Vizio Sound Problem

Have you seen the user guide?

The TV is intended to be an end point of the video, not a source of audio. Many TV's (monitors) don't have ANY audio, much less surround sound capability. Composite Video is theminimalist video connection for setup; Component video to the TV should suffice for viewing DVD's.

Is your TV the SOURCE of surround sound programming (via an antenna) or does the programming come from elsewhere like a Cable Box? THAT would be the source you need to tap for surround sound.

I dont wish to assume that when you say receiver, you mean sattelite or cable. Since you may be trying to hook this up to a surround sound reciever...

Let me also clarify, if this is the case, the receiver needs to be turned on AND the selection signal device set to TV or AUX wherever it is you've connected the TV.

Now by receiver, if you actually meant cable or sat box, then the Ext antena from that service connects to that units ANT IN.

Then from there on that unit ANT OUT to your TV SIGNAL IN.

If you want the external surround sound and have the connectors for this. Then you need to send them OUT to the Stereo/Surround receiver TV IN.

Now having said that and assuming that your TV does not have the Red and White Audio RCA connectors... Your Sat or Cable box does... You connect those to the surround sound Receiver Audio IN

Hopefully you'll find this useful.

If this has not answered the situation. Please feel free to come back and provide all components your working with. Surround reciever, Sat, cable, DVD, VCR whatever etc. etc... I'd be more than glad to help you through this


Good Luck

Hi.

You need to use audio cables. Connect two red and white audio cables from the output on the HD box to the relative input at the back of TV (nr.4 in picture below). The best way to connect the HD box is by using component cables, that are the red-green and blue trio of cables, plus a white and red audio cables.

Here what you need:

Three plus two:
Component Video Cable
Audio Red / White Cable

or single set of five:
Cables Unlimited - Video / audio cable

Once you have the five cables, connect them to the output at the back of the Direct TV box, and then connect the other end of the cable to either group of connectors 6, or to one of the columns in connector 7. Do connection with box and TV power off. After re-applying power use the source-input selector on remote to select the source from Direct TV box.

Your best option would be to connect all your components requiring video to be hooked directly to tv through HDMI in or component in. With a component hook up, you will have to provide audio with either digtal optical or composite cables. You then would want to provide sound to your surround sound by a digital optical out or composite out to the input of your surround sound.

You could just source the audio from whatever external source you're watching (BD,DVD, Cable, SAT) directly and digitally to the Panasonic. The TV doesn't need to be an active player in the audio chain. Some have NO audio capabilities at all yet we manage. Treat it as the end of the chain, not a link.

1. Connect cable to cable HD DVR box, connect video out of cable box to Sony receiver TV video in, connect audio L and R out of cable box to Sony receiver TV audio in and connect TV out of receiver to video in of Panasonic projector 2. Connect Audio and Video out of DVD player respectively to DVD in of receiver. Good Luck :)

if the Comcast cable box has an HDMI output, it should connect directly to one of the TV HDMI inputs. Then connect the LG DVD unit HDMI output to the second HDMI input of the TV. Use two HDMI cables. Do not buy the expensive Monster HDMI cables. If you have already done so, I recommend you take it back for a refund, then buy the low cost HDMI cables which will work just as good and then you can bank the savings toward a new Porsche Boxter!! Now we have the video connected from both the cable box and the LG system.

Now--what do you do if the cable box does not have an HDMI output--just use its component output and your component cable (red, blue and green) to connect to the TV component input. This will still get the video to the TV and good HD pictures. Hum--do you have an HD cable box? You did not say and I just assumed that you did since you got the HDTV. If not, let me know with a follow up question and I will assist in that area further.

Now for the audio connections--The DVD player will not need any connections since it in the LG unit. The sound will come out the speakers when you start playing the DVD. The cable box is where we get the TV audio to feed the LG unit. If the cable box has an optical output, use an optical cable (again the low cost one)and connect to the optical input on the LG.
This will get the TV audio to the surround system. If no optical output, use the red and white (left/right) audio connections and connect to one of the two the LG audio inputs. To hear TV audio on the LG speakers, just switch to that input or the input associated with the optical input.

To watch DVDs, switch the TV to the HDMI input to which you connected the LG unit. For TV, go to the other HDMI input (or component input).
Switch the LG to the audio input to which you connected the cable box to get TV sound.

Hope this gives you food for thought. If so, and you have more questions, just come back in with a follow up.

For connections of audio, so that you can hear all tv audio through the
surround system, connect either an optical audio cable or red & white
analog audio cables from the tv to the home theater. If you are using
optical audio, there is a plug on back of tv labeled for digital audio
output and an input on the surround sound system. If you plan on using
analog red and white, use the PROG OUT red and white output jacks on the
back of the tv to the AUX input on the home theater.

For video connections, to get HD you will need to be using either HDMI or
Component cables. HDMI is the cable that will provided 1080p signal (the
best HD signal), but if the source does not output 1080p, then your tv
will not display 1080p. Most cable boxes output at 1080i or 720p when on
HD stations. This signal still provides great picture quality, but HDMI is
not needed to get these HD signals. You can use component cables for your
cable box and the DVD player output to the tv for video. HDMI might give
you a slightly better picture quality but the signal will be the same.

To make the connection, you will want to connect from the cable box to the
tv (component or hdmi). Also from the home theater system to the tv using
hdmi or the video cables from component (red, blue, & green cables).

We hope this information is helpful to you.

Thank You,

I had the same problem. I could get an analog audio signal but no digitial signal. My problem was with the cable box setting. I have Cox Cable. With the Cable remote I went to settings/settings/Audio out and selected HDMI. Worked like a charm

In short, the answer is: Hook up all three to each other. I have a Samsung DLP HDTV, and I was trying to hook up a Sony DAV-HDX500 home-theater system and a Comcast HD set-top box, but I found that the Sony user guide is helpful only for setting up the speakers. Most of what it had to say about HDMI and getting the TV sound or cable sound to go through the speaker system was wrong (or, at least, it didn't work for me). So, here's what I did. I connected Component video cables (Y/Pb/Pr out) from the Cable box to the TV (Y/Pb/Pr in), audio cables from the Cable box (audio out) to the Sony system ("SAT/Cable" audio in), and an HDMI cable from the Sony system (HDMI out) to the TV (HDMI in). This allows me to 1) watch DVDs with surround sound through the TV's HDMI source (when the "DVD" format is selected on the Sony system), 2) watch cable with surround sound through the TV's Component source (when the "SAT/Cable" format is selected on the Sony system), and 3) watch cable WITHOUT the surround sound, as I did before I ever had the Sony system. One item of note: When watching a non-HD channel with the surrond sound on, the audio is slightly out of synch with the video; thankfully, there's no such problem on HD channels. Anyway, I hope this helps. It drove me crazy for two days straight!
