Dynex DX-LCD37 Audio with HDMI

I've connected this TV from HD DVR box with HDMI and get no audio. I've added the RCA plug component audio with the HDMI hookup and still no audio. If I use S Cable and RCA component it works. Any suggestions with just the HDMI Cable because I hope for the best pic and sound I can get.

    Something I did not mention. I'm using a HDMI switch box because I also have a BluRay running to the TV. The BluRay runs to the switch box which runs to the TV and no problem with the audio from the BluRay. The TV is connected just like the BluRay and I've changed their plug positions in the switch box with no changes.

    I should have said the TV Cable DVR is connected just like the BluRay...

  • Gary W Jun 06, 2008

    Before the BluRay the DVR ran to the TV with the HDMI and no problems. As I said I've switched the cables plug position on the box and the BluRay has audio, the DVR / TV does not. And I've used three different HDMI Cables in all configurations.

  • Gary W Jun 06, 2008

    All Cables have worked plugged into the TV... The TV Connector has and still works. Picture and Sound are perfect from the BluRay into the switch box into the TV from either switch box plug connection... The picture from the DVR into the switch box into the TV is perfect, but no sound at all from both switch box plug connections. What am I missing?

  • Gary W Jun 10, 2008

    Is there any one of the "paid for experts" besides "IrishDruid" that might offer a suggestion besides "probably Faulty?" If you read my posts you'll see with different configurations all works, I'm just trying to figure out the correct configuration to get all to work at the same time...

    If that works, then there is an issue with the box. If it still doesnt work, try replacing the HDMI cable.

    If the replacement HDMI cable also doesnt work, then the issue is either with the HDMI connector on the TV, or some loose wiring to the HDMI socket on the TV.

    The audio component on the HDMI for the DVR is probably faulty.

    Hi garpsych,
    Unfortunately, thats the limitation of this this forum, in that we cannot actually physically do anything, except try to diagnose the problem and offer troubleshooting tips.

    It does look as if the audio component of the HDMI on the DVR is faulty, as the switch box and blu-ray seem to work perfectly.

    Also, the DVR works with other connections except with the HDMI..

Check tv setting for audio. If off turn on.

If you use a sound system make sure it is on and connected to your TV using hdmi from sound system to cabl box.You must have your remote able to turn on audio and tv at the same time. Be sure your input setting is hdmi 1 if you use cable and tv is plugged into hdmi1.

If you still don't get sound can't act you carrier sorry tv vendor

Depending on what type of connection you are using from the cable companies DVR to your TV and what type of connections you have on your TV you can try the following..
1. As your DVD player supports HDMI, component and composite video out, check to see which spare AV inputs you have on your TV and connect the corresponding free input on your TV to the matching connector on your DVD player. You will also need to hook up audio from the player to this AV input on your TV using the options available on your TV (either RCA phono or optical in).
2. If you have no other AV inputs on your TV then buying an HDMI switcher or a component switcher or a simple an RCA phono y cable for composite video will allow you to connect both your DVR and DVD to the same TV input.
Hope this helps.

I have succesfully connected my dynex 32" lcd hdtv 720p 60hz to my rogers digital box and my xbox but i only have room to connect my audio cables for my surround sound speakers to my tv cables there is no...

What cables are you using for the XBOX and the digital box? What surround sound system are you using (what receiver)? Which model of Dynex 32" TV do you have? Looking at the DX-L32-10A, I can connect both devices to the TV and then the audio out to the surround sound system.

If HDMI, then that will carry the audio to the TV and then you would need an audio cable from the audio out on the TV to the surround sound speakers. Similarly, if you use component video and the audio cable combination, there are 2 component video jacks and 3 audio-in jacks on the rear of the TV. Then connect another cable from the audio out of the TV to the surround sound system. (This TV has one audio out and a headphone jack.)

If you previously had the audio going from the Rogers digital box directly to the surround sound system, you need to reroute things unless there are two or more sets of audio in jacks on the surround sound system. Some surround sound system can take several HDMI in cables and then route it to the TV on a HDMI out port.

Without more information, I can't be sure of the best option for your cables.

I hope this gets you started and please provide more information for additional suggestions.

Do i need to use HDMI wire if i have a cable box ?

It depens on what the cable box outputs are, you need to see if it has RF Coaxial jack (use CH3 or CH 4 on the TV), composite video out (Yellow RCA jack) with red and white RCA for audio, component video outputs (Red, Green, and Blue RCA jacks), or HDMI output jacks. HDMI and component video are for HI-DEF if you subscribe to the HI-def package. The cable company should provide you with the owner manual. Please post back with more info.

Is tv an HD tv

Yes, mostly all new displays are at least 720p which display a great picture ! However, coax cable is the worst possible cable you can use. Your best bet for HD from the cable box is to use component cable. These are the 3 RCA type colored cables, red, green and blue. You will also need another two RCA cables for the audio, which is usually red/black or red/white. If you have a surround sound receiver, then you will not need the 2 for audio to the TV. These 2 would goto the receiver or you can use a better digital coax or optical cable for audio.
Also, HDMI from the cable box to display is a more expensive cable which will give you HD but doesn't always look better then component on some HD cable boxes.

I just bought a Dynex DX-LCD19-09 19 inch TV. I also have a Phillips home theater system. I have digital cable and I cant figure out how to hook it up to where i can watch regular tv but hear it through...

The only audio out jack on your TV is for the headphone on the left side of the TV. You need to purchase a 3.5 mm to RCA audio cable, connect the 3.5mm jack to the left side of your TV and the 2 RCA audio cable ends to the audio in of your Home Theater and then select AUX 1 or AUX 2 on the home theater depending on which jacks you plugged into.
