Insignia receiver powers up then immediately shuts down

Hi Joseph,

It could be that there is a frayed speaker wire touching the back of the receiver and when playing at a low level the speakers do not require that much power, however when the level from the speakers increases more power is required and if there is a frayed speaker wire touching the back of the receiver there could be a short causing the receiver to shut down. A way to avoid the frayed wire is to use "Banana Connectors" that the speaker wires goes to and the connector will plug into the speaker posts. Please try the following to see where the issue is coming from. Have the receiver turned off, make sure all the speaker wires are labeled, and disconnect them from the speaker terminals. Turn the receiver on select a source that would give you sound if the speakers where still connected and turn the volume all the way up. If the receiver shuts down than it would need to go to a service center as it is an internal problem with it. If the receiver does not shut down, turn the volume down, shut the receiver off and connect one speaker and than turn the receiver on selecting the same source as before and raising the volume up. If the receiver shuts down, remove that speaker from the post and connect it to another speaker post to determine if it is the receiver or the speaker itself that is giving you the problem. If the receiver should shut down after moving that speaker you know it is a problem with the speaker or the wiring. If the receiver does not shut down, turn the volume down, shut the receiver off and connect another speaker followed by doing the previous test procedure. Keep adding speakers until you have them all reconnected to the receiver as long as it has not shut off while trying the test procedure. After determining whether it is the speakers or the receiver you would need to bring either to a service center to be repaired. To locate an authorized independent service center, check the dealer and service locator at our website: www.onkyousa.com or www.integrahometheater.com.

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.

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

If it's not happening when your speakers are disconnected, your problem is not in the receiver, it's either a wire touching at the terminals on the rear of the receiver, or a bad voice coil or crossover in your speaker. If you re connect the speakers and it immediately cuts out, disconnect all speakers and reconnect one by one testing the receiver each time until your receiver shuts off or remains on with all wires connected and you've fixed the problem. If it cuts out, disconnect the problem speaker at the speaker and test again. If it stays on, problem is in the speaker, if it still cuts out, problem is in the wire. Hope this helps. If you need further help, post a comment and I can help you troubleshoot some more.

Hi....

It's usually a component failure in the power amp section.
There are good tech shops in Cailfornia

check your speaker wires make sure none are touching each other this will cause a short and shut the reciever down

had the same problem... turns out the copper on my red and black speaker wire (on the speaker, not receiver end) was touching - causing my receiver to go to standby (self-preservation probably lol). i pulled the wires further apart so the copper ends weren't touching and that solved it.

Check the impedance ratings of your speakers. Sherwood, the actual manufacturer of the NS-R2000 receiver, suggests that you use speakers with an eight ohm impedance if you have only one pair attached. If you have two pairs of speakers attached, the impedance rating of each pair should be sixteen ohms.

This is because Sherwood wired the receiver such that an additional pair of speakers is placed in a parallel circuit to the first set. When this is done, the impedance (resistance) of the load seen by the amplifier drops. As resistance drops, you get closer to a short circuit (no appreciable resistance).

Many other receivers wire the speakers in series, which causes the impedance to go up.

Personal experience seems to suggest that the amplifier is OK with a four ohm load on it. It does run warmer with a four ohm load, which is what you'd expect. It's when you have multiple sets of four ohm rated speakers that you will get into trouble, as this means the receiver only sees a two ohm load. This will cause overheating and shutdown.

At this point the power transistors in the amplifier may have been damaged. It may require repair. Fortunately, replacement parts are readily available (though not from Sherwood or Insignia). If it continues to shut down, stop using it. You could end up burning out your speakers.

Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck

This maybe an easy one. Have you unhooked all the wires going in to the stereo. "SP wires" means you have wires to the speakers are touching and the stereo is shutting down to avoid overloading. Hope this helps...
