Hi folks- all of a sudden, I have no color coming from the S-video port
on this player. Color is there using the composite video port. Have
looked at the back of the PCB in that area with a microscope, checked
continuity from pin 4 (all pins, actually) through the traces- several
resistors and one 100 nF cap appear to be all good.

Any ideas? I'd love to see a schematic of this unit.

Are you sure that it is the dvd output and not the tv s-vid input?
Did you try another s vid source to your tv?

Hi, James.
Yup, there are two other S-video sources running to the TV through a
Sony DA333ES receiver; they both work fine. And I've switched things
around to eliminate the receiver switching circuitry. Haven't put a
'scope on the outputs yet. Could have missed something; gonna take it
over to a friend's place to doublecheck tomorrow.

Check the settings in the DVD menu, it may have defaulted to the wrong
output.
Or some units have a simple switch on the back of the DVD player. Dani.

Have you checked to make sure the output mode of the player is set to
S-video? Many DVD players have a switch, or menu setting for
S-video/component. In component mode it will only output the Y signal
from the s-video.

Even if it's still set to S-video, it's worth toggling the setting
just in case a software bug caused it to switch to component mode
while still displaying S-video mode in the menu.

This may sound too simple but...
You said you switched around various inputs but have you tried switching
the s-video cable?
Sometimes they just develop an internal break for no apparent reason.
Always try the simplest thing first.
