2nd April 2005, 05:55 PM
Hey all, i was wondering if anyone knew or had the same problem as this?

i have a Radeon 9800 PRO (PC Flashed) it works perfectly except the S-Video output is black and white. i have changed all the settings in ATI Displays, and have tried diferent TV's... all resuslts the same. any help?

Is the S-Video cable of high quality?

Cabling can make for some outstandingly strange output.

It's likely it's a cable problem.

Check each connector - are all four pins present at each end?

If not, there's your answer.

Also try a shorter cable. It should definitely be under 4 meters.

Definitely try several cables that you know work properly before suspecting hardware.

i tried plugging my powerbook into a friend's TV - it came out black and white. Maybe try it on a different TV?

i've had this problem before, it was the cable that goes in between the devices fault... replaced it and hey presto, colour again...

ATI often offer frequent updates to their ROM sets and ATI desktop software - have you updated both to the latest?

I use a cheap, thin Jaycar 10m SVideo cable to my TV (from an EPIA-based HTPC), and it's fine. I've encountered problems with the TV not setting the right PAL or NTSC output. Some (read: cheap) TVs I've plugged the machine into just plain refuse to output to colour, regardless of each setting I've adjusted. Wondering if that's the problem - it's not properly set to PAL/NTSC on your TV.

oh ok thanks, i thought for a sec a found a fault in my flashed 9800 :) will go to some place and get a decent cable. thanks :D

My first reaction is to agree with Byrd.

Most recent TVs have some option to set the colour mode to PAL / NTSC / AUTO

NTSC signal on a PAL tv comes out black& white.
Foreign PAL signal on an Aus PAL tv also comes out black & white (or in some cases the hue/saturation is screwed up). Casued by incorrect colour carrier frequency (different countries transmit colour information at different frequencies).

If you've tried different TVs/cables, then this is most likely the problem.
Have you got an S-Video to Composite converter plug (comes with most videocards)? You could see if putting the signal through a composite RCA cable helps.

If its not the cable. I'd like to think that the issue is more to do with said NTSC and PAL.

I know with my TV (its a Loewe) when there is a NTCS signal present, the screen will go black and white for a second, then flick over to colour.
