Yamaha Receiver Help!

[TexasTrader]

I appreciate anyone taking the time to help- I'm stumped!

I am using a Yamaha HTR-5960 receiver with a 5.0 setup (no sub currently installed). Every time I turn it remotely high it shuts off and the "check speaker wires" alert goes off. I removed each speaker one by one to try to narrow down the problem and have come to the conclusion that it must be the actual back left speaker port on the receiver, here's why:

- Receiver only turns off when a speaker is plugged into the back left port. Remove speaker from black left- no failures at any volume.
- Plugged the original back left speaker into the back right terminal (without any speakers being plugged in to the back left terminal) and no failure occurred.
- Plugged the original back right speaker (that was working) into the back left port and the system failed.

At this point I concluded it wasn't the actual speakers causing the problem, but the setup of the back left.

- To make sure there wasn't a fault in the speaker wire I replaced it completely. Tried both back speakers in the back left port and the system failed both times.


I'm not incredibly knowledgeable when it comes to electronics, but with this trial/error, I have concluded it must be the actual receiver port causing the problem. Does anyone agree, and if so- how would I go about fixing this?

Thanks!!!!!!

What type of speakers are you using? According to the manual, if your speakers are rated for 4 or 6 ohm impedance, you have to adjust your receiver settings accordingly (page 30 of the manual I found online).

Thanks for the suggestion Chad. I actually thought that might be the problem at first also and used the manual to set the correct impedance (or so I think). I also ran the "auto setup" feature of the receiver which uses a microphone to ping each speaker and adjust the settings itself.

Anyhow, based on the fact that only the specific back left port being plugged in results in failure, wouldn't that mean that its not an impedance issue? I would think if it were impedance causing the problem, it would shut off under multiple scenarios. I could be wrong though....

Sounds like something may be wrong with the amp. Problem is there's almost no way to troubleshoot modern electronics.

i had that happen to me twice with an older yamaha receiver like 8 or so years ago. it was under the best buy warranty still and they fixed it for me both times. i believe it was just something shorting out inside that had to be replaced, but i don't remember exactly what they told me.

Disconnect the unit from the power source, take the cover off and have a look around. Use a vacuum or compressed air to remove dirt and dust.

make sure you have all wires correctly poled. I've gotten cross wired occasionally.

for speaker wire all it does is make it sound off, it would not cause a short.


op take it into a repair shop.

Yea I checked to make sure it was poled correctly. I also tried finding a quality repair shop around me with no luck so I was hoping to get it done myself.

I'll try the unplugging/dust removal method to see if that helps.

thing is if there is internal short, it should kick in protection with no speaker wires attached to it.
