Onkyo Receiver shuts down when volume set higher.

Though you have not given us the make and model number of that I receiver if it is turning off when you power it up and turn the volume up this usually indicates a problem with the internal amplifier it most likely is damaged

Hi Ryan, 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.

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.

does it turn off and then back on repeatedly at higher volumes? if you back the bass off will it allow you to turn it higher? if so i would think your impedance is off causing the amp to overheat or the power requirements for your speakers are way higher than your amp can produce

HI check your speaker cables are not touching, also make sure "b" speakers are not on and that all your speakers are 4ohm or higher as this will cause the amp to shut down if they are to low an impedeance,The amp is protecting itself when it shuts down.

hope this helps.

Channel level output can be adjusted in the menu if you have the remote. Set the rear channel level volume higher and the fronts lower if need be, and then turn up the volume. Enjoy!

i have the same problem with a onkyo tx ds494

I had this same problem and it turned out to be a twisted kink in the speaker wire. Run a sound check to each speaker separately (from your receiver menu) and turn each one up until the receiver shuts off. Check the wire to the speaker that caused it to shut off and make sure the +- ends are not touching each other at either end, and that there are no twists or kinks along the way.

The overload board is failing.
