Title: Toshiba 32A10 won't display S-Video
Post by: ulera on August 09, 2012, 09:38:40 pm
Okay, I know this isn't really console related... but I could really use some  :help:

So I dropped my old Sony Trinitron I used for old game consoles, I loved it because it had several hookups of every sort so I went out to a garage saleing today to replace it.

I found a nice Toshiba 32A10 and bought it, when I hooked it up however I noticed none of my consoles connected via S-Video displayed a picture (all blank screen). All of the other inputs work, but not S-video which is a problem since three of my consoles use it. What could be the issue here?

P.S. Consoles hooked up via a composite connection also will display a blank picture is an S-video cable is plugged in, even if it isn't connected to anything.


Anyone know why my TV would have such an aversion to S-Video?

There might be a setting you need to adjust in the menu system. With one of my older CRT TV's you need to specify whether composite or s-video is being connected/used.

I checked the menu and it didn't have anything like that, and if that were the case why would the composite inputs quit working when an S-video cable was plugged in?

Downloading the TV's owners manual, I've discovered that it says not to have composite and s-video hooked up at the same time. I tried that though and it still won't work with just the s-video plugged in.

Do you connect it via s-video because you want to, or because you need to? If it's for the latter reason and you don't find a way to make your TV accept s-video input then you could always convert the signal to composite:

Connecting it via s-video would yield a better picture, but if all else fails...

I had an epic fail. There was just a loose connection in my switch box. I still have to manually change what cables are connected though because the TV will always default to using the s-video cable even if nothing is using it and I'm trying to use my AV Famicom >:(

That's great! If you don't want to switch cables all the time then you can simply connect the composite video to both the Y-pin and C-pin in the s-video connector. You won't get any picture improvements, but at least you won't have to switch the cables.

Hard to tell if it has a 470pF capacitor on the composite video line (required for s-video to composite conversion, but shouldn't be there for composite to s-video), but I believe it would work either way. At least it's cheap! :)

Great. If I can find a s-video splitter (which shouldn't be too hard) I'll order one.
