Default Composite cables, No signal problem

This is probably a very stupid question, but I am at my wits end. What am I doing wrong?? I am new to all HD/LCD TV stuff and need to learn, but in the meantime can someone help?

I bought a Vizio 32" LCD/HD tv. I am trying to hook up my Wii and an inexpensive Magnavox home theater system. The wii has composite yellow-white-red connections and so uses the only composite tv connection. Therefore, I bought the only composite cables in stock at the local MicroCenter today, Matix platinum video (3 RCA plugs to 3 RCA plugs component video lead). I plug them into the dvd/hpme theater component out and plug into the component TV connections, but all I get is a "no signal" message on the screen.

I called Magnavox, they say I have it hooked up properly to their unit. Vizio was less than helpful, and confused me about optical cables and output from the TV (??!!!).

Do I have the wrong cables? Can anyone help?

You plugged the Wii into an "OUT" jack, not an "IN" jack. Always remember that a signal comes OUT of a device and must go IN to the TV.

I'd hook the Wii directly to the TV and plug the TV into the home theater with the optical cable as suggested by Vizio. Also, if the home theater has an HDMI or component "OUT" jack, plug those into the TV. (This assumes that the home theater has a DVD player, if not, there will be no need to plug the home theater into the TV.)

Thanks for replying!

I have hooked the Wii up with the yellow-red-white composite cables to the tv in the AV ports. It works.

I have component out on the home theater. I plugged in the RCA component cables, green-blue-red, into the component 1 ports of the tv. No signal. I do not have the yellow-white audio cable yet to hook up the audio, but shouldn't the video work anyway without sound?

What is the optical cable? I didn't understand how it worked or how to connect it. I am not sure there is an optical port on the home theater (I am at work and have to check when I get home). Is that better than the component cable? Will it carry video AND audio?

Thanks again.

Your best pic quality will be achieved if you plug your video cables, Yellow, S-video, Component (red/green/blue) or HDMI, directly into your tv video inputs.

AND....

Your best sound quality will be achieved if you plug your audio cables directly into your receiver, red/white, optical or digital coax (these last two are equal and good).

Your tv's optical output plug will pass only stereo to your sound system. So if your sound system is surround, you do not want to send any sound out of the tv as I mentioned above. You want your sound cables directly into the receiver.

I have listed the cables in worst to best order. If you have any of the "bests" available out of your items, use them, and only use the lesser ones if none of the better are available.

Thanks for that. I see the options. So, I have the green-blue-red plugged into my home theater component out into the component 1 green-blue-red ports in the back of the tv, but it still says no signal.

What could be wrong?

Ripley. Take the component (red/green/blue) cables from your Wii and plug them DIRECTLY into your tv, Component 1 input, not the receiver. Then take either an optical cable or digital coax, if available, plug it into your Wii then plug the other end DIRECTLY into your receiver. Be sure to select component 1 from the tv input/source selector on it's remote and select the optical or dig. coax input from your receiver's remote and it will work and be the best arrangement with your items.

Without the model of your home theater component, I am just guessing here, but I think the lack of video from the component outputs is because the box doesn't upconvert anything. I'll bet you have composite and component outputs from the box - you'll have to hook both sets to your TV in order to see video from the composite inputs and video from the component inputs.

Thanks kegobeer (great name btw)

Plug in both types of cables? The home theater is inexpensive Magnavox (MRD310). Both cables would take up the single AV ports on the tv and one of two component ports on the tv. Would the video actually be better in that case than just using the composite AV cables?

Clearday, the wii only has a hookup for the included cables in the wii box. A pin port on the wii and composite yellow-red-white on the other end to hook into the tv.

Why is this so difficult? Is it because my home theater is low end?

According to the specs for your system, you don't have any component video inputs. In order to see any non-DVD video, you'll have to run a composite cable from the Wii to the composite input on the receiver, and run a composite cable from the receiver output to the TV, or just run the composite cable directly to the composite input on the TV.

Here's what I recommend: buy a Wii component video cable (go to monoprice.com and look around - that's where I bought mine), and run the R/G/B cables to the TV and the audio to the receiver.

That sounds like a doable, and logical, plan. Thanks so much for the help. I will buy my wii cable today and be done with this soon! Transitioning to better technology and trying to mesh my low-end or old tech components is very difficult. Still, I love the new tv!

You guys are great. Thanks again.
