Connect Nintendo 64 to a modern flat-screen TV?

Coincidentally, I also have a 55" Vizio TV and a Nintendo 64, my favorite console of them all, in my room. For whatever reason, I was able to get my GameCube to work with the TV, but I never could get the N64 to. I just tried it again, and went through every setting I could find on the TV, but still nothing. There's no picture, but I can hear music for not even a second before it goes silent. My Nintendo 64 definitely works, as I was playing Super Smash Bros. on it just a couple of hours ago with a different TV.

All I can tell you is make sure the N64, games, and cords work by testing with another TV and then ensure that the composite cables are connected to the Vizio TV like this:

and the input is set to "Composite". If it still doesn't work, then it's your TV. You can either return it and get another brand, get another TV for your game consoles (like I have), or mod (or pay someone to mod) your N64 to output in HDMI (however, this still isn't guaranteed to fix the problem).

If you have a model for the TV I could look for the manual for it.

My suggestions would be to make sure that the 64 works on another TV first. You should be able to connect your composite cables directly to the TV (Red, White, Yellow), and note that yellow is the cable that carries video.

"Comp" on your TV might refer to computer, like VGA, DVI, or something. Look for composite specifically or A/V

Another solution would be, if the TV doesnt want to take it, to buy a converter between the AV and HDMI format.

If your TV doesnt take it by itself, you propably need something to convert the N64 signal to something readable.

You can actually connect any composite (Red, White, and Yellow) cabled device to component (Green, Blue, and Orange video with Red and White audio) ports simply by plugging the yellow video cable into the green component jack, as RedEagle shows in their picture. Just switch to the input, which will be called Component by default or possibly switch to Composite if the TV recognizes the difference, and you should be good to go. Just make sure that nothing is plugged into the blue and orange jacks, as the TV will try to get a signal from those as well and the picture will be messed up as a result.

This seems to be an issue with some specific Vizio models. My model is a D58u-D3 and I'm guessing similar models will have the same problem.

It has to do with the TV. I have a Vizio D58u-D3 and my N64, SNES don't work, but they work just fine on my Vizio E320-B2. I do notice that on screen where it shows my resolution, the D58 TV, goes blank... where on my E320 TV it shows 480i. My thought is the newer of the Tv's is struggling to manage the frame rate, possibly too low?
