It doesn't have a tape loop, thus no way to hook it up for all sources. Of course you can still use it inline for one of your sources.

Hello, I am sorry about your issue. I f the receiver does not stay on with nothing connected it would need to be serviced. Thank you, Onkyo USA

Hello, I am sorry about your issue. Your hook up should have nothing to do with the remote. You should get some functions like on/off, volume control. Thank you, Onkyo, USA

Pull the batteries out from the remote control, and leave it out until step-4 Press and release each and every button, one at a time on the remote control, until every button has been pressed and released at least once. If the remote control have slide switches; move the switch to each position, then repeat the button pushing as in step-2. {When you've done, be sure to put the slide switch in the correct position to operate the unit the remote came with.} Put the batteries back. Try the remote. If it do not help you: Check the remote control for its infrared emission. Check it with fresh batteries. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it.

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.

Did you try to ask this question on the support forum from Onkyo? because I don't know what you mean with reset. When a device is defect, there is no reset button, to repair it. Only what software is involved or settings in a memory that can lose settings when the power is down, can be "reset" Onkyo USA Support Forum Index page

I think your receiver is damaged. Try this. Mark the speaker wires on the back of the receiver. label the speaker connected to the left channel "Left" and the speaker connected the the right channel "Right" Also pay attention to the polarity (positive an negative) making some type of marking on your speaker wire so you can reconnect them correctly. Disconnect both left and right speakers. Connect the speaker wire that is labeled "Right" to the receiver's left speaker connections only then turn your receiver on. IF the loud noise comes back, this speaker is damaged. I am guessing that the speaker is fine. Now connect the speaker that was labeled "Left" to the receiver's right speaker connections and turn the receiver on. IF the loud noise comes back like it did before but now playing through the "good" speaker there is a problem with your receiver. If so, your receiver is 10 years old. Isn't it time for an upgrade? Try ebay for good used equipment deals.

I ran into the same issue with my Onkyo 787 receiver that the internal settings would get reset after a short power off. Getting all settings entered again (preferences, speaker distances, volumes, stations, etc.) is a real pain. Good news is that Onkyo DOES have a battery (actually a capacitor) to store the settings and that capacitor can go bad. Another good news is that replacement is quite easy.The settings are preserved by a 5.5V 0.1F capacitor. Digikey sells it for around $1.50, you may choose a higher capacitance, as 0.3F if you're replacing it. I didn't want to wait for the part, so I decided to replace with something I had around from an old power supply. I used 10V 1000uF capacitor as a replacement and it works fine. Yes, it is 100x less in capacitance, but preserving setting for a short time is better than not preserving them at all. Settings survived a couple of days disconnect and I haven't tried leaving the receiver off for any longer yet. Here's how you can find it: it's on the main horizontal board, on the same side where the volume control is. It's small, looks like a watch battery turned on the edge. Mine was in a blue shrink wrap. I cut off the leads next to the battery and left the wires sticking out of the PCB. There's plenty of room to put any capacitor.Pixonian

yes there is ,,, it is located on the same board that has 3 fuses on it, you will have to unplug the unit before disassembly, and remove the top cove and bottow covers,,,, you will have to de-solder a small battery pack surrounded by either blue or yellow heat shrink,,, please not the polarity before removal, as putting it in wrong will cause a non- memory retaining situation to continue...I hope this helps

Turn the amplifier on.Go to audio menu select sub-woofer mode to on position.It should solve the problem
