I have a Sony watchman model FD-20A, there is a jack on the side labeled video in. It is the size of a standard 1/8" jack, however when I plug my RCA to 1/8" splitter cord into it all I get is video and no sound. Do I need a special cord, or is this input only for video and not sound, and if so why would the designer do that?

A raw video signal does not contain audio. Perhaps the input jack is a "stereo" version with, for example, video on the tip connection and audio on the ring connection. Just a thought.

I have several of these but can't put my finger on them right this minute. I suspect that it is just a jack for video only, not video and audio. If it were both, I really think it would be labeled the same. I will see what I can find later today.

A screen shot from the auction site...

Why would Sony put a video only jack on this?

It's probably composite video only, for use as a monitor I suppose. It would surely be labeled A/V input if it were both.

A monitor would be my guess as well, and that feature was apparently somewhat short lived. I have an FD-40A, and it doesn't have a video input jack.

It's labeled Audio/Video In on my FDL-310.

The FD-40A I used to have had an RCA-looking jack on the side which was labeled A/V IN. I found a picture of the mating plug meant to fit said connector, and it basically looks like a regular RCA plug with a 2-conductor 1/8" plug where the center pin would normally be. Here's a picture of the adaptor meant to fit said plug:

I'm pretty sure the jack on the FD-20A is, as indicated, video only. No idea exactly why they decided to do this, but they did. They also included an antenna in jack on the top, at the least.

I have a Zenith BT044S that looks to have the same connector as Adam is showing.

Not sure how it is related to a Sony, as it claims to be made in Mexico, which Zenith indeed had a factory down there.

Perhaps the same CRT?

I have a Sony 8mm digital video camera and it has an 1/8" jack but it's labeled A/V input, the connector is Red. White Yellow RCA jacks to 1/8" plug with an extra contact for the video.

It wouldn't surprise me if Sony OEMed the set for Zenith, as Sony also rebranded their Betamax VCRs for them. I have a Zenith "Video Director" VR-9000W which is little more than a Sony SL-5400 with different trim. More on Zenith's rebranding of Sony Betamax VCRs can be found here.

Other companies also made OEM stuff for Zenith; a friend of mine has a Zenith VP-2000 Selectavision CED player which was made for them by RCA. And according to this page, JVC made the first VHS VCRs sold under the Zenith name after they abandoned the Betamax format in the mid '80s.

Yeah, I worked for a Zenith dealer first part time between August 1984 to May 1985, then full time between March 1986 and May 1998.

I'm quite familiar with the Sony made Betamax Zeniths and the JVC made VHS Zeniths, then around 1990, they transitioned to Goldstar made VHS decks.... which were a mess...
They were clearly marked "Made in Japan" or Korea.

This TV is marked Mexico, so I suppose they could have bought the components from Sony and assembled them in Reynosa, but why ad the extra step?

Anyhow, kinda getting off topic here, so I'll stop now.
