20 Most Recent Onkyo TXNR808 Receiver Questions & Answers

Hello, I am sorry about your issue. Please contact Onkyo at 800-229-1687 option #3 so that we can discuss options. Thank you, Onkyo USA.

Amps shut down in most cases because the receiver is detecting and impedance (below 4 ohms) that might damage the amplifier. Do a quick check of the speaker connection and look for wires that might be shorted to the frame or have crossed each other. This is the most common cause of the unit shutting down. Check your speakers impedance if you have a meter. If you don't then unplug power from the unit and then un-hook all speaker wires from the receiver. Next connect just one speaker (Front Left) and power the unit back on and take the volume up. If it shuts down then try the Front right all by itself, bring the volume up again. If the unit seems ok then add one speaker at a time and test. Continue until you find the bad speaker/cable. Your amp should be able to drive speakers down to 4 ohms. The NR808 has power monitoring (sometimes called crowbar) that looks for to much current and then shuts down. I suspect you may have a short in a cable or in a speaker. The 808 is a great amp and hopefully your problem is external. If your amp continues to shut down even with just one speaker connected then one or more of your channel amps (internal) is likley bad causing the unit to shut down. Good Luck.

This problem could be caused by a lot of things. The remote control not working could be as a result of the batteries so get replacement batteries.If the batteries are not the problem then the remote is old and due for replacement.
The receiver on the other hand is having the problems it is having due to either old age or there is a malfunction in the unit control board which controls the functions. Simply get the unit serviced at the local dealer so it functions properly again.
Hope this solution has been helpful?

Nope.. 8 ohm's is the best speaker for it, anyway. receiver will run coler just leave the settings as default. it just means that any speaker above 4ohm is ok to use it. but if you use a 2ohm you will burn the amp..* ohm is perfect. for this amp.

Have you defined the presence of the center speaker, like you will also have to do for the sub when you get one?

The problem is the audio output ic's, one or more channels has developed a short causing the safety shutdown to engage. The only solution is take it back where it was purchased and since it is under warranty it should be repaired free of charge if not a possible exchange.

The 0-83 error indicates a problem with the firmware update. Try resetting the receiver's BIOS by following these steps2: Unplug all cables Un-Power the receiver Power the receiver Before the receiver gets into the "Enter for updating" message, press Tone + CBL/SAT + ON/STANDBY. This will show you either the volume numbers or get you into settings of the receiver's speaker configuration. Press CBL/SAT + ON/STANDBY. This will clear the BIOS and show a "Clear" message on the display. Wait until you hear a couple of clicking sounds for the receiver to turn on and off the power.

Hello Did you update the AVR over the internet? If so the device wont work anymore. You need to service the device in a nearest Onkyo service department. Regards

Hello, To test the subwoofer when the blue light is on if you apply your thumb to the end of the subwoofer cable (the end that you would plug into the receiver) there should be feedback from the sub. If there is no feedback then the sub is not working correctly. Thanks, FJD

You need a RCA sub-woofer cable (analog mono) to connect between the receiver's sub-woofer Pre Out and the sub-woofer. This cable has a single RCA plug at each end of the cable. The cable is somewhat thicker than some audio RCA cables. You can use any RCA cable temporarily. The manual for the HT-R758 is available from Onkyo here: https://onkyousa.com/ht-r758 . The current link to the manual is https://assets.onkyo-av.com/product-manuals/HT-S6500_English_2022-11-02-204020_ivkn.pdf?v=1667421620 . See page EN-13 (page 13 of the PDF) for connecting to the subwoofer. The original package came with a 10' RCA sub-woofer cable, see page EN-1 (page 81 of the PDF) for the speaker list. I hope this helps. Cindy Wells
