Optical audio not working

I am trying to get optical audio in from my Samsung 5087 DLP TV. I can see red light coming in from the cable from the tv, when I plug it into the JVC the display recognizes that it is hooked up but no sound comes out. I have it set to Digital input and TV for digital in. Any suggestions? Are the two devices compatible? Thanks!

Connecting Samsung TV to Sherwood Newcastle R 865 Receiver using optic cable.

The problem might lie with the TV itself. The optical input might be switched off. You can check if the signal is coming out of the TV. With the optical lead plugged into the TV and the TV on. But not plugged into the Amp. You should see a red light come out of the unconnected end. If you don't see that the socket is switched off at the TV end. It might come under sound in the menu, or options, or digital audio output. Or a combination leading to the other!
If you see an option for Dolby Digital, set that to on as well. Some HD TV channels use Dolby, but others don't. It will only come on with certain films and TV shows though, it should switch your receiver to the Dolby setting, just like DVD and Blue Ray discs do.

How do you hook your receiver to your TV and make surround sound come out?

There are many configurations available for making these connections. They are specific to the TV and receiver.

The most common is an optical connection from the TV to an optical input available on most receivers.

If a cable box is being used I would make the connection from the cable box using the optical output directly into the optical input of the receiver bi passing the TV. If you are connected via an antenna then you would connect the optical to the TV.

The red and white RCA connectors are not surround sound and will only produce sterio.

Hope this helps?

For audio from my samsung led tv to my samsung av receiver must i use an optical cable connection?

There should be setting menu on tv whereby you can select RCA or units have automatic selectivity when you use optical cables so they will gives instant output when switched on....make sure you pull off the plastic ends covers ,they only go in one way into the connection ports.if you only have RCA leads you may have to set up the output audio on tv menu.

Sound from my plasma TV does not work on AVR 235 via optical cable

So much can go wrong. WARNING!! NEVER LOOK STRAIGHT INTO THE LIGHT FROM AN OPTICAL AUDIO OR VIDEO SYSTEM. The optical output could be not working (try switching it on and look if you see a red light) The optical cable can be broken inside) see if the brightness of the red light is almost the same as what is coming out of the TV. Point it to a white paper to view.
The optical input from your receiver can be defect or dirty. The optical protocol can be wrong or the systems are not compatible.
If it ever worked, the most chance is the cable is defect.
Otherwise follow the chain and read what the manuals have to say about how and what.

How do I connect Samsung smart TV to a Yamaha receiver and get sound to come out of surround sound speakers?

Generally you will connect the Digital audio or optical audio cable from TV to the input of Receiver. Then using the remote control of Receiver you will program the source for digital audio or optical audio as TV. I am assuming the speakers on the receiver are already connected and working. All you do is then turn on TV and turn on Receiver and select TV on Receiver. The TV audio will play through the receiver. Make sure the TV sound is in Mute.

Digital optical output for technics 5.1 surround sound receiver

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.

Does the pioneer sx315 receiver work with the samsung led?

From memory, this amp does not have HDMI.
If this is the case, use an optical fibre cable for your connections.(Audio)
And if you want every thing to run through your amp you will also need to use component video cables (red/green/blue)
I would suggest the following.
Blue Ray to TV with HDMI.
HD Reciever to TV with HDMI.
TV AUDIO OUT to AMP with Optical Fibre.
This way, whatever is displayed on the tv, the sound will come throught the amp.
Hope this helps.

We have a cable box, rca reciever, a dvd and a non digital tv. Does the reciever need input from cable box, dvd and tv?? is red, yellow and white audio/video enough to connect or is a S-cable or optical...

From your cable box, send "optical" to the receiver. From the DVD send "coaxial digital" (looks like one rca cable" if your receiver has it, if not, optical is fine as well. There is no reason to send audio from the TV to the receiver unless you are using an "off-air antenna". If you want to have audio from the cable box to the TV for listening to TV speakers only, send an audio video cable (red/white/yellow) direct to TV. If you need more help just post a comment and I can help you some more.

8' Optical Cable from TV to Receiver and Signal is Breaking Up

Before you buy anything try checking the AUDIO Settings in the Menu of Each Device (Mostly TV) and see if they are set to PCM or BITSTREAM. HDMI is mostly set to PCM while Optical is generally Bitstream. The TV may be set to the opposite of what it needs to be. I would try to get PCM to work first cause it is Better, If not then set what you can to Bitstream and it should pass. Also check in TV Menu for SOUND OUT or AUDIO OUT or SPEAKERS. Some TV's have a problem passing Audio through when they are already Outputting them to it's own Speakers! I Hope this Helps out!

Help with AG-D9320

These recievers are prime for running surround sound through you TV. It all depends on your TV service, Now if you have a cable box from Dish network, this is the easiest in the world, all you need to look for is an output labeled "OPTICAL OUT". It's a small port with probably a small glowing red light coming out of it. You'll need to buy and optical cable and plug it in there, and then run the other end to the optical input of your surround sound reciever, and then assign a video input to that digital audio signal. It's the best audio you can get by far.

Now if you down't have that, it is still very easy. Find you reciever look for a video input and plug an audio cable in(Red and White cable). Plug the other end into your TV's audio output, a red and white output that is probably labeled audio out, plug that in, switch TV to whatever you are viewing, turn on the reciever to whichever input you assigned and there you go.

If your TV doesn't have an audio output, then you need to go to your cable or sattleite box, and find the audio output, the R/W(Red & white), and run that out to your reciever, the sound won't come through the tv unless you run a second audio out from the reciever into you tv's audio input on the same signal your picture is coming from.

I hope that helps.
