    Well when a receiver says unlock on the front display then it is not receiving an audio signal. So check all audio connections.

My digital tv is saying no singal whats the problem and how do I fix it? we have a huge antenna on our roof

1 – Is the NO SIGNAL issue happening on just one TV?
If it is just one TV that is showing the NO SIGNAL…
-Be sure your TV is on the correct source or input as your CABLE or SAT BOX.
-Press the TV button on TV remote control to turn your TV ON.
-Press the INPUT button on your TV remote control.
-Cycle through all the inputs on your TV.
-Do this until you are on the INPUT your CABLE or SAT BOX is plugged into.
-You should then see the CABLE or SAT programming show on your TV.
HINT: Your TV will most likely list the TV INPUTS as: HDMI 1, HDMI 2, HDMI 3, VGA, Component 1, Component 2, and so on.
If you still see NO SIGNAL on your TV screen, see the next step below…

2 – If you have your TV on the correct INPUT or SOURCE and you still see NO SIGNAL…
-Remove or unplug the power cable from the Cable TV or SAT set top box.
-Keep it unplugged for 2 to 3 minutes.
-Plug the power cable back into your Cable or SAT set top box.
-Give it some time for the Cable or SAT box to power up, get the signal, and initialize.
If you still see NO SIGNAL on your TV screen, see the next step below…

3 – If you have reset the Cable or SAT box and still have the NO SIGNAL…
-Remove the HDMI cable or other cables from your Cable TV or SAT set top box.
-Keep the cable unplugged for 2 to 3 minutes.
-Plug the HDMI cable or other cables back in.
-Give it some time for the Cable or SAT box to get the signal and initialize.
HINT: Make sure all the cables that are connected to your Cable or SAT box and your TV are tight, undamaged, and secured.

4 – If all of your TVs are affected with the NO SIGNAL screen…
-Be sure to check the ones where the CABLE or SAT come into your home.
-Be sure ALL Ethernet and Coax cables are secure.
-Call your CABLE or SAT provider to see if there is an outage.
-Realign your Dish if you have SATELLITE.

I just purchased a Sony flat screen tv and need advice on what wires I need to connect my Denon AVR-3300 to it or to the dish cable box? My remote has these options on the remote to listen in...

Your reciever has three digital optical inputs so, what it comes down to is how many thing do you want to hook up and what input/otput do you have on your TV. Best case scenario would be to hook your cable box directly to your TV Via HDMI out, if you have HD, on your cable box to Sat/cable input on your TV. Next best would be using componenet cables for video and digital optical for audio. Last would be RCA(yellow, white and red, from Cable box to TV input. Then, you would connect your TV to receiver via(best) digital optical, or RCA. You can try to patch the video through the reciever using component or RCA to TV/DBS on receiver then out to TV but. alot of times you will lose the video in the transfer and it uses more cables, thus more margiin for error. You would set your TV menu to cable/sat and your reciever to which ever input you choose.

Is the 42lh3000 TV compatible with the ht805sh home cinema system for getting TV sound through the speakers? i have it set up and works fine with DVD sound but i cant get the TV sound to come through it?

I looked at your two products and I'm not quite sure how you have it hooked up but, your TV has a total of 3 HDMI inputs and, a digital optical out, which means, that all your video componenets, DVD cable/sat, if you have, should be able to be connected directly to your TV. You can use the TV's menu to chosse what you want to watch. The TV also has a digital optical out, which you would connect to the digital optical in of the home theater. You would use one setting(sat, aux, whatever, depending on theater inputs), and when have "TV" selected in your menu, you should have sound through theater. You may have to turn volume down or mute for this to work. If you have any questions, let me know.

I have a LG47" tv

Your DVD audio is sent directly to your receiver - not to you TV. That's why you can hear the audio on your stereo. The TV audio is not being sent anywhere - it is "stuck" in the TV and is amplified and sent to the TV speakers. Since the TV speakers are off, you don't hear anything. In order to listen to the TV audio on the stereo system's speakers, you need to send it to the receiver.

You need to have a pair (left + right signals) of audio cables (assuming you wish to listen to stereo sound) from the TV's Audio Output jacks to a pair of Audio Input jacks on the receiver / amplifier. You can use any unused input - CD, Video, Tape, Sat, etc. If you use Tape or Sat audio inputs, when you wish to listen to the TV audio, you must select the Tape or Sat input on the receiver.

Do not send more than one signal to a set of inputs on the receiver. Typically, a CD, DVD and Sat inputs offer two or more of the following types 1) Analog audio. These are the older RCA jacks that have been around since the beginning and require separate cables for left and right channels. 2) Optical inputs. This is the newer digital interface that provides for Dolby Digital (and others) format sound over a single fiber optic cable. 3) Coaxial inputs. This jacks looks like an RCA jack, but usually has an Orange ring - instead of the Red & White rings that analog RCA jacks have. They use a single coaxial cable. 4) HDMI input. This jacks carries both digital video and digital audio signals. If you are using an Optical input for the DVD on the receiver, do not use any other unused analog or digital inputs associated with the DVD to "piggyback" another device like a CD , VHS tape, etc.

I hope this helps and good luck! Please rate my reply. Thank you.

I would like to connect the audio from my Comcast DVR via digital optical thru the TV/SAT IN optical on the receiver at the same time I have a composite connection via the TV RCA composite jacks. ( This...

I'm a little confused by your use of 'composite' with audio, as in "Does anyone know what would happen if I ran both composite audio and optical audio both to their respective TV/SAT IN input jacks on the STRDE935 ?". What is composite audio?

The manual claims on page 48 that you can't record digital audio out to the analog REC OUT jacks.

I say 'claims' because the engineers or manual writers clearly are not as creative as you are in trying to wring as much utility out if this unit as possible.

I can't find an answer but I would offer this - if you are recording anything though any AVR, as soon as you choose to monitor the audio the digital input is usually disabled.

And I would be curous to hear more about what you're doing and how you finally achieve it.

How to connect the herman kardon AVR 260

I have a AVR 247 and a AVR 347 there is a HDMI output on the back this will go direct to your HD TV HDMI input. If you have a HDMI output on your SAT. box then run this to the receiver HDMI 1 input. If you dont have a HDMI output on your SAT. box, then you want to use the digital fiber optic output from your SAT box and run it to OPT 1 input on the back of the receiver. This will be for audio only from the TV but thats all you want anyways. Be sure to set your receiver to HDMI 1 OPT 1 for this option. PS. This is a very clean and nice sounding receiver the only flaw to these receivers are the amount of heat they generate even on very low volumes. You must get a 4 or 5 inch boxer 120 volt fan and set on top of receiver blowing down and plug it in the back of receiver on the switched plug outlet so it comes on when powered up. This will make your receiver last 10 times longer. i have had mine for 3 years now and run them very hard sometimes with no problems with this fan addition. Hope this helps good luck.

My HDMI set top box display reads "no input signal" but everything appears connected. I have no picture or sound. Cannot access any tv stations.

Make sure TV is set to HDMI channel.

Try a different HDMI port on back of TV.

Reset the cable/sat box and reset the TV by powering off both and unplugging them for the wall outlet for 30 seconds. Turn cable/sat box on first, and then TV after 30 secs.

If this fails, check the TV manufacturer's website to see if they have any software upgrades that will resolve the HDMI issue.

Optical inputs

In short yes!

If you have two optical inputs and two equipment (PS3 and HDVD) then you shouldnt have a problem at all. Just make sure you change the mode of the receiver to TV/SAT when you want to use the HDDVD. Your problem may be the video out put.

If i was you i would do the following:

1. Get rid of all your optical cables as you won't need it.
2. If your receiver support HDMI then by default HDMI will send both video and digital sound.
3. Plug the HDMI of the PS3 to the HDMI input of the receiver, plug the HDMI of the HDDVD player into the HDMI 2 of the receiver and plug 1 HDMI cable from the receiver to the tv/monitor you have.

That is the best set up so when you play PS3 you select dvd/ld and when you watch hddvd you select tv/sat.

However having said all that the fact that you have dvd/ld suggests you actually don't have HDMI at all on the receiver(...i just checked the specs of the receiver). Which means you will need to have 2 hdmi inputs for your tv and you will need to have the 2 optical connections.

But in short yes to your question.

hope this is not too confusing.

good luck
