RGB Component Connection problem

[ou mba tutor]

Hi,

I have bought a Sony BluRay player (S350) and have connected it to my television using the RGB component feed. My TV does not have a HDMI interface.

When I select the source the picture has a very heavy green tint.

I have swapped the cables and the problem remains and I have tried the yellow AV connection and the picture quality is fine.

Any advice?

Thanks,
Nic

Classic symptoms of YUV component signal being fed into a RGB input (or vice versa). Check that the players component output is set to RGB, not YUV, as they use different "colour space" coordinates.

If you have an RGB signal into a YUV input then you get a magenta tinted image.

Thanks LCDMAN ....

I've looked at the manual

it doesn't mention YUV - so I'm not too sure how I can check the RGB setting.

If you have not got a HDMI interface on your TV, has it got a COMPONENT input facility i.e Red, Yellow, and White input leads (jump leads, I call them!)
Your BlueRay may well have the output facility and if so you could try this method of connecting the two together.

Quickly looking at the manual, it seems RGB is only available on HDMI output. The alternative is to use an S-Video connection if your TV has it (separate audio cables needed) or a video cable from the video socket (below the S-Video socket) to the AV video socket on the TV.

Redman41 - Red, Yellow and White phono (or RCA) connectors are NOT component - they are Red=Right Audio, White=Left Audio and Yellow =COMPOSITE VIDEO.

Component video is YUV format utilising the colour difference signals mathematically derived from RGB in proportion, however RGB is often widely referred to as component video (even though it isn't). They use totally different colour space co-ordinates.

ou mba tutor, thanks for the manual link.

The component output is YUV (lalso called YPbPr or YCbCr) - look at the manual p17. This can't go up the RGB input of your TV. Looks like you can't set it to RGB either.

As I said in my post above, RGB isn't the same as component (which is YUV or YPbPr or YCbCr) although many confuse the two as they both use plugs coloured Red, Green and Blue!

I stand by my original diagnosis.

Your only options are to use the composite video + stereo audio (Red, White & Yellow phonos) or S-video and stereo audio but there will be little difference in image quality between those two.

What you certainly WON'T have, without a HDMI or component connection, is any HD images, despite it being a blu-ray player!! The composite and S-video outputs only give "normal" standard definition images at 576i resolution.
