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.

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.

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. Andy Cuffe

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.
