RGB cable problem. HELP!

[cgun]

I recently got a RGB-cable for my neo but it does not work properly.

I get a red flickering image. The screen seems to tilt in multiple directions very fast, so you can´t see anyhting other then small pieces of the image. The Cable is not fully pinned. 4 pins are missing and i don´t know if that´s right. All of my RGB-cables for other systems i fully pinned.

Please help, i can´t stand RF output!

The picture you described is due to the sync not being connected check inside your scart plug the sync should be on scart pin 19 or 20, the sync is connected to the composite output of the neogeo, so you should have R,G,B ,Comp(sync),sound(mono),earth. that is six connections in your scart plug....

 

[cgun]

Ok, i don´t know about that kind of stuff. My electronical skills is somewhat limited. Is there somewhay i could get it to work? And could someone expalin it for me then?

 

[cgun]

Well, if you count from the upper row. The following pins are missing...

15,16,18,20

IIIIIIIIII
IIII I I

Like that... hope it helps

We have to agree on the numbering. Check here:

<a href="http://www.fedingas.lt/hdw/co_Scart.htm" target="_blank">http://www.fedingas.lt/hdw/co_Scart.htm</a>

Note that one row is for even numbers and the other for odd numbers.

 

[cgun]

Ok, then the pibns missing are...

2,6,10,12

More info > I get no sound, no green and no blue. And as said beofre, the image tilts.

 

[MKL]

Pin 2 is "audio in - right" which is not needed as the Neo outputs mono. Pin 6 however is "audio in - mono" and that's why you get no sound.

Pins 10 and 12 are not needed anyway. Green is pin 11 and blue is 7.

 

[cgun]

Ok, but why doesn´t the image show then?

My AES is a 60hz modded PAL unit. And it worked fine with the usual Scart-lead i had before.

Could it be that you need a SCART cable and not the RGB one? I'm not real technical, but I know that there is an RGB and a SCART cable for the Neo and they both look very similar, with only some differences in the pins.

I had a SCART one and tried to hook it up to my XGRB2 and had similar problems to what you described. What I needed was an RGB cable. When I got that, it worked fine. I really couldn't tell the difference between the two cables when I laid them side by side, so you may have the wrong one and not know it.

BTW, don't use the incorrect cable anymore!! Using the incorrect cable ended up breaking my XRGB2 . Luckily, NCSX repaired it for free. So stop using that cable and go get the correct one!

Ok, first of all. Is your NEO System Jap or Pal, if it is Jap and you are using a RGB cable, the your TV must be able to display 60HZ through RGB/SCART output. If not what uses to happen is that the image move from up to down very, very quickly.

Otherwise could be that one of the blue, green resistors through which the RGB (Red, Blue Green) image is displayed is dead. In that case you cannot display colors properly through RGB, but you will through RF and AV or even S-VHS I guess.

The fact is that your problem seems to be a mixture of the both above-mentioned, so please be more specific about your TV and Neo characteristics.

As for what Galford said, and according to my experience, here in Europe there is no problem using a RGB or SCART, both means the saim, just your TV must be 60 Hz compatible.

OOOOPSSS, SORRY, FORGET ABOUT THE ABOVE POST, READ THIS PLEASE:

The xrgb+ is a japanese device and needs a japanese RGB cable. The connector on this cable is identical in shape to the Scart euroconnector but the pins are different, see here:

<a href="http://www.gamesx.com/avpinouts/rgb21pinj.htm" target="_blank">www.gamesx.com/avpinouts/rgb21pinj.htm</a>

They have something in common though: on both the red is on pin 15, so if you have a japanese RGB cable this might explain why you don't have green and blu (as you said above). Try to get the right cable, e.g. from <a href="http://www.neoayato.com" target="_blank">www.neoayato.com</a>

Hell no! Scart may be wired in different ways: it can be composite, RGB or even S-Video...a lot of problems arise from the incorrect assumption that Scart = RGB...

 

[Pep]

MKL,

Cgun was asking for his Neo System, not for a XRGB, it has been Galford who has spoken about XRGB.

Thanks for your clarification in relation with RGB/SCART, I assumed they were the same because they have the same shape, I was talking about the external shape, but it looks like RGB/SCART do not mean the type of wire or tool but the type of displaying method.

 

[cgun]

Great, some help finally...

OK... Heres all the details.

My AES is a 60hz modded PAL unit (european). My television is PAL, it can handle 60hz and NTSC.

Can it be that the system is modded, the mod was made by cutting the one of the PAL-resistors. Which made the game show in 60hz.

I previously owned a regular scart-cable, and it worked fine. RF works fine as well.

 

[cgun]

I got the cable from !arcade! BTW. It was reffered to as a RGB cable.

Yes it's a known mod. But with the proper Scart-RGB cable you should have no problems.

So you no longer have that cable now?

Again, my suggestion is to get a real Scart-RGB cable: from what you said above it's evident you don't have the right cable.

Note that there are a couple of RGB cables in the neostore but since they're just called RGB I can't tell if they're the scart type (that suits you) or the japanese type (identical to scart only in shape, probably the one you have now).

The fact that you got that cable from !arcade! (Canada) sugests that you have indeed the wrong cable: a real Scart-RGB cable is stuff hardly available outside Europe.

MKL > Yeah, i think i know what the problem is. I propably have a JAP RGB cable.

I took a look at arcade´s site and they didn´t have a european RGB. I made the deal directly with ray via e-mail so i didn´t know that....

But he knew your from europe and he must also have known that that cable doesn't work on European TV's...if he's a tech guy he must have known!

<img src="graemlins/ohno.gif" border="0" alt="[Oh No]" />

 

[cgun]

Yeah, he propably knew that. But i wasn´t very specific since i didn´t know there were two different RGB-cables. We will see, if i don´t get a refund, check for a japanese RGB in the selling forum.

 

[MKL]

heh...hope you'll make it clear it's not a scart cable...

 

[Galford Forever]

You're welcome

 

[cgun]

Thanks for all the help guys. I´m getting a full refund. And some new neo geo knowledge.

 

[Pep]

This is quite weird because I have a cable (SCART/RGB shape), bought in local neo store to display RGB and that displays in flawless RGB, it works fine with my JAP machine, but I think it also works fine with a modified PAL system I already own, I could check it if you want

 

[cgun]

Pep > I think i missed your point, sorry.

The cable that you got there would propably be a EURO RGB then. If it works on your PAL-TV.

Another thing, do the cables really fit the MegaDrive (model 1). At videogameimports for example they say it does. My RF does not...
