Question about Onkyo TX-NR801 Receiver

Rear left channel not working on Onkyo NR801

There is no sound coming from my rear left channel. First, the sound was intermittent. Now, there is no sound coming from that speaker at all. I've ruled out wires and speaker because when the same wire and speaker are attached to a different channel, they work fine. What could be causing this and can this be fixed myself or outside cheaply? Unfortunately, the receiver is out of warranty. Please help. Thanks in advance.

Re: Rear left channel not working on Onkyo NR801

Sounds as if it's time for a shop visit, unless you want to try this yourself. The panel connection on the rear of the receiver, or the protection relay have apparently come loose from the circuit board. It happens sometimes when stress causes the cabling to pull on the back of the unit..accordianman

No surround sound on rear speakers and cant access speaker set up functions. left front channel not working when rears set up without surround

from the problem description, it sounds like a wiring/setup problem with the speakers. check to make sure you are only using the main 'a' front r & l speaker connectors. if you select speaker set a + b on the front, you will not have the rear channels. please see the speaker connection guidelines in the manual on page 13-15. make sure the audessey mike and/or headphones are not plugged in when trying to use the speaker set up function.

I have a n onkyo av reciever ht-r560 only the front 3 speakers go on when im using it i know the rest work and are plugged in correctly because the volume tester outputs sound through it. Is there an on...

Your sound might not be working because the HDMI and optical audio inputs might not be working.

I made the mistake of buying the Onkyo HT-560 and in less than two years all of the HDMI video inputs started intermittently breaking. Sometimes when you selected the channel both the image and the sound would not come though.

Also the rear speakers stopped working from time to time and I have to run the setup again to get them to turn back on.

I am not sure that Onkyo was ready to introduce this technology, it has been a nightmare and my stereo is going to cost almost as much as I bought it for to fix it.

Oh and there customer service was no help, they just told to bring it to an "authorized service center for repair". They had also had no idea where there was one in my city it took them a day to get back to me.

The Onkyo HT-S5100 looks almost identical to the HT-560 not sure if they are different in anyway.

Stay away from Onkyo in the future! I know I will.

What Blu Ray to buy for ONKYO TX-NR801 for Dolby TrueHD, etc???

Hi, as the Onkyo receiver you have does not have HDMI switching, the only thing it will do for you with a Blu-Ray player is process the audio signals.  The video from the BR player will have to go directly to an HDMI input of your hi def TV.  In this case, either Sony or Panasonic BR player will be equal.  Assuming you keep the Onkyo unit you have, you would want to use the optical digital output from the BR player as the audio source into one of the optical, digital audio inputs on the Onkyo.  In an ideal world, your receiver would some that does do HDMI switching.  This way, all the audio and video signals from any audio or video source would be automatically switched and channeled through 1 simple HDMI cable into your hi def TV.  This will make you life simpler as ther would be no need to select an appropriate input on the TV, as well as one on the receiver.  That said, buying a new receiver in addition to a BR player is more costly.  Good luck.  Let us know how it goes.

Onkyo tx-nr801 net tune setup help

Below is the sequence that I made it work

1. download the latest firmware for tx-nr801 and net-tune central software at Onkyo website as shown below:
Click on "User Identification" at the bottom
(You'll need the serial number shown at the back of TX-NR801
to download it)

2. disable firewall in your PC or notebook and start
updating the firmware for tx-nr801
If firewall can't be disable, you probably can't go through this.
This step takes about 30 min.

(There is a document showing how to do this with the download)

3. keep disabling firewall in your PC (notebook) and install net-tune central (there is similar document describing the procedure too)

4. By pressing Net-Audio on remote controller (it can switch between mServer and iRadio fucntions if you keep pressing this button)

Left rear surround channel sometimes doesn't work

If your receiver has speaker protection relays and they are intermittent due to bad contacts you might be able to repair them if they are not sealed. Most are but take a shot. They make small files for this purpose. Replacing them can be daunting because yo may not have good access. Tap the relay with the receiver playing and see if it helps.

So your saying that you have no rear channel. Some recivers use a single stereo output ic for both sides on the rear speakers. you could have a defect with this IC . Anther thing Im sure you check3ed the obvious ie : the switch is on suround sound? If there is a front to rear fader is it in the middle? Good Luck
