If I remember correctly, you have to turn off the set's speakers in order for the optical audio out to function.

Lip sync


Vizio HDTV- Lips out of sync

Anyone with a new Vizio E601i-A3 60" or 70" HDTV that is having audio "Lips out of sync problems" with a cable or satellite box.

On Comcast cable boxes (or others), here's what you need to do: FIND MENU for AUDIO or HDMI setup on CABLE BOX or Satellite Box.

FOR COMCAST

1. Turn on TV and have Cable box Turned OFF.

2. Press MENU on COMCAST REMOTE.

3. Go to AUDIO Setting OR HDMI Setting. (On cable or Sat. BOX)

4. Change setting from Auto to L-PCM. (Turn off cable box to exit)

This should resolve any "out of sync" lips to picture after commercials on HD channels.

*This is a handshaking issue from the cable box to the Vizio E601i-A3

How do you get the picture in picture to work? What two sources can you use, a cable box and what?


The Picture in Picture (PIP) on VIZIO televisions works on multiple input sources. This means you have to have signal or a device connected to more than one input on the television and have both inputs selected to display the information going to them. Here is an example. Let's say you have an HD cable box connected to your television and you would like to have more than one channel displayed on the screen in order to keep an eye on both football games at the same time. With one device connected that's not going to work out the way our TV functions. What you want to do is get a coaxial splitter and two extra coaxial cables; these can be found anywhere home theater equipment is sold. Then follow these steps.

1. Turn off both your cable box and television.

2. Take the coaxial cable that comes OUT from the wall and connects to the IN of your cable box and disconnect it.

3. Connect that cable to the IN on your coaxial splitter.

4. Connect your two extra coaxial cables to the OUTs on your coaxial splitter. We will call them cable 1 and Cable 2, just because.

5. Connect cable 1 directly to the DTV/TV input on your television.

6. Connect Cable 2 directly to the IN on your cable box, this will be the same connection you removed it from in step #2. Your HD cable box should still be connected to your television with either an HDMI cable or Component cables (Identified by their Green, Red, Blue colors for video and Red and White cables for audio.)

7. Power on both the cable box and your television. Using the INPUT button on your VIZIO remote select the input connection where your cable box is located your cable box picture should come up on the Main screen.

8. Press the PIP button on your VIZIO remote to bring up the small box in the corner. Press the PIP input button until you select the TV input and you should be ready to go. You may need to perform a channel scan with your TV tuner to locate all available channels before you do this step. In order to understand better how to perform a channel scan please check under the F.A.Q.s in the discussion area of your particular model television.

In order to change channels in the small screen use the PIP CH - and + buttons located near the bottom of the remote. You can swap picture in the Main and Sub screens using the swap button and swap which screen will sound off its audio by using the AUDIO button. You might notice an X next to some of the selections in the INPUT and PIP INPUT screens when you have PIP activated. That means that input selection is unavailable and cannot be used. For example, if you have the input TV selected on your main screen then if you press the PIP INPUT button and bring up that input menu you will see X's next to the TV and AV selections. The X's mean that when you have TV on the main screen you won't be able to use TV or AV on the small screen. Instead you would need to use any of the input selections that do not have an X attached to them.

How to connect a vizio lcd hdtv to my 1976 kenwood KVA 503. My Vizio has no speaker outputs except a digital optical audio. I had it hooked up before and then moved and now I can't get it back...


Obviously the digital optical connector was never connected to the vintage Kenwood.

It sounds like your Vizio is NOT the actual root SOURCE of the TV audio but it's coming from a Cable Box which DOES have various audio outputs. Connect it as you would any other analog audio source (except don't use the PHONO input).

While most HDMI sources work with good audio and video, we have a compatibility issue with audio from a few specific products (eg, DirecTV HD DVR satellite set-top box, DISH Networks satellite set-top-box, and TiVo Premiere XL cable set-top-box). If you are experiencing problems with no audio or muted audio with one of your HDMI sources, then please try changing the audio settings on your problematic HDMI source to PCM or LPCM. Then turn off the TV, remote power from the WirelessHD adapters, and power off the HDMI source. Now power everything back on. If you are still experiencing no audio then please write down the model number of your HDMI source with no audio and contact VIZIO customer support.

Not sure what this means: "The audio comes to the Cable box through coax cable." From where does audio come TO the cable box? The cable box is a source of both audio and video. Perhaps you mean the TV broadcast "containing the audio and video" comes in on coax.

Has this ever worked correctly? <<<<<<<<<<<<<<<<<<<<<<<<

Try this: disconnect the HDMI that goes from the cable box to the Video 2 on the receiver. Leave the optical audio cable in. How's the audio now?

Then try the reverse: reconnect the HDMI and disconnect the optical audio. You shouldn't need BOTH for audio into the receiver.

Now what happens?

Hook up computer to tv


The Vizio GV47LF HDTV's connection bay has everything we'd expect. It includes a pair of HDMI inputs which can take 1080p sources (at 60 but not 24Hz), two component-video inputs, one A/V input with composite video and one with composite and S-Video, one RF input for cable for antenna connections, an optical digital audio output, and a VGA-style PC input for PC connections.
If you're connecting a computer, you'll probably be disappointed that the VGA input maxes out at 1,360x768 resolution (which did look pretty good) instead of the full 1,920x1,080. We did connect a PC via HDMI and got 1,920x1,080 resolution, but the image didn't look as sharp as the 1,360x768 version. Again, we believe this has to do with the lack of a dot-by-dot mode, although perhaps people playing with picture settings, either in the Vizio or in the video card's drivers, can achieve a better-looking higher-resolution computer image. All-in-all, shoppers looking for a big computer monitor would be better served by the Westinghouse LVM-47w1.

Connect home theatre to 32" lcd to ps3


Depending on the year of your model of VIZIO your digital optical output may be tied to the DTV input only. Meaning the only time you will have audio coming out of the digital optical output is when your using the tuner and your on a digital channel. If your television is newer and the digital optical output is in white on the back of the television than it is tied to HDMI and the DTV Tuner and you will pass audio through the digital optical output when using HDMI or the Digital Tuner.

Now to get connect the HT: Normally you would run a digital optical cable from the source device to the home theatre system. Meaning if it was a PS3 you would run a optical cable from the Digital Out on the back of the PS3 to the Digital In on the Home Theatre receiver. If it was a DVD player than you would run the optical cable from the DVD player to the HT receiver. If you have a newer VIZIO and the optical output is in white and not black than you can run HDMI from the PS3 to the VIZIO and then run a optical cable from the VIZIO to the Home theater receiver.

You will have to adjust the audio setting in the PS3 to run audio out of the HDMI port if it is set to run audio out of the Digital Out or AV out. Also, if your going to run audio from the PS3 to the HT receiver through the Digital Out then you need to change the audio setting in the PS3 to Digital Out.

1. Select (Sound Settings) under (Settings) in the home menu.
2. Select [Audio Output Settings].
3. Select the input connector on the audio device.

Channel numbers and audio formats that are supported vary depending on the connector in use. AV is 2 ch. only, Digital Out is 2 ch. & 5.1 ch, and HDMI is upto 7.1.
