Question about Onkyo TX-SR803 Receiver

Open Question

NO output sound

Everything working fine but not sound to the speakers; yesterday was a general power interrupted while a storm (over voltage when returned ??
Lightning damage ??) I'm not sure that was the really reason of the malfunction because there were a lot of other electronics in the same line and they are working fine (Xbox, TV, DVD player)
I opened the chassis and check all fuses and they where all ok
All the function seem on the display work fine, only no sound output
When I turned on, it makes the usual relays clicks sound.
I test second zone and pure audio but nothing
I test with various sources: FM tuner, two different CDplayers but nothing!

SOURCE: reciever shutting off

To: "mrlong86"
This idicates problem with output circuitry. Have unit checked out by pro/tech

To: "flyhigabe"
You indicate you have speaker spliced in with another(?)
This changes the impedence which may be too low for amp to handle. It may cause amp to shut down to stanby.

SOURCE: Lost Audio via HDMI

Check the pins on HDMI cable at both ends. Check for bent or broken pins. If all are OK, re insert firmly. Retry

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.

SOURCE: Zone 2 speakers only work with the tuner - no


zone 2 will only work with analog sources so if your dvd, cable and other devices are connected via HDMI, that alone won't work. What you need to do is hook up RCA (red and white) cables from the dvd player to dvd in of the receiver and same thing for your satellite box (and other sources.) no need to change any setting on the receiver. This way, the HDMI will take care of your main room speakers and the RCA will feed your zone 2 speakers.

Hope this helps.

SOURCE: Problems with optical input

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

SOURCE: 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.

There is power to the unit but no sound coming. All connections are in tact per yesterday when it was working

Possible that the amplifier has a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speaker

I have no sound coming out of receiver all of a sudden. Connected speakers to another radio and speakers work fine. Everything looks fine on receiver just no sound. Oh, and the mute button is not on.

It is an indication that you have a faulty output ic.
Output ic is responsible for amplifying the audio from your reciever to sound output which is converted by your speakers.

If you're output ic is defective then definitely you haven't sound produce even your unit is working.

I've advice you to look for a qualified technician to checked the condition of your output ic and do some re-soldering for some dry joints on the board.

Thanks for using fixya...

Yamaha RX-V365 Receiver when I hook up my center channel it is not audible at all. The R and L speakers work fine when they were located in the FRONT A and FRONT B terminals, but when I moved everything to...

With what signal did you try? Maybe your signal source (DVD/TV or radio) didn't contain any sounds for the center channel.
Go to the Setup menu, Speaker setup / Manual setup and find there item called "Test tone". It will output a test tone to each speaker individually (you will see on LCD which speaker is being tested at each moment). If you will hear a sound from the center now, there is no issue and center is working fine, just your source didn't contain any sound for the center.

If it doesn't work, then either you have faulty cable, faulty speaker or faulty center output of the receiver.
- Try connecting the center speaker to different output of receiver (this will test if speaker is OK).
- Try connecting working LEFT speaker to left output with CENTER cable (this will test if cable is OK).
- Try connecting working LEFT speaker with working cable to the CENTER output (this will test the output of receiver if OK - but use the Test Tone from Setup).

Sony STR DE 197 Reciever with No Sound

I have the same unit. My best recommendation would be to remove all speaker wiring, and try new wiring with another pr of speakers,since the "outdoor " speakers were rained on. the protect mode that the unit went into sounds like it did because the speaker outputs were shorted due to the rain, so ensure that the speaker output terminals are not shorted and dry...also see if output is still availalable at the headphone jack...if it is, the pre-amp section is still good , in which case the protect mode and no volume output out of the speaker jacks may mean that youve blown the ouput trasnsistor finals.
I hope this helps.

I have a pioneer 5.1 channel surround sound system and it powers up and everything seems to go fine but you go to turn it up and no sound comes out of the speakers already checked speaker wire connections...

Does the protection relay click 3 to 5 seconds after initial power on??? If not, your unit is staying in "protect" mode to save your speakers because the output transistors or output IC is shorted and sending 40 to 60 volts at your speakers. Not a good thing, but at least it saves your speakers.
Good Luck!

Denon DRA-25/25L Stereo Receiver. On power up the display lights but no sound is produced by the unit. When working normally a click (relay?) is heard about 5secs after power up and normal speaker output...

Without looking at the schematics for this particular model, I'd surmise that the click is indeed a speaker protection relay. Generally this is fed by a number of different sense circuits that watch for power amp issues and/or excess speaker current and/or power supply output stability. Although the relays do indeed fail at times, generally it is not the relay that is at fault. If you have a scope and a schematic, you can check the various circuits that feed the relay for the exact cause. If not, you can do some experiments that might help deduce the problem: e.g. do headphones work when speakers do not, does the relay click on when no speakers are connected (or selected), etc. In my experience, it is most often the output transistor(s) in the power amp. But not always ;-)

No sound

1. check if the amp is in PROTECTION mode (might be a bad speaker or shorted output)
2. check the 'MUTE' switch
3. try to use the FM/AM mode to isolate an input source. If there is sound then check input source.
4. ...still no sound have a techinician check it.

No sound

If you have a constant 2.49 volts on the speaker output Im surprised that your speakers are not smoking or making a BIG racket!!!? Sorry my friend you must have measured wrong as if you had a constant voltage on the speaker output, unluss the unit is a real cheapo unit, you wouldnt have speakers left or you would have smoke, as there should never be any DC voltage on the speaker outputs and if it was an ac voltage it would be making a big noise. Sounds like you should get a new unit or take this one into a repair shop. Good Luck
