ONKYO HT-SR 875 RECEIVER : NO AUDIO

At risk of being insulting, is there a speaker selector switch which may have inadvertently been switched off?

There are many sensors inside which monitor various voltages, temperatures, etc. and any of them could shut down the amp but that's generally what happens: the amp goes into a powerdown safe mode, often with some sort of diagnostic code displayed on the outside with a series of flashes or the like. If everything appears to work, I'd start with the speaker protection relay. When the power is applied, do you hear a "click" a few seconds later?

Yea ,i checked all the speaker switches it's not that , and it shows no error reading of any kind.There is no clicking, just nothing. I had another receiver that went into protect mode but, what it did when you powered it up was to go into standby mode after about 5 sec. this receiver stays on and acts totally normal except no sound. Looks like i'm going to have to pull out the bank roll and take it to a tech. I took the top off of it last night and it scared the hell out of me.What does all that stuff do?

OH, sorry thanks for the help.

It strikes me as odd that there is no sound whatsoever for any source.

Try this...

Set the receiver for plain stereo, with no surround, enhancement, signal processing, or anything. Attach a stereo source to one of the stereo inputs. Do you get anything?

This must be a pretty new model. Is it still under warranty? It's at least a

If you bought it online Onkyo customer service will still probably authorize a one-time repair under warranty.

P.S.

That should probably be a TX-SR875 model number. The "HT" probably refers to the home theater system of which the receiver is one part.

Unlikely you can fix this yourself anyway, unless you are a tech and pretty well versed in modern surround receivers.

Did you go into the source menu of your receiver and check that the audio is set for HDMI? You can also try a separate coax or optical cable from your Blu-Ray player to your receiver and see if the audio works that way. (Of course, you'll need to make the appropriate change in the audio select menu if you change it.)

Good luck.

Here's a good question: did it EVER work? I mean, did it work fine one day and not the next? If it's never worked I'd definitely go through the setup procedure at the beginning of the manual, there are lots of settings in there that could make it non-functional for one reason or another. The fact that you're getting no error codes strongly indicates that it's not broken, just perhaps set up wrong.

Dave,I messed with it again last night and i noticed a click about 2 sec. after i turned it on. So, it might be going into safe mode but, i still haven't seen any error code. I bought the receiver like this. I figured it was something minor but ,i m not a tech either. I didn't pay that much for it so i can put alittle into it . Suggested retail for this receiver is $1599.00

The click is a GOOD thing, it means that the speaker relay is engaging. There is a delay which allows the amp to stabilize before the speakers are switched on. It also disconnects the speakers if a problem is detected such as DC voltage on the outputs.

If it's never worked, it could be any number of things. If you've never worked on HT receivers, you will need to bring it to a tech. I've dabbled in electronics for many years, have repaired lots of TV's, stereos, all sorts of other stuff but I don't touch these things, they are too complicated, impossible to diagnose without a service manual. An experienced tech could probably diagnose the problem is about a thousandth of the time it would likely take you or me. If you can find one.

If it were mine, I'd probably open it up and see what it uses for outputs, and see what tests could be performed on them. With a service manual I'd likely be tempted to trace the input signal and see where it dies, at least which BOARD it disappears on. It might turn out to be something simple, who knows.

Another poster suggested you turn off all the digital stuff, set everything to neutral so as to minimize the signal path and hopefully bypass things like the DSP board... you did that, right? No effects, no DTR, no DD, nuttin'?

I'd start from square one. Get out the owner's manual, http://63.148.251.135/redirect_service.cfm?type=own_manuals&file=TX-SR805_875_B_En.pdf Disconnect all the wires. Hook up your speakers as shown in the manual. Go into setup and test the speaker levels. Or you can use the microphone that comes with the unit and plug it into the jack in the front of the receiver and it will automatically set the levels. Again, see the manual for instructions on this. If you can make it past this point, then hook up a dvd player AND either a coax or optical digital cable between the receiver and dvd player. Go back into the setup menu (remove the microphone) and make the appropriate settings to the audio select input menu. Please report your findings.

Good luck.
