Question about Onkyo TX-SR304 Receiver

Receiver says center channel unavailable

When I first bought it, the center channel worked. I now want to connect just my Vizio TV input via digital optical line, then out to 5 speakers. The side speakers work, but now the center channel is "unavailable?" Could it be a fuse? Does it have fuses? There is no mention of fuses in the manual (which is not the greatest manual I've ever seen.)

It may be the surround mode you are in. Some modes do not use the center channel. Try changing to a pro logic mode, these will almost always use the center

    It is unavailable in ALL modes. That's why I suspected a fuse. But I don't want to risk opening the thing up if there aren't any fuses.

  • Steve K Jan 23, 2013

    there are no fuses that would cause a problem like that. I would say to try and do a factory reset on the unit to make sure it is not just a settings being wrong.

  • Steve K Jan 23, 2013

    You can reset it by holding the VIDEO 1 button and pressing power. CLEAR should show up in the display. After that, all settings are back to the way it comes from the factory.

    I will try that this evening. Thanks!

  • Arthur Demers Jan 25, 2013

    Did NOT help. It did reset but I still don't have the center channel available. May have to bite the bullet and buy a new receiver. Dang.

  • Steve K Jan 25, 2013

    Here's another thought....it states in the manual that if speaker set B is turned on, then speaker set A is stepped down to 2.1 only. Do you have front B speakers turned on? The unit probably only has 5 amps channels, and if B is on, then it is using the surround amps in order to drive it.

SOURCE: Onkyo TX-SR304S 5.1- Popping Issue

I called Onkyo support regarding the issue with the clicking/popping noise and they said that that's normal when you change channels that are digital. They don't seem to think that it's a defect.

SOURCE: Onkyo TX-SR605 conected to Mitsubishi DLP TV

What I think I did and how I fixed it!

FACTORY RESET ON EVERYTHING!



All you have to do is to do a factory reset on everything, but I thing mostly on your 605, but I would do it on the TV as well. I think what had happened is after I set everything up for the first time, it worked great. As the days when on I started to play with all of the futures the 605 and the TV had to offer. I was turning them on and off to see what everything did. What I think I did was, I turned on something in the 605 that the TV did not know how to cope with. If I had to guess, I think it is the Lip-sink feature (Spelling?) in the 605.

Anyway disconnect everything, look in your manuals of the TV and the 605 to see how to do the factory reset on both. Then turn your TV on. After it does it’s start up for the first time (again), start connecting the 605.

It has been working great for me after I did this. Do not count on help from the people you bought it from or the people who made it. This stuff is so new they do not really know how to fix it.

SOURCE: hdmi or optical

There are no noticable differences between HDMI and optical except price. Although optical is less prone to EFM interference, HDMI can carry a wider bandwidth, depending on quality, but cost a lot especially long runs (10 ft or more). Also optical cables are not prone to connector tarnish which occurs even with gold pins of HDMI

SOURCE: Switching digital inputs with a remote?

The default assignments for the digital INPUTs to Source names are:

OPT1= Video2
OPT2= CD.

If you have never changed them you should be able to select the PS3 by choosing Video2 and the 360 by choosing CD.

Or you could go into the setup routine on Page 33 of the manual and assign each digital input to a different 'function' that works better for you.

By the way, if you have the choice of coaxial vs optical cables on a given device the cheaper, longer and least sensitive-to-dirt-and-damage choice is coaxial - plain RCA cables. You can even extend them with Male-Female extender cables or split them with Y-cables for sharing one port with two devices or one device feeding two other devices (example: Cable Box-to-TV-and-Receiver). Just don't have two sources feeding one input turned on at the same time or they'll interfere with each other. Try that with optical cables.

SOURCE: Onkyo TX-SR606 getting no sound from HDMI sources

Not sure if this is your fix, but I had what I thought was the same problem. I played with my Onkyo quite a bit ensuring the correct assignments for HDMI, audio and all that stuff. Turns out I neglected to make sure the output devices were properly assigned. Many devices aren't default to output sound over HDMI. I changed the audio out settings on the cable box to HDMI and suddenly the Onkyo worked great. I know, I'm an idiot for not checking that in the first place, but maybe someone out there is having the same trouble as well.

Cant get tv audio through receiver directly (without satallite, Game, DVD connection)


If your TV doesn't support audio return channel (ARC, which is your TV audio routed back to the receiver through the same HDMI cable), you then need to connect your television audio-out to your Onkyo TV audio input, using a digital cable or an analog one according to the connections on the back of your TV. If you use a digital connection (optical or coaxial), make sure you have the proper digital port assigned to TV on the onkyo I/O assign menu/digital inputs.
In case your TV does support ARC, you need to activate it in the Onkyo's hardware/HDMI setup menu, either by turning on HDMI control (tv or receiver control each other via cable), or by turning ARC on (you'd probably need to activate ARC on your TV as well).
Hope this help,

Have new E370VL hooked up to Dish Network via coax. The picture jumps/blips? Connections are tight. Help.


This can happen when there is radio interference near the coaxial cables. Sometimes the interference is behind walls. The solution is to try a different combination of modulation and channel than what the DISH receiver is current set.

The DISH menu screen for this setting is Menu-6-1-5. With dual-tuner receivers, typically "TV 1 Out" is the TV that is connected in the same room as the receiver is located. "TV 2 Out" is the tuner that is fed to the remote TV via backfed coaxial signal.

All that needs to be done is to change the channel and mode going to the effected TV to something different. If your channel/mode is currently set to Air/60, try changing it to Cable/73. When you change the mode/channel in the DISH receiver, you need to set the remote TV to the same mode and channel.

Keep in mind that with some TV companies like VIZIO, they call their "Air" mode "Antenna". With VIZIO's the TV must be set on TV input and then go into the Menu to the Settings, Tuner Settings. Change mode type to match what you are trying on the DISH receiver, exit the VIZIO menu and manually enter the channel number.

Eventually with trial and error, you will find a mode/channel combination that isn't effected by your particular environmental interference.

I can not find the channel for Dish Network.


This hopefully is resolved for you, but here are some easy steps if you ever run into this problem again. If you are at TV1 where the receiver box is located:
You want to make sure that the tv is on channel 3 or 4, and usually on an input. Since the tv says Channel unavailable, it sounds like you do need to be on an input. Try video 1 or 2, or cycle through your inputs.
If you are at TV2
You will want to make sure that your tv is on channel 60 or 73, and you will want to make sure that the receiver box has 3 lights on the front. (Blue, green, yellow.) You will need all 3 lights ont he receiver box for the TV2 to show a picture. I hope that this helps.

Denon AVR-682 center channel has no output


You may have had the receiver set to "Stereo" mode, or Analog instead of "Digital" or "Auto" (automatically switches to digital when it detects a signal) modes. Also, setting it to "Direct" (2-channel from an analog source) could result in loss of center channel. Or your Surround Parameter dial (on the higher-end Denons, at least) could be set to a 2-channel mode.
Finally, if your digital inputs are incorrectly assigned (e.g., COAX1 instead of OPT1, or OPT2 instead of OPT1) for that source, the receiver will use the Analog signal which is stereo-only. You could get a center channel via Dolby Pro Logic II but it would be a "matrixed" signal, not the "real" center channel you could get via digital input using Dolby Digital or DTS.
(If all else fails, re-check your center channel speaker wire connections. It's very unlikely, but also possible, that either the receiver center channel amp or the speaker has failed.)

I just bought a yamaha rx-v365 receiver and hooked to my cable box via a hdmi and optic audio cable. this is working fine but i cant get a dvd player to work via a component and coax audio cable. neither...


Make sure that the DVD player is connected into the correct inputs on the receiver and that the receiver also has the correct input selected to play. If your TV also has component video inputs it is best to connect the player directly to the TV. Otherwise, make sure you have the TV connected to the receiver via component video out.

Connect home theatre to 32" lcd to ps3


Depending on the year of your model of VIZIO your digital optical output may be tied to the DTV input only. Meaning the only time you will have audio coming out of the digital optical output is when your using the tuner and your on a digital channel. If your television is newer and the digital optical output is in white on the back of the television than it is tied to HDMI and the DTV Tuner and you will pass audio through the digital optical output when using HDMI or the Digital Tuner.

Now to get connect the HT: Normally you would run a digital optical cable from the source device to the home theatre system. Meaning if it was a PS3 you would run a optical cable from the Digital Out on the back of the PS3 to the Digital In on the Home Theatre receiver. If it was a DVD player than you would run the optical cable from the DVD player to the HT receiver. If you have a newer VIZIO and the optical output is in white and not black than you can run HDMI from the PS3 to the VIZIO and then run a optical cable from the VIZIO to the Home theater receiver.

You will have to adjust the audio setting in the PS3 to run audio out of the HDMI port if it is set to run audio out of the Digital Out or AV out. Also, if your going to run audio from the PS3 to the HT receiver through the Digital Out then you need to change the audio setting in the PS3 to Digital Out.

1. Select (Sound Settings) under (Settings) in the home menu.
2. Select [Audio Output Settings].
3. Select the input connector on the audio device.

Channel numbers and audio formats that are supported vary depending on the connector in use. AV is 2 ch. only, Digital Out is 2 ch. & 5.1 ch, and HDMI is upto 7.1.

Vizio 42" LCD. Flat screen. Won't display CC on setup screen using HDMI input. Have a Sharp tv on another Directv box and it shows CC via HDMI connection. Problem with receiver or with TV? Costco's "Help"...


CC is a feature of the TV. All TVs are different in features and the Vizio is limited on its features due to cost. To eliminate the directv receiver connected to Vizio TV just swap with the receiver connected to Sharp TV and see if CC is displayed.

Yamaha rx-v2500 receiver how to hook up speakers


HI,

Follow these steps to connect a powered sub woofer to your receiver: You typically have two options when connecting a powered sub woofer. Input (1) on the rear of the sub woofer would be used when connecting the sub woofer to the receiver using speaker wires. You would then connect the main speakers to the opposite end, or output or the sub woofer to the main speakers. Option (2) would be using RCA line level output jacks, input (2) on the rear panel of the sub woofer directly to the single sub woofer output on the back of an AV receiver. blank.gif
