TV-out problem on Toshiba laptop

[andmoreagain]

Hi everyone,

i have a Toshiba Satellite laptop with a Mobility Radeon graphics chip
and i'm having trouble getting the TV-out to work. I have an s-vhs cable
from the laptop into my TV via a SCART adapter but the picture is in
black and white. i've played around with the ati settings to no avail.
also, when i play video files, they don't appear on the TV - only on the
laptop screen. Is it likely to be a problem with the laptop, the
cable/adapter, or the TV? the TV is a cheap one but it does connect OK
via SCART to my digibox and DVD player. the cable is also cheap but I
would have thought it would be OK. any help appreciated!

thanks

Your TV most likely does not support s-video. You can connect an s-video
cable via scart, but it won't work if the TV doesn't support it. The
picture will be black and white since the TV isn't capable of receiving
separate chrominance (colors) and luminance (brigthness) signals (which
is what is carried via s-video). Only the luminance part is shown, hence
b&w.

There might be an option somewhere in Mobility Radeon TV-out settings to
change the tv-out signal to COMPOSITE. You'd still use the same exact
cables you do now (the s-video) but the signal carried would hold both
color and brightness information on the same pin.

If not, you could try to find an S-Video to Composite adapter on a local
electronics shop. It shouldn't cost too much.

PS. Do you have different AV channels on your TV set? For example, my TV
set has two SCART slots and corresponding two AV channels AV1 and AV2.
But only slot number two supports s-video, and even then I need to
select a third AV channel AV2-S to get a color picture (at the same time
channel AV2 shows a b&w image).

that sounds likely. its a cheap-o tv - it only has one scart input and
no actual s-video input. i'll try looking for an s-video > composite
adapter. thanks for your help

one last question, if the TV doesn't support s-vhs, will an adapter make
any difference? i mean, won't the signal still be the same however it
plugs into the TV - it will still be an s-vhs signal, not a composite one?

Well, I guess I should've said S-video to Composite CONVERTER... It
should be short cable with an S-video plug in one end and and an RCA
plug in the other, and some dongle in between.
