Protron 37" HDMI not producing sound

I just hooked up my new HDTV to a DVR box using the HDMI cable and I don't get any sound. My understanding was that HDMI was video and sound. Any ideas? Thanks, Peter

Re: Protron 37" HDMI not producing sound

Not sure what model you have , but the original Protron 37", the hook up is a DVI and only a computer can be hooked up to this.

There is no HDMI on the original version of the Protron 37". A later version does have the HDMI hook up.

Check the volume control on the DVR box. This is sometimes turned down. Good Luck

Most likelly it is your DVR that has a problem. Their are a lot of issues with those DVR's from the cable or satellite companies. I would recomend swapping it out.

I have a 55" LG

Easy solution; this is a very common problem. Connect Cable or satellite box / DVR directly to one of the TV HDMI inputs. Connect an optical audio cable from that box to receiver so sound is surround through your speakers. You cannot connect DVR directly to receiver because the anti pirating chip will shut off the picture and produce a green or no screen at all.
You can, however, connect a BD (Blu-Ray) player via HDMI cable directly to your receiver without that problem. Connect HDMI output from receiver to a second HDMI input on the LG.
Contact me if you need more help! All the best, John

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

Hope this is useful.

Connecting HD cable box to DVR too HDTV

When I hooked up my HD cable box using an HDMI cable, I had to go into the cable screen menus and select HDMI output. You may have to do something similar when using an S-video cable. Your DVD recorder doesn't seem to have an HDMI input, so you'll have to use the S-video or (worst case) composite video (red, white, yellow cords). Your cable box may also be scrambling the signal so that you can't record. That may be why you can record by bypassing the cable box.

Hdmi and audio

It may be the top of set box.. Most times the sound and picture are auto detected by the set when HDMI is used. Both sound and video are carried in a HDMI cable but not with a S video cable. Try another HDMI cable *** dont buy the expensive one the tv don't care if they cost $125 or $25.

Connection problem

The best hook up for this unit is to use the hdmi if your samsung box offers hdmi output. The panasonic vcr should be hooked to any one of the composit video inputs with the yellow video cable and the red and white audio cables. If the vcr does not have composite output then use a rf (coax cable) to antenna a input and put the tv on channel 3 or 4 as vcr is set for.
