Saturn RGB SCART voltage query

[speedlolita]

Well, as we all know PAL and NTSC-U/C | NTSC-J have different voltages or something on one of the pins.

Now I have two RGB SCART cables - one is for PAL and it works fine, and my JP one is fine - if my Saturn has a PAL power board in it.

Now, what would I have to do in order for my JP Saturn to have it's own JP power board and output RGB properly - because neither of these cables do at the moment.

Any help will be much appreciated.

Change the resistor that bridges pins 8 & 16 in the scart plug.

Okay, so I just keep playing about with those? Or is there a specific one you can recommend?

I've got a ton of resistors in my drawers so it shouldn't be too difficult.

I can't remember what I changed it for last time I did it, sorry dude.
First time I did it about 500 years ago I just bridged the pins with a wire in place of the resistor and it worked fine on my TV.

Ah okay, cool. I'll try that then and check what each cable has.

This was no problem with my old Trinitron as I used to be able to select "RGB" and it would work fine, even if AV1 wasn't displaying properly but my new CRT has no such RGB channel.

As mentioned, ideally you need 12v on Pin 8 for 4:3 switching, and then 3v on Pin 16 for RGB selection.
What you'd normally have is 9v to 12v going straight to Pin 8 from the console, then a resistor linked from Pin 8 to Pin 16 to knock the voltage down to around 3v, thus killing two birds with one stone.

So, there will be a resistor I have to remove and then it should be okay?

I'm not too sure about this.

The diagram here shows 5v available at pin 4 of the Saturn's A/V output socket. I think you can probably route this straight to pins 8 and 16 in the SCART plug (with no resistor), and it should work.

[speedlolita]

So I guess I'll just have to remove the resistor, I'll try this later, thanks!

[speedlolita]

Tried it to no avail.

I've no idea what's up with this, but it doesn't like it one bit.

Hell, I might just mod the hell out of one of my PAL consoles. :|

possible solution at the bottom of this link

"right, opening the spider rgb cable revealed a resistor between pins 8 and 16. sure enough, the 5v pin (well, 2.5v!) was joined to pin 16. joinging it to pin 8 instead (while keeping the resistor in place) caused RGB to work!"

I'm sure this guy posts on NTSC-UK too..

Why don't you just put a UK power board in the JPN unit? You already said it works fine that way, and then you won't have to **** about with a step-down.

Also, are you sure your JPN cable isn't RGB21? They don't have RGB Scart in Japan after all.

[speedlolita]

I'm not sure about it all really. But I got an RGB cable recently that works perfectly with the Victor Saturn I bought so I'm not gonna worry about this anymore.
