Onkyo txds797 sound problems

Did you eer encountered a problem wherein no sound/audio is heared on both analog and digital domain even I switch from one sourcechannel to another. I can see a display wherein the reciver detects a signal i.e. pcm or dolby but does not enclosed in a red box display. Intermittent sometimes it will produce sound and afterwards it will not.
Any ideas. Technical service Bulletin from onkyo?... thanks

    possible problem will be on the speaker relay ckt. as discussed in onkyo's service bulletin. 
    "When the speaker relays are activated, the collector of Q231 and Q232 should drop to near 0Vdc. Voltage can be monitored at terminal P6830 and P6832. Q231 supports RL6600, RL6602 and RL6603, where as Q232 supports RL6605 for Zone 2 operation. If the DVC at P6830 collector or its follower terminal is HIGH, it should be an open transistor Q231." 





    You can try to resolder the above q231and q232 transistors. It might solve the problem.

SOURCE: Onkyo TX-SR500 Dolby Digital problem

I just read over the problem you were having with your Onkyo TX-SR500 receiver. It sound like the unit needs to be setup for all five channels.Sence your symptom says the diplay shows Dolby D3/2.1. According to the owners manual with the remote control look for speaker setup whin the button is pressed the current speaker setup will be shown in the display. Press the preset/adjustment<> to change the current setting to five speakers. the listening mode will automatically change according to the number of channels you selected. Hope this helps.

SOURCE: Source always PCM, can't get Dolby-D

Hey, you have to set up the SOURCE to use bitstream instead of PCM. For instance, in my case, I had to configure my DVD player to output audio in bitstream. Then the receiver was perfectly happy, decoding Dolby D as it should.

SOURCE: PCM vs Dolby Digital

OK, I just figured this out. Go to the audio options in your DVD player and switch from pcm to bitstream. Now my movies sound right again.

SOURCE: No surround sound from my PS3 through the Onkyo 5100. Video OK

Unfortunately only the higher end Onkyo Reciever pass audio over HDMI for sound. 605,705,805,905 exc. Your reciever will carry Video over HDMI but you will need a digital optical cable for sound.



thanks.

SOURCE: hello. I have some problems with

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

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,

Wire Kenwood GE 7030 equilizer to onkyo tx sr504 receiver


The manuals explain it.

http://www.retrevo.com/support/Onkyo-TX-SR504-Receivers-manual/id/365ag215/t/2/

For all practical purposes an EQ or any analog audio processor connects exactly like a Tape Deck - into any RCA pairing that has both an OUT and an IN and can be selected to be in or out of the audio path.

However, on this and just about any modern digital-capable AV Receiver, activation of any external loop that would connect a processor or tape deck would automatically DISable any digital audio sources. The effects of the processor, therefore, can only be used with analog stereo sources. It WILL affect the sound going to all speakers if you use the various Digital Sound Porcessing modes as the extra channels are derived from the stereo channels anyway.

I have a Onkyo TX-SR604 Receiver. I get no sound


Hello Fixya customer,

Thank you for your question.

A point to keep in mind here is that Zone II will only feed through an analog source. Since the Video 1 input is using the digital (coax, optical) input that that is your most likely issue.

Thank you for using Fixya, and please let me know if I can firther assist.

I have an audio problem with my TX-SR502.


If your remote also controls the Cable Box you might want to look at its audio settings. Maybe you muted it.

BTW: it would be a good idea to also run video and analog audio from the cable box directly to the TV if it has speakers so you can watch and listen independent of the Onkyo.

Problems with optical input. I am having intermittent problems with the optical sound input on my Onkyo. I am using a DVR with optical output for the source. Sometimes when I turn the DVR and Onkyo on I...


sometimes with cable, satellite, or any dvr, the digital signal actually is intermittent and there is little we can do about it but add an analog audio connection for each device as a backup. per se, and put the receiver in auto input mode. the receiver will utilize the analog signal to fill in where the digital signal fails
good luck

No sound when dvd input is selected on onkio tx-ds696


Make sure your DVD setting is looking at the right audio inputs. Usually there is a menu option or a button to toggle from analog or digital input. Usually when no-sound but video ok, you have the wrong input-type selected. If you are using 2 RCS's (red/white) then you want ANALOG input mode. If you are usung a single RCA (orange) or a fiber optic input for audio, you want DIGITAL input selected. If digital os selected, make sure you plug into the correct digital input to hear. If it does not work at first, mofe the jack/fiber around into the different inputs untill you hear sound, then you will know which port is associated with the DVD setting. Unless it is self evident feom the menu.

No audio on any channel, even in audio setup mode, no audio headp


If you have any of its sound outputs connected to a TV or tape deck do they get the signal? If so, then we know there is sound processing somewhere inside the unit but not emerging to anyplace that requires amplification.

A quick basic check would be to tune an FM station, run an RCA cable pair from the audio output for a tape deck (see the picture at the link) to an analog audio input on your TV. Select that input on the TV and you shouls hear the FM station, or anything the receiver is configured to play. If it's silent then there is no audio signal circulating in the receiver to get out to the amplifiers.

http://www.onkyousa.com/images/hookup/TX-SR803/detail_tapedeck.jpg

Check to make sure Multi-Channel input is not selected unless that is what you're listening to as it bypasses all other sources analog and digital EXCEPT the tape; and check any Mute or Zone Controls, too.

If you hear the program on the TV but not through any attached speakers, then the amplifiers are all disabled for some reason. The click I asked about before... when you turn it on does it get a click about 5 seconds later. That would be the protection circuitry turning OFF to allow the amplifiers to function.

I notice it has a Tape function. Make sure it isn't selected as it assumes a tape deck or processor is attached and will only play back what would be coming FROM the tape deck or processor. On my Pioneer receiver it also disables any digital signal processing.

Sometimes when I'm watching TV with the remote on the seat someone moves and something bad happens. It's always some unfamiliar button that gets touched unintentionally. Look over the remote for things like MUTE, Multi-CH, Tape.

TX-SR919 THX has an "FS ERROR" from the optical in connected to my Blu-Ray player (PS 3). Sound comes out fine, but I don't know what the "FS ERROR" is.


I had this problem as well. In short the digital audio port id out-dated. You will need to buy an analog converter or an Onkyo ED-301 sound processor.

Analog RCA input to HDMI output?


You have said the correct thing HDMI is digital therefore Analog will not pass.
You might have RCA audio outputs on your cable box so either send them into the TV from cable or into the AMP then use AMP volume to listen to TV audio (select unused input and remember it is for TV) the key is to remember that cable box will drive the initial vol so raise or lower cable vol then use AMP vol to obtain desired volume.
