I recently purchased a new Vizio 55" LED 1080p tv but I'm having trouble connection my Nintendo 64 to it. The red & white audio cable are working fine and I'm getting all of the audio but there is not yellow port on my new tv for the N64's yellow wire. The tv does have a green and blue port and when I connect the N64's yellow wire into the tv's green port the images shows up but it's black and white and scrolling upward. On my last tv this red, white, & yellow N64 wires into red, white, green tv ports worked fine, it was also a 1080p just not LED. Any ideas? I thought I might try this device out as a solution. Does anyone know if it would work? ->

The black‑and‑white, upward scroll is what you see when the TV is treating your yellow plug as the Y (luma) line of a component signal instead of decoding composite. On the E55‑D0, the single Component input also accepts composite video on the green Y jack; you need the TV to use its AV/composite decoder, not Component. That hybrid design is documented for this model line. (consumerreports.org, displayspecifications.com)

Practical steps to try:

  • With the N64 powered on, plug yellow into the green Y jack and red/white into the matching L/R audio jacks grouped with Component/AV.
  • Press Input on the Vizio remote and choose the AV (or Composite) input, not Component. If you only see Component, leave only the green jack connected (nothing in the blue/red Pb/Pr jacks) and power‑cycle the TV while the N64 is running; some Vizio sets then auto‑detect composite on that port.
  • Still monochrome or rolling? That usually means the TV is not locking to the N64’s 240p timing over composite, which some flat panels mishandle.

If your set will not lock, avoid the cheap yellow‑to‑HDMI boxes; many do not handle 240p correctly. Use a line‑doubler made for retro consoles. A RetroTINK 2X Pro accepts composite and outputs 480p HDMI with effectively zero added lag, and the 2X Mini includes an N64 S‑Video cable for cleaner video from an unmodded NTSC N64. Either will give you a stable, full‑color image on HDMI. (retrotink.com)

was spot‑on about needing the composite mode; the trick on this set is selecting the AV input so the green jack is treated as composite rather than component.

Connect to the port that has the b/w image then somewhere in the TV menus there's a component/composite setting. You want composite, it is currently set to component.

I contacted Vizio and they said that there is not setting to switch back and forth between component and composite. They said that the ports were interchangeable between component and composite wires and everything should work fine. So I guess I'm SOL. I tried a red, white, yellow to hdmi but that didn't work either. :(
Thanks for your help.

One more question, why does my thread have a 'sponsored' logo beside it?

That's not a nice link. I do read that the composite input is shared with the component inputs but this manual omitted how to change the input from component to composite.

"Need help installing the TV? Refer to the printed Quick Start Guide"

Maybe the composite input and setting is in the other manual? It should be the same as connecting a DVD player.
