Question about Onkyo TX-NR1000 Receiver

3 Answers

Audio suddenly died on my TX-NR1000... but the receiver stayed on

I had the TX-NR1000 off and disconnected for two weeks while on vacation to protect it from power surges and such. When I reconnected the receiver,it worked fine for a couple hours and then the sound went away while watching/listening to Sat TV. The receiver remained on and all switching functions worked, only no sound (not even the test tone) from any source and to neither A or B speakers. I turned it off and on and sound came back for a minute and then it was gone again. On my second try it didn't come back at all. IF I set it for Direct Audio there is sound. So it would seem that the problem is in the DSP, what do you think? I have already tried: disconnecting all speakers and external sources, initializing the receiver, letting it connected for a couple of days, disconnected for a few days... I do have the Service Manual in case you want to point me to a section in there. Thank you!

    The Receiver COMES ON and switches functions, but NO SOUND comes out through the speakers or headphone. I wonder if one of the DSP boards died...

This receiver has an over heat problem with its HDMI board. The replacement board includes a small daughter board upgrade. On EBay there are people who will trade out new board for your old one about $250.

Onyko tx nr616 receiver keeps shutting off. Only stays on for approximately 3 seconds. Can you help?

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

I have a ps3 going to hdmi 1 on my receiver, and hdmi out from receiver to tv, i cant get audio or video. what am i missing?

Depending on your TV and what input/outputs you have, you are almost always better off to run any video componenets through TV first then, audio out to receiver. In other words, run your HDMI out frim PS3 to TV then, digital optical out to receiver. If you have the capability to do so, you can run all you video componenets to TV, ie: sat/cable, DVD, etc., to TV with only one audio out to your receiver. You can use your TV's menu to select what you watch and you would only have the one audio out to receiver, you then just have to use the receivers menu to choose the proper channel to listen.

Onkyo tx sr605 stopped playing music what should i do

If the receiver is indicating "overload" or "protect" there is a load on the system. Turn the receiver off and remove all speakers and wires, turn receiver on and reduce the volume right down, if the word "overload or protect" stays off! it means there is a short in the wiring or one of the speakers. If however the word "overload or protect" comes on when turned on, it indicates a short in one or more of the audio output ic's in your receiver, this is where you will need a tv technician to troubleshoot further. If you not sure about checking it out just call a professional in to have the unit assessed.

Hey , with the Onkyo TX-NR1000 can I get started plugging two speaker while I gather enough money to buy the surround sound speakers. Also your opinion on speaker choices is greatly appreciated. Thank you.

Sure you can only connect 2 speakers. As for brand recommendation Polk audio makes some fine sounding speakers also Klipsch, Boston acoustics, too many to suggest. If you have a Best Buy near you they usually have a speaker room with many different brands that you can listen to. Though that doesn't mean you have to buy them their. I'm partial to Polk audio though. Polk has excellent customer service. That's going to be a tough decision you should really do some research on the internet for cost to quality references. Good luck. I hope this gets you pointed in the right direction.

It overheated, due to lack of ventilation. Now in protective mode

Disconnect all speakers at the receiver, if it stays on, post a comment and I can help you troubleshoot further. If it stays in "protect" it needs serviced. Hope this helps.

Onkyo tx-sr602 as soon as i turn receiver on it flashes protect

Does it display any message like "Protect" or something similar? Do you hear a relay click on then off?

Did the amp just not power up one day or did it stop working while you were listening to it? Finally, do you have teenage kids who might have been listening to your receiver and would have "neglected" to tell you that after listening to their music it suddenly stopped working?

It could be an internal fuse but chances are its something that requires a technician to repair (like the output transistors).

Amp protection circuit

disconnect all speaker leads at the unit,power it up then see if it'll stay on. if it does, reinstall one speaker lead at a time until it goes into protect mode. that speaker line will probably have a short in it. Just run a peice of skr wire straight from the unit to the sspeaker in doubt, hooks em up see what happens. if it shuts down have that skr ckd.if it works, just rip out the old shorted line and run new stuff.
