No audio on pasma when cable set box set to certain channel

I lose audio on certain channel when selected and lose audio after that point on all channels until I turn off cable set box and tv. I have had the cable box replaced and connected another HDD on the cable set box which will work fine.

    When I connect a coax cable from the set box to the coax cable input of the plasma audio does work. So it is definitely with the HDMI/DVI connection. I have tried both HDMI/DVI inputs on the set with the same results. All channels work fine from the set box except for one channel.

    Have you tried to do cable direct i.e, connect cable wire directly to your tv set, to determine if problem is from your tv or from cable company? You might want to check whether your tv is on what we call SAP. You can find out this by going into menu opf your tv and select audio. If is in SAP you want to change it to Stereo

In that case two things might be happening. 1. HDMI/DVI cable you using might be faulty you want to change that or 2. The HDMI input of your TV set might be the problem. I will suggest you use component cable instead, I am talking about the 5-color-coded (green, blue, red and red/wihte) cable to connect the set top box to your TV.

How do I set the TV up for satellite TV


The TV will likely require a Satellite TV converter box. The output of the box should be mated to the best matching input of your TV.

That order would be: 1) HDMI, 2) Component (RGB) + Stereo Audio, 3) S-Video 4) Stereo Audio, 5) Composite (Yellow) and Stereo Audio 6) RF (Coaxial).

When selecting 6) RF (Coaxial), you would normally select an output channel on the Sat Box (Ch3 or Ch4) and set the TV tuner to the same channel. A standard coax cable would be installed between the Sat box connected and the TV Ant connector.

All other TV inputs would match the one you used (HDMI, Componet, etc.

I am trying to hook up my cable box so i can watch tv.


At the cable box input, connect the cable (probably labeled "Cable In" or "Signal In").

Depending on the cable box model and available inputs on your TV, connect one of the following (listed in descending order of video quality). Colored phono plugs must match the colors of the plugs on each end.:

  • HDMI (a single rectangular connector at each end - sometimes you need to connect the Audio separately with a two - line cable with red and white phono plugs).
  • YPbBr, AKA Component (Cable with Red, Blue and Green phono plugs, plus a separate Red and White cable set for Audio).
  • S-video (a single round connector and separate Red and White audio cables).
  • Composite (Yellow video cable plus Red and White audio cables, usually sold as a single set).
  • RF out on the cable box connects to ANT or Cable In on the TV with a coax cable.
The various options are always grouped in some manner on both the Cable box and the TV. On the TV, note which input set you use, for example, "Component 1". This is the input you will select to watch whatever channel you select on the cable box.

An unused output on the cable box can go to a video recorder. Some cable boxes may permit setting up two different channels for this purpose; others will only put out the signal from one channel at a time on all outputs.

You may, if you prefer, connect the audio cable from the cable box to a stereo receiver instead of the TV. Usually people connect the audio to the TV, then connect another audio cable from "Audio Out" or "Monitor Out" on the TV to the stereo receiver. That way the sound is from whatever video source is currently selected, and the TV remote control can be used to set the volume. TV sets with this option usually have a setting to turn off the internal speakers so you hear only the external stereo speakers.

I have a VIZIO LED/LCD VF551XVT hooked up to a motorola HD DVR with a HDMI cable. When I switch from standard Def to High Def channels I lose the sound. If I turn the TV off/on the sound returns but if I...


I have the same set, same problem with one of my MOTOROLA boxes, but not with another. I have a SONY TV that works fine with this new MOTO box, but the new VIZIO does not. The audio is coming through the HDMI cable just fine, and the fact that it works when you cycle power on your TV means it's the SYNC between the TV and the BOX. I have the identical problem and am taking back the MOTO box for another one. I spoke to VIZIO for about 45 minutes trying different things. They think it's the MOTOROLA box, COX (my cable company) thinks it's this particular box, who knows.

Low volume on LG HDTV


I encountered the same thing using the HDMI interface on my new TWC cable box (Motorola DCX-3200). After a little bit of research, I finally fixed it by changing the digital audio mode in the cable box using this procedure:

1. Be sure the TV is on and connected to the cable box.
2. Using the cable box remote turn power OFF.
3. Immediately press the MENU key on the remote. The USER SETTINGS menu should appear on the TV screen.
4. Select the ADDITIONAL HDMI SETTINGS >>> menu item.
5. The ADDITIONAL HDMI SETTINGS menu will appear.
6. Scroll to the AUDIO OUTPUT item and select this.
7. Change the setting from AUTO to L-PCM.
8. Return to the main page
9. Using the remote, cycle power OFF.
10. When the cable box is turned on again, you should be good to go.

I realize these instructions are specific to the DCX-3200, but there may be a similar setup option available in your cable box as well.

The problem here is that the cable box is by default configured to use Dolby Digital audio, which requires an additional 10dB of headroom to deal with the boosted LFE channel. If the cable operator hasn't taken pains to set the system up correctly (and most haven't, apparently), the digital audio level sent on the HDMI interface will be approximately 11dB down from normal analog line levels on the HDTV channels. Changing to straight linear PCM sets the TV receiver audio level on the HDTV channels to match the levels on the non-HD channels.

The only problem with this fix is that if you intend to feed a Home Theater receiver that uses Dolby Digital processing with the cable box output you will lose the Dolby encoding feature and be forced into straight 2-channel stereo. For a simple installation like mine where I'm just feeding the TV, this fix works fine. If you have a more complex setup that takes advantage of Dolby Digital features (when it's available in program material), you may have to live with the problem.

For a technical reference on why this happens, see http://www.megahz.com/specimages/Dolby/LM100%20Cable%20App%20Note%2011-05.pdf

Hope this is useful.
