Introduction: S-Video to RCA Connecter

How to build a computer to TV converter or s-video to RCA
originally from link
Sorry i decided to make this instuctable after i made the converter

Step 1: Get Your Parts

An electronics store should carry all of these parts but your store may not.

1.S-Video connector link
2. RCA connector and cable ( I salvaged mine)
3. 470pf ceramic capacitor (I already Had One)
4. Wire
5. Solder
6. Soldering iron

Step 2: Build

follow the instructions on how to build it

Pin Out
1. Y Ground
2. C Ground
3. Y Data
4. C Data

First connect the Capacitor to pins 3 and 4, then connect 3 and 4 to RCA Data.
Second connect pins 1 and 2 to RCA ground.
third close it up and try it out.

Step 3: Try It Out

Plug it into your computer and your TV.
Of course your have to fiddle with settings.
First put your TV into TV\Video Mode.
Then on your computer right click on your desktop and select Properties.
Next select the settings tab and click advanced and turn your display to TV.
You also may need to adjust your resolution settings.
this project will work but wont give you excellent quality text but is good for movies and other media.

works perfect, didn't use the capacitor, not sure what it would do to help the picture. More then happy with the quality on a 55" plasma. Thanks de-evolution

Picture Just wite & Black, what should I do?

If your video is b&w then you used the wrong wire. Look here

If you use pins 3 and 1 you will get b&w.
If you use pins 4 and 2 you will get color.

I have a problem it displays Black and White picture only not color please help why ??

Can someone please tell me why i need a capacitor? ive seen this done without a capacitor, and it dosent seem to hurt anything

We work on Polycom Video Conferencing units and if you have an auxilary video source that you would like to add to the system. You need to connect it to the S-Video connection. The same happens as with "GAUZZ". Due to the Y and C not being fused together properly. I'm not sure if the cap will work, but I'm curious to try it. We recommend that you use a scaler instead of this cable. Even though we've seen it work.

where to plug rca connector

kane89 made it!(author)2011-03-19

does it matter the voltage of the 470pf ceramic capacitor
i have found a few on but not sure which to get

firebirdfantom made it!(author)2010-12-27

could a electrolytic capacitor be used in place of the ceramic?

leifforrest made it!(author)2010-11-19

There are lots of mini-din connectors, S-video is a 4 pin. See this wikipedia link for a run down.

gauzz made it!(author)2010-10-08

Helpp please!!!

I did a cable without the capacitor but it only works for less than a second, then everything goes black.

Do you believe if I use the cap it'll work? Also in what kind of electronics I can find one? I cant find a place that sells a pf anything.

gauzz made it!(author)2010-10-15

So... I finally did it, the cables were not connected well so I fixed it without the need of a capacitor.

Worked for me without the capacitor as well.

hey dose anyone have the coding for a VGA cable

Do you mean the pinout? See Hardware Book.

Hi, I have made my 4 pin S-Video to Composite...I think thats what it is....cable but I have to test it yet...I am catching up to all the ideas I got from here on, I am having a great time...fooooooood!

TCPMeta made it!(author)2009-08-11

All you need is Pins 2 and 4. Ground and Color (Chrominance). Pin 3 is for gray scale video. So with people using 2wire cables just put red to RCA Data and white to RCA Ground. The capacitor is not needed but it helps to clear up the picture a bit, kinda like a weak drop amp.

kidapx made it!(author)2009-07-14

I have also run into the same problem as jbulldog my S-Video only has 2 wires, a red and a white and inside each wires is another wire. Any idea which would work as ground and which works as the video feed???

don't need a Capacitor it´s work whit out it

are u german?

rcbally made it!(author)2009-03-03

is it possible to do the 7pin to give comp video and audio on RCAs, if so how?

itstemo1 made it!(author)2008-02-12

Do it work the other way around? RCA to S-Video?

Hey, I'm assuming most of you here are from America? What with the Radio-Shack and all! Just wondering how common a 9 Pin S-Video Cable is over there??? EMPHASIS on the 9!!! lols I'm from Australia and for the life of me can't find a 9 pin! On to my main point!! Awesome Instructable, have tried a similar thing except with 9 pin. failed epicly. So yeah, if 9 pin S-video is common over there would be grateful to know!! Sedge

jbulldog_11 made it!(author)2008-09-09

I have a radio shack s-video cable, and it has a red and wire only, and then a pink inside the red, and a clear inside the white. Do you happen to know which cable is which?

maxpower49 made it!(author)2008-06-12

does this work for pc or does it only work for laptops

DIY++Dave made it!(author)2008-03-05

do they sell that capacitor at radio shack?

acaz93 made it!(author)2008-04-15

They do , they are in a drawer

DIY++Dave made it!(author)2008-04-15

Thanks, I'll get 1 tomorow.

DIY++Dave made it!(author)2008-04-18

just finished it this evening

acaz93 made it!(author)2008-04-18

it worked all right ?

DIY++Dave made it!(author)2008-04-23

yes, it worked

Could you make this with an ipod cord? And if so, how?

stxera made it!(author)2008-02-04

thanks for the instructions, I'm yet to salvage a capacitor that works.. it does work without a capacitor - but I'm not sure its best that way.

munchman made it!(author)2008-01-08

It would be easier, cheaper and safer just to buy one...

vanmankline made it!(author)2007-12-25

Through other sources I've found 400 pf - 10 nf capacitors would be acceptable (with ~470 being ideal). However, I have been unable to find any. Do you have any suggestions as to where I might be able to salvage one from?

hondagofast made it!(author)2007-12-10

I didn't see the schematic at first, but this is a very useful instructable. +1!

paulgeering made it!(author)2007-12-09

Would I be right in thinking that this will only convert an s-video signal to composite video but will not convert in the other direction (composite -> s-video)?

Zava made it!(author)2007-12-09

You would be right, it can step down the video quality from an S-Video signal to a composite one, but it can't step it up, a composite video connector simply can't accept the higher quality signal. Good instructable, and good idea for a project, but I would suggest some background information into the functions of composite and s-video, and maybe discussing how it will effect the video quality more in depthly.

good instructable i guess, should have more stuff though.
