Radeon 7500 to TV (7pin S-Video/SVHS to composite or SCART..

[Guest]

Archived from groups: alt.comp.periphs.videocards.ati (More info?)

I am trying in vain to connect the output from my Radeon 7500 in a
Dell Inspiron 5100 laptop to my TV.

I'm on my third cable now (bought from various places), and this one
finally gives a picture, but it's black and white.

I've decided I want to make up my own cable to sort this out once and
for all and stop wasting any more time trying to source the right
cable.

With information from
http://tvtool.info/go.htm?http://tvtool.info/english/cablefaq_e.htm I
did a pin out on the cable I have now that is producing a nice black
and white picture. On this cable the S-Video end has 4 pins, to a
SCART with a switch to change the direction. With the direction set to
go from S-Video to SCART, I found that pins 3 and 4 on the S-Video are
connected to 15 and 20 on the SCART, which seems correct?

I didn't test to see where pins 1 and 2 from s-video went, but this
was a medium quality cable from Maplin and presumably they are grounds
and would have been connected correctly (?)

So what do I need to do to get a colour picture? I've spent ages
googling, and can't find a definitive answer.


background info:

- TV is few year old Grundig with 2 x SCART in and 1 x Composite in
- I tried a simple 7 pin S-Video to composite converter which didn't
work (which with pin identification as per
http://www.weethet.nl/english/video_connect_pc2tv.php#svideo has pin 5
connected as the composite, although this page says pin 6 carries the
signal
- I tried another S-Video to SCART lead - cheapy off Ebay which didn't
work
at all.

Thanks for any help/advice. I'm ready with the soldering iron, but if
anyone knows a cable from Maplin or other readily available source
that will definitely work that's fine too.

This is all the information I can give you.

Old UK TV's won't accept an NTSC signal from S-VHS and display in black and
white, so the problem is down to your TV being too old. Even though the TV
has SCART on it, it still won't display correctly.

This principal will even work on a PS2, put in a UK DVD and it displays
properly, but if you put in an American one it will display in black and
white due to the fact it's an NTSC DVD.

A while ago graphics cards producers realised this and included an S-VHS to
COMPOSITE adaptor, (I admittedly have two of them and I need one myself, but
it's about 600miles away from where I am right now.)

Best bet would be to search for the adaptor online, (you may have better
luck on ebay, or someone might be nice enough to let you have theirs.)

Good hunting,

Daz.

Maplins. Item:QM52G

That's the one.

Daz,
Thanks for the reply - it is a PAL TV, but with the bog standard
Radeon drivers I can choose the formats and get it to output in PAL
and it looks exactly the same as when I choose NTSC - TV isn't that
old and allows me to manually choose from various NTSC/PAL options or
auto detect and I've got it on auto detect.

As I said, I've tried a SVHS to composite adaptor, but not sure that
the pinout is correct, and there's also at least four different
versions of these adaptors to accomodate different ways that video
card vendors can send their output to the S-VHS connector, which is
why I was after some specific Radeon-7500 help (maybe even specific
Radeon 7500 in a Dell Inspiron help. urgh).

The local Maplin kids are gonna get annoyed with me for taking stuff
back all the time but I might give that adaptor you suggest a go. If
it's the kind that combines the standard luminance and chrominance
pins I haven't tried that option yet and it might work.

Check out http://www.s-video.com/. I've tired various s-video to SCART
adapters and they've always been in black and white. I've bought two
cables from the above site and they've worked flawlessly (S-Video to RCA
Composite that is ).

James,

Trust me on that one, the adaptor will work. I myself was confused about
the fact you can select between PAL and NTSC output, but yet still coming
out black and white. I think because you have the S-VHS cable plugged in,
it assumes the output will be to a NTSC TV, (it's an American thing
apparently.) No matter how I fiddled and prodded with the standard S-VHS
cable, it wouldn't work in colour. But to use the adaptor the output is
forced into a PAL signal a UK TV will understand.

As for the different S-VHS adaptors, they're a standard so there won't be a
lot of difference on pin outputs. They should all do the same thing.

Daz.

I got my adaptors free with my old VooDoo 3000 and my old NVidia 256 DDR.
