Question about Norcent Technologies LT-2022 20 in. EDTV-Ready LCD Television

1 Answer

I have no sound on channel 2. All other channels the sound works fine. There are no audio cables going to it. Just straight cable. Even moved it to another room to see it would make a difference. And it does the same thing.

Hello mwrobinson19,

Check to see if SAP (Second Audio Program) is turned on. Having SAP on can often cause this problem. You will have to go to the audio settings from the menu and select to turn SAP off.

I hope this helps,

Thank you,

Do you have a digital converter box. If not, you need to get one to receive the analog channels.

My Sharp Flat Panel Television LC19SB25U has Picture but No Audio


Sharp has had a few problems with their audio boards, not finding any bulletins on this model, but a few complaining about low audio on amazon reviews section. If using an antenna you will experience some channels with low audio. If using cable you should get good sound on all channels..
the 9.1 and 9.2 are digital channels and sharp does display them for at least a few seconds when you switch to that channel. Check all your setting in the audio to Stereo never SAP. To options for you are get a cable box, first check in the back and see if there is another coax in, if there are two try both rescanning after connecting.

Cable company switched to digital and the audio quit working for channels under 100 - former analog channels. channels 100+ work fine. when I switch to dtv, I get the "no signal" message.


If you are using HDMI with the cable companies cable box, you may have to go into the
cable box menue and set the audio out as HDMI. I had a similar problem with my cable providers box.
Hope this helps,

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.

No sound on just one channel


Do you have another TV in house that works with this channel correctly? Do you have a VCR (or VCR/DVD combo) that you can use to tune to this channel? I'm wondering if your tuner is going bad on this one channel. Do you have SAP (Second Audio Program) turned on? You may want to turn it on and then check channel for sound. I'm assuming that you're getting your cable feed thru coax and not composite (red & white audio). If you are using composite, try switching the red & white inputs to see if sound comes in. It's possible that cable company is only outputting audio on left or right channel and something is wrong either with one of your TV's speakers or with the cable company's output.
