Title: S-video = black and white.
Post by: paigeoliver on September 23, 2005, 08:45:02 pm

I accidently knocked my laptop off a table while it was hooked up to my TV via s-video (yanking the cord out of it). Luckily the laptop was not harmed, but when I plugged it back into the TV it gave me a black and white image.

Any thoughts?

Knock it off the table again?

Sounds like your cord may have been damaged as it got yanked out.

Can a damaged cord do that?

IIRC, S-vid seperates chroma and luma signals.  No clue where the sync sits, but it sounds like the chroma signal is gone.

Check continuity 2-2 and 4-4 ?

Last time I dropped a laptop with a cable plugged in, it was the socket that took a beating, not the cable.

Ok, thankfully it appears that it was the cable that was ruined and not the port. I tried the cable with my DVD player and it also came up black and white.

Nice to see it works. I charge $40 an hour for over-the-internet consultations by the way.  ;D

I just ordered a new 12 foot cable. The 3 foot cable I was using was the reason the laptop fell in the first place.

Exactly. And seperate grounds for both signals.

Sync is on luma.
