip and they are the only things plugged in. I will try without usb devices and contact Antonio.

[thorr]

Sounds good. The original power supply should work fine. You could also get a DirectVideo HDMI to VGA adapter as another test. https://www.amazon.com/gp/product/B00SW9JI9A If you contact Antonio, you can send him a link to this thread for more information.

Just an update, i haven't gotten a universal remote yet, but I did get the cable you suggested and it didn't fix the issue. Only step now is trying the remote or manually pulling out that thing you mentioned.

Pulling out the VM cable is quick and free, and if it was me, I would pull that cable anyway because nothing good comes from it. Just be careful to not touch anything else inside the TV and only use one hand. You can also try the Direct Video adapter to see if the problem is the analog I/O board.

Hey so the model of TV is a little different I think because I can't figure out which one is the VM cable.

Checking...

[thorr]

It's the red and white cable, and I think it can only be disconnected from the circled part. There are only two wires on that connector, correct? It is hard to see in the photo.

[SuperRAD]

No luck with the issue, but it did seem to make my picture way darker?

Bummer, I am asking in another group about it, which is where I got the info from. I will let you know if I hear anything more about the darker image. However, at least you have ruled that out. In the meantime, if the picture looks too dark, you can put the cable back on since it didn't help with the issue. It's possible that after disconnecting the cable, you need to make adjustments to the picture.

At this point, I would try the DirectVideo adapter just to rule out the analog I/O board. It's cheap. You might also have degrading capacitors in the TV, but that is harder to be sure of and to fix. Since it works with other video signals, I would start with the DV adapter.

[thorr]

Just heard back about the darker image: "well that certainly shouldn't happen. Maybe they somehow screwed something else up while they were inside. It's possible they may have accidentally bumped the g2 knob on the flyback transformer while removing the back cover."

I'm not exactly sure what that is, but where would I find it to fix it?
