Default DVD in glorious B&W ?????

My DVD player suddenly started showing everything (including the screen
saver) in black and white. It is connected to a big screen Sony with an S
video cable. It works fine except there is no colour. Colour on the set from
other sources is fine.
Is the problem likely with the DVD player, the cable or the input on the TV?
Thought I'd solicit some ideas before I wade into the bird's nest of wiring
back there to experiment.
Thanks

Could be one or more bad solder connections - try GENTLY wiggling each end
of the S-cable.

Also, make sure the DVD output mode is not set to component video. Usually, it's
set in one of the menu options.

FYI, the problem was a bent pin in one of the connectors. It must have got
squashed somehow when it was reinserted while I was re-wiring a couple of
things. Although I bought a new S-Video cable before I realized this (and it
fixed the problem) I believe the damaged cord can be repaired using a pair
of small needle nosed pliers to pull the bent pin straight again..
Thought this might be of interest to anyone suffering similar problems.
Tx to those who responded.

What you are seeing is luminance and sync, but no chroma. It could be
that the chroma signal in the S-video circuit is open, which in turn
could be due to a broken chroma conductor in the S-video cable.

See the 4-pin plug he

Or a cracked solder joint at the connector in either the player or the TV.

Are there composite viseo connectors on both DVD & TV? If so, try a jumper
there & report back.

Try a different S-video cable. Make sure the player is set to the
correct TV standard. Some players have a button on the remote, or
menu option for NTSC/PAL. If it's set the wrong way you won't get any
color on most TVs.
