Okay so i was working with my reciever... and was moving a speaker while it was on. the wires came out, whipped back and the music stopped. i could smell melting plastic. i quick turned the reciever OFF, but when i retrieved the wire it made a huge spark when i picked it up. is the whole thing fried? just the channel?

The rear left and right channel has a audio output ic problem, first check rear speaker wires for shorts, if okay! the system will need to be assessed for repair costs.

The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

First, unplug the stereo speaker then open the back. you see the 2 wires attached to the woofer then test it by multi tester. if it moved it means its okay. check the wires for the loosen speakers. solder it and test it.

Try to reconnect all the wires, the problem seems to be with connection. Instead of spending lot of money on speakers, you can buy just the wires, they are pretty cheap. Hope this helps.

sounds like you have blown speaker swop them over and see if it works, if so you need repair shop

i had the same problem check if any of your speakers are disconnected mine i was doing some work to it and i let the wire accidently touch a peice of metal and it would play for a bit then just stop playing music it is something to do with it heating and such

If your rec'vr worked with the original front and rear speakers, the new speakers are either defective or ar the wrong impedance.
Also, I find this confusing: "I connected the wiring for 1 of the front speakers to the connection on the rear of the receiver". This may indicate wrong wiring connection. Make sure you have connected the speakers properly

If you had the Speakers Set to A (not B) and no headphones connected when you pressed the TEST TONE button on the Onkyo HT-R540 (also known as the HTS-790) remote, and you had no sound from the Center Speaker then try the following steps. 1) Check the Center Speaker wiring at both ends under a bright light and make sure that there is not a strand of wire touching the Receiver Chassis or another speaker post. Check both + and - . If that looks okay, 2) unscrew the Center Speaker Post connections on the Receiver and verify that the bare stripped wire is making contact. Often, the insulation is too far into the connector. When screwed down, the wire's insulation is crushed and keeps the bare wire from making contact. If this looks okay and the unit is under Warranty, your last test is to: 3) temporarily swap the wires from the Center Speaker with the Right Front Speaker. Turn the volume down low and try the TEST TONE button again. If you now hear sound from the Center Speaker box itself and none from the Right Speaker box, then the Receiver is the problem. If you still do not hear sound from the Center Speaker box, then the Center speaker itself is defective.

plug your low input into the subwoofer output of your reciever.that should get the sub working then you have to run speaker wire from your speaker outputs on your reciever into your sub in the top row of inputs then the outputs on the back of sub(the bottom row of speaker hookups go out to your speakers....my email is [email protected] if you still cant get it i can talk you through it on there or ill give you my instant messenger name is you still have problems good luck,b
