Problems with Nintendo 64 S Video cable on LCD panel

[humbert]

I've bought a cable for Nintendo 64, which combines both S Video and Composite cables. When connecting to my LCD panel the picture is "dotted" (every other pixel is black), the same thing happens when connecting to a Plasma panel, is it caused by the cable?

So the first thing I'd try is switch to the composite video cable. If the problems go away, then there's likely a problem with the S-Video portion of the cable. One of the pins might be bent, or the cable might be improperly shielded. With a bent pin, you might be able to fix it, but you'll likely have to buy a new cable.

Composite part of cable works. Thanks a lot for the answer.

I don't know if you are or not, but do not use the two cables in conjunction, either S-video, or Composite. But I'm assuming you know that.
Hopefully you've already fixed your problem, I love my Super Nintendo, Nintendo 64, and Gamecube in S-Video. Text clarity and colors are worth it alone.

I've had the same problem using (2) different S-video cables from the same eBay seller. So.. it's possible that the cable is cheaply made. No ferrite cores on any of the cables but it might be cheaply manufactured. I've hooked up the same cable to my SNES, N64 and Gamecube with the exact same horizontal lines. Composite (red/white/yellow) work fine as far as what you'd expect from a good set. I don't think it's the 37" LG LCD television as I've got my Saturn hooked into it using an S-video that looks great. Ironically, I just picked up a Dreamcast S-video cable from an eBay seller and it also has the same display problems as the (2) Nintendo cables. I have searched the net looking for issues with LCDs like video lag etc. My set has a 'game mode' but that doesn't do anything at all other than change the backlight/audio. I'm thinking to pick up Racketboy's VGA cable with the S-video port to test them both out to see what it looks like. Even if the S-video is still flakey, I will be able to use the better VGA plug to the television. Of course, just in case it's the 'cheap cable' problem, I'll buy the more expensive Nintendo cable to test that theory to be sure.

Anyone else have this problem?
