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

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.

Likely a power surge hit your house while away. This happens when power turns back on or lightning hits close to your house. If insured, call insurance company about it. You may be covered for replacement or have deductible applied. Small appliances like this are most susceptible to power surge. There is not enough protection designed in.. The best protection is surge module on main breaker panel or buy a protected power strip to protect high value electronics.

although power surge can trigger activations of protection circuits,

there are at times, damage is done before it is activated.

• Check first for low power supply regulators,

then check for possible output stage failure.

let me know if you need further assistance!

"Safety" mode - literally? I don't see that anywhere in the manual.

Speaker Connection Precautions

(North American and Taiwan models) You can connect speakers with an impedance of between 6 and 16 ohms. If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in amp protection circuit may be activated.

The 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 set the volume to maximum. If the AV receiver stays on, set the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact your Onkyo dealer.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

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.

If you have a Home Theater Line conditioner on this receiver, not a power surge protector, even a "Monster" surge suppressor, your problem Is AC related. For troubleshooting; first if your AC power cord is three pronged, go to Lowes, Home Depot, etc. and get a three prong to two prong adapter. Your problem is a "Ground" issue, however it may not be from the receiver, it could be "Anything else" in your home. Even an actual outlet with a loose wire. It can be very very time consuming to "hunt down". An adapter will take the rest of the house out of the picture. Disconnect all other input sources like Cable, DVD, etc. then turn the unit back on. If you still have a humm, yes the problem is internal and needs serviced. If it stops, re-connect one item at a time until the noise re-appears and you have your culpret. If you don't have a line conditioning noise eliminating Theater surge protection unit; Get one! best few hundred bucks you could ever spend. It will protect all your electronics and could save you thousands! Panamax, Furman, Monster, are your top 3. If you still have issues, post a comment and I can help you further. Hope this helps.

The most likely problem is shorted output transistors. This is a straightfoward repair for any shop that works on audio gear. Expect a parts cost in the $40-$50 range.

Try pulling the plug out of the wall for 5 min or more,give the unit a chance to reset.Hopefully you didn't get a power surge that might have blown the protection circuits.

my speakers call creative on my computer wont work they use to,i hear sound but not audible
