TV-out shows black & white on TV

[JekyllSan]

Hi everyone,

I have an AMS 968L barebone system that's running perfectly, the only thing is I've been trying to connect it to my TV through the onboard Intel graphic chipset with both S-video and composite outputs. It appears that both connections to my TV show black and white picture. For the S-video output, I used an adaptor that converts S-Video to composite video jack. I've never experience this before so I'm asking for advice or answers to solve my problem.

Any reply is certainly appreciated.

Thanks

Possibly two problems! (or more).......

1) Your TV needs an auxillary input that supports S-Video (the Y/C chanel, not a normal AV chanel) as S-Video consists of two streams, one stream for B+W and one for the Colour to put it simply. The TV will then convert both signals into one, so you get a sharp colour picture on the TV.

2) If converting S-Video to rca then the cable re-mixes the two S-vid chanels to a single chanel that the telly reads (similar to the normal video signal on a co-ax: aerial cable ). But some cables are made on the cheap and may 'lose' one half of the original S-Vid signal. Plus cheap S-Vid cables can do the same (lose the colour side).

3) There are probably many other answers (faulty hardware etc) but the two above are the most common.

So use a telly that has S-Video inputs (the Y/C chanel) or use good quality cable. By the way keep rca runs as short as possible as the signal strength is lower than S-Video (plus its never shielded as good and you get the wavy line effect).

If your in the UK or Europe you can get SCART adaptors with rca (audio L+R and Video) and s-video inputs to make thing easier (especially if the S-Video input is stupidly positioned on the front or side of the telly as it looks a right mess).

HTH

Maybe someone else can add some more.
