I bought a Sharp Aquos HDTV. Am trying to use a digital co-ax cable to run tv thru my reciever. I get no sound. there is only 1 place on each device to hook up this cable. Any suggestions?

I dont wish to assume that when you say receiver, you mean sattelite or cable. Since you may be trying to hook this up to a surround sound reciever...

Let me also clarify, if this is the case, the receiver needs to be turned on AND the selection signal device set to TV or AUX wherever it is you've connected the TV.

Now by receiver, if you actually meant cable or sat box, then the Ext antena from that service connects to that units ANT IN.

Then from there on that unit ANT OUT to your TV SIGNAL IN.

If you want the external surround sound and have the connectors for this. Then you need to send them OUT to the Stereo/Surround receiver TV IN.

Now having said that and assuming that your TV does not have the Red and White Audio RCA connectors... Your Sat or Cable box does... You connect those to the surround sound Receiver Audio IN

Hopefully you'll find this useful.

If this has not answered the situation. Please feel free to come back and provide all components your working with. Surround reciever, Sat, cable, DVD, VCR whatever etc. etc... I'd be more than glad to help you through this


Good Luck

# 1. You need to connect all your components to your TV via an HDMI cable. For true HD and digital sound this is needed. Your TV (if its an HD TV) should have 3 or 4 HDMI inputs. So your Xbox/PS3 should be connected via HDMI cable. Your HD sat or cable box should also be connected with an HDMI cable. Same for your Blu Ray player.

#2. Now that your components are connect in a way which will enable you to see their media in either 720p, 1080i or 1080p your ready to get the Digital sound to your speakers. On the back of your TV you should (again on most all HD tv's) have a digital audio (optical) out. You need to purchase a digital (optical) audio cable and plug one end into your tv's digital audio out jack. Then plug the other end into your audio receivers digital audio in jack. You may have to go into your receivers menu to select or enable the digital/optical input. Then you should be rocking and rolling with true digital DTS, Pro Logic, Pro Logic 2 in either 5.1 or 7.1...

Think of your TV as the hub. Connect all the components with HDMI cables. And then your TV to your receiver with a digital/optical cable. It's that simple.

Never never use the red and white cables for audio. They were designed for 2 channel stereo sound. They won't deliver 5.1 or 7.1 digital sound.

Also... Don't ever hook up any component using the old "yellow" video cable if you want picture quality better than 480i resolution. They won't do HD period.

Here is a list of the popular video cables and they highest resolution.

Yellow video cables - 480i resolution

S video (super video) cable - 480p

Component video cables (red/blue/green) - up to 720p

HIgh definition multimedia interface HDMI - up to 1080p (full HD) and digital sound.

Hope this helps...

Digital optical is one of the best but, it will only transfer sound, not video. Digital coax is the same. The best thing you can do, make and model numbers on your components would help, run all your inputs through TV if you can, either by HDMI, or component cables. Componenet cables don't do sound either but, you could use RCA for sound. If you feed to TV first, then feed audio to reciever, it should work. You will only have one audio output on reciever and can select your output through TV.
