Why is the s video output from my Matrox Mini using y cable into blue and red not giving picture ? Into green and red I get B/W picture only.

I have never herd of a red and blue combo but, The three, red, blue, and green are "component" cables. Hopefully your DVD player has a red, blue, adn green component out, not to be confused with red composite out. Composite cables are yellow, red and white, and, your tv has componenet in. The component cable will give you the best video quality. When installing make sure they are inserted all the way but twisting and wiggling or you will have a bluish, grenish, etc. picture. The composite cables give you the video only, so you will have to provide the audio. Audio can be achived using composite red and white or digital optical.If you second monster cable is red and white you can probably use those To go from "audio" red and white out on DVD to audio in red and white on tv. You must use the same audio input that corresponds to you video input.

Have you tried using standard RCA AV cables? yellow-red-white - to TV. Or have you tried using an S-Video cable (a 5-pin mini DIN plug) between your DVD player and TV? if your TV has S-Video input, and your player has S-Video output, a cable for this should be easy to obtain and connect. Not expensive either.

Your TV should automatically detect the connection of S-Video (if it has this feature). S-Video is better quality than standard RCA yellow AV cable. (you can leave the existing component video connected)

You can also check your DVD player 'setup' maybe it is incorrect - make sure when using component video (red-green-blue) to set the player's output to progressive (for a TV that supports it) - unless it is already set to this.

If everything in the setup menu checks out OK, go with the cheap and easy S-Video cable suggestion. Radio Shack may sell these.

Use three RCA cables, yellow, white and red to connect DVD player to TV as shown in the diagram below. Connect yellow to yellow and white to white. Connect red to red. Select on the TV, the A/V input where the DVD is connected using the TV remote control. Power on TV and DVD, place a disc in tray of DVD player and press PLAY.

Hello
If you see the picture in yellow colour, means that there is no blue colour output from the video drive section in your tv, Yello is the mixtrure colour of red and green. Green is actualy there. blue colour is absent.
To detect this fault, you must open your tv. Just look in to the video output section, can be located at the picture tube base card, which is plughed into it diretly. See for any loose soldering points there. Check whether transisotors are used for red, green and blue output stages, or an Ic or three seperate Ics are used for this purpose. Anyway, blue catode of your picture tube pin gets a hig voltage, and so the blue emission is absent. You just check the voltages at red,gree and blue catodes, at the respective picture tube pins, which can be taken at picture tube base card. All of these three pin voltages must be somewhat equal to each other. In your case, no voltage at blue cathode will be higher that the other two. Check for the reason. It may be due to an open video output transistor [blue], or an Ic, of one Ic if used for the three colour outputs. Check and replace the same, will rectify your problem. Ok

There are two ways to connect it.
1. The cable that came with your xbox should have two sets of plugs on it. One being the red, white, yellow and the other red, green, blue. You need to plug the red, green, and blue plugs into the tv with the same color plugs. You will also have to plug in the red and white for sound. The yellow plug is not needed. There will also be a switch at the base of the cable near the xbox. That needs to be set to HDTV. If your cable does not have the red, green, blue you will need to buy a cable that does have them.
2. You can use an HDMI cable. With that all you need to do is plug one end of the HDMI cable into the xbox and the other into the tv. Not all xbox's have the HDMI output though. If its new i should have it on the back of the xbox near the normal tv output slot.
If you use the red, green, blue you will have to set your tv on the component channel. If you use HDMI the tv will have to be on the HDMI channel

You say the component video is no good? Well this usually happens when it is wired up incorrectly, Ensure you have the right colors in the right jacks at each end, it is real easy to get mixed up... make sure Red goes to Red, Blue to Blue and Green to green, all alongside each other, NO ALSO using Component you MUST also run 2 more cables for the Audio, they are Red & White NOT the Red from the "Other" Video input, BUT the AV Red & White jacks, beside each other on the units. So all in all there are 5 cables taking the Video, 3 R, G, B. + The Audio, R & W.

The series of the cable should go green red blue into the back. if you put the green in the red and the red into the green it give the TV a red base to go off of for the picture so everything is red. The reason the green cable won't is because it transmits a black and white picture which allows it a nice base to add the green and red to.

you may need to change the settings for video out. If the video is set to Progressive scanning and P Y R (green, blue, red cables) then it won't display video using the yellow cable. turn progressive scanning off and maybe try to select S video output. that worked for me. of course u mite have to have a tv that has both yellow video input and blue green red video input to see the menu to start with.

sounds like you are using componant cables.[ red,blue,green on the right side in back of the cable box for the picture, & red & white cables for the sound.] make sure the red & white cables are connected to the middle white & red outputs of the cable box to the tv's red & white inputs, not outputs. hope this helps.

very simple , just made sure dvd output hooked to the input of your tvs and same color ,jack to jack,you know, yellow to yellow,red to red ,white to white.But I suggest you use a s-video jack(all black). instead of the yellow composite ,or RCA jack,which give you a better picture,and if you have a the component jacks (red, blue , green)on both machine , that will give you the best picture, but remember , you still have to connect the red(right channel,+))and white(left channel,-)cable to have sound coming out from your tv.You will need a s-video cable or component cables for those option I suggested.
