HDMI DOES NOT WORK ON MY DYNEX 37" HDTV FLATSCREEN

MY DYNEX 37" HDTV HAS A OUTLET FOR HDMI. I PURCHASED THE CORRECT HDMI CABLE AND IT WORKED BEAUTIFULLY FOR THE FIRST DAY. HOWEVER, THE NEXT DAY I WENT TO WATCH TV AND MY TV COULD NOT FIND A SIGNAL. I EXCHANGED CABLE BOXES AND EVEN PAID FOR THE CABLE COMPANY TO COME OUT AND TRY TO REPAIR PROBLEM TO NO AVAIL. I HAVE TRIED A NEW HDMI CABLE AND IT STILL WILL NOT WORK. THE ONLY WAY TO GET A HD PICTURE IS TO USE THE COMPONENT OUTLETS. THE PICTURE IS GOOD BUT NOT AS GOOD AS WITH THE HDMI OPTION. I AM HOPING YOU CAN SOLVE THIS PROBLEM. THANK YOU, PACKY PAULES

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

You will have to go into the settings of the hd box by pressing the settings button twice and then scroll down to "audio digital out". chances are that it is set to Dolby Digital. If you right arrow over you can then set it to HDMI. this should bring your volume back. Hope this helps.

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.

SOURCE: Vizio L32 32 in. HDTV LCD HDMI input not working

I recently had the same problem with my vizeo hdmi port # 1 going bad. Tried everything to fix and called vizeo. There solution for a master reset was turn off tv and unplug from the wall. then hold down the power button for 30 secs and let go. plug the tv back in and hold down the volume down and input select buttons down on side of the tv for 15 secs. release the buttons and turn the tv on after powering down all the components connectd to the tv. If this does not work they told me you need to have it sericed for a bad hdmi input. Hope this info helps anyone out there. It didn't work for me. Its a bummer cause the tv is well taken care of and only 18 months old. Best of luck to all others.

There is a hidden menu. Press the "MENU" key and then press "991". You now see a new menu labeled "Factory". One of the settings is: EEPROM Init. Selecting this supposedly resets your television and erases almost everything you've set... so don't do this casually. And don't press anything until it is done. I'm actually afraid to try this since my set works. If this fries your set, you're on your own.

Tv sound doesn,t work from remote ,but works on tv


Are you using an HDMI cable from your cable box to the TV? I found that the sound greatly improved and volume control was better after switched to an HDMI cable. Originally I was using component cables that were supplied by the cable company. Note: I bought my HDMI cable on line for $10. I've seen the same cable in the store for $35.
