Question about Yamaha HTR-5790 Receiver

"Check Speaker Wire" error on my Yamaha Receiver

Whenever I attempt to watch a movie or TV in any type of surround sound, the receiver makes a clicking sound and then shuts off. When you turn it back on it gives you the "Check Speaker Wire" error. I have checked all of my connections of the wire to the receiver and all of the connections to the speakers. Nothing is touching and the wires aren't even exposed. I made sure the impedence is set at 8 ohms and ran all of the various troubleshooting tips in the back of the user manual. IT works fine when in the "straight" mode, but will shut off if switched to any of the surround modes. It also works fine when the Xbox 360 is playing trough it, but the sound is only running the the front L and R channels. I have tried with A on and B off, B on and A off, and both off. Ultimately the result is always a little clicking sound with a shut off, followed by "Check Speaker Wire" error. I reset the receiver to the original factory settings, also with no positive result. This is a new receiver and worked just fine for the first month or two, and then just randomly started shutting off in surround mode. I am out of ideas, so any help or solutions you might have would be appreciated.

    Goday. I have been having problems with my receiver for some time it shuts down when watching a movie.I purchace a new one a Yahama HTR-5940. It started doing the same thing,after trying a new speaker swaping out one at a time. I found I had a defective speaker.

    Once that was repaired about two months it started again, this time a broken speaker wire was at fault.Afer about two months it started AGAIN.

    I found out it was my DVD player was not set to Dobly Digital in 5:1 mode.

    Once this was done I watch the last Star wars as loud as possible.It worked like a charm.

    Then I was watching the Movie 300 it worked justed fine for the first hour.

    Then it quit again and it comes up with check speaker wire error.I have purchase the best wire money can buy and the polarty is correct.

    I am out of ideas.

    Any help would be great!

    I have the same problem with my 5790 and have disconnected all the wires except the power in. I turn the unit on and it goes into standby mode in about 5 seconds. I got the unit to stay on by hitting the a/b/c/d/e button on the front panel at the same time as the tuner up button to the right before I hit the power on button.

    All the stuff that comes up on the display has no meaning to me so I am stuck.

    Having the same problem here only everything worked fine for 5 or 6 years. I guess I have to go through and systematicall disconnect every speaker from the system and hope I find an offending one. Otherwise is it safe to assume that the receiver has just gone bad?

    I have the same issue with an HTR-5830. No idea what to do. It just gives that 'check sp wires' and shuts off. Some of the speaker connections don't even work initially, either. I've changed up the wires, tried speakers one by one--nothing

Found the source of the problem with "Check SP Wires"! to solve it is necessary to check each speaker connected to the device Yamaha on the rear panel (red and black) using the device for determining the number of ohms, which shall not be less than 4 ohms, in large passive speakers experienced in Amfitone AU-027, the result showed that left at 0.45 (7) ohms, and the right-hand column, as such, no.
The successful test ... and good music!

Hello, I just bought HTR 6080 and I'm having same problem. When I turn up the volume, receiver will shut off by itself. When I turn it back on "Check SP Wire" message is displayed on receiver front panel. I tried eliminating one speaker at a time and tried two front main speaker only. Yes, did check speaker setting to 8OHM and I tried to program receiver in "Auto Setup" mode. While receiver setting itself in "Auto Setup" mode, it will shut off by itself. I remember I had old receiver and it had same problem. I did swap it at the store but still same problem. I have no idea what could I be doing wrong. As other mentioned, I have checked speaker wires OHMs, nothing I can find wrong with setup or hardware. I'm going to call Yamaha technical support if I can find there phone number. Think is getting me mad, and if this is not resolved soon I going with Harman Kardon.

You risk to crash a set of speakers. In any case this will have a detrimental effect on the sound

SOURCE: can I mix 6 and 8 ohm speakers?

Most Yamaha HTR's are high current receivers so setting the receiver to 8 ohms and running the 6 ohm speakers shouldn't be a huge problem. I wouldn't crank the volume though if i were you but at a decent level you should be fine.

Denon receiver not working surround output

If everything is connected correct, the only thing I can think of, is you don't put in a surround signal. If you only feed 2 way stereo, only two speaker will work. Also if you switch to stereo, the other channels will stop working. Check the cables, the settings and the input.

I have a JVC TH-S3 surround sound system and would like to know if I can l watch television in surround sound as i can watch dvd's and listen to the radio in surround sound. thanks

Yes you can get simulated 5.1 surround sound from your TV as well as radio. Just switch the JVC surround mode to Pro Logic II movies or music In some systems it will display only PLII.
Just connect the TV audio out to the JVC Aux input at the back ( red and white sockets ).

I have an older model Yamaha HTR 5830 receiver and I want to set it up for surround sound (5.1). When I test the receiver all five speakers give back a signal, but nothing ever comes out of the center or...

The broadcaster of the TV station has to tell you they are transmitting surround sound - sometimes they are just transmitting stereo. Also, the media as in CD's and DVD movies must have surround sound embedded or recorded on it to allow surround sound.

I would like to know if my ht 3913 will work thru the TV sound, I have no problem with it working when I'm using the DVD player to watch movies, but I would like to hear the TV thru surround sound

Directly , no, since the tv sound is always just on 2 channels. But you can convert it in the receiver to surround by activating either the SRS Surround or the DolbyProLogicII options on your receiver.

When watching a DVD, if i choose the Dolby ProLogic IIX Movie sound mode, the receiver powers off completely whenever a loud scene occurs. During slower and quieter dialog scenes it is fine, but the moment...

The Troubleshooting section of the manual starts with some suggestions. Check your speaker imoedance settings and make sure you're not presenting too LOW an impedance to the amplifiers.

The manual says the Dolby Pro Logic IIX mode would not be available if "SB L/R SP" is set to "NONE", which it should be if you're set up for 5.1 instead of 7.1. It's not clear what happens if you have the Surround Back speakers defined but not connected. Probably no harm but the receiver is likely trying to channel some information to non-existent speakers.

Since there's a parametric equalizer built in I'd check to make sure it's not set for bizarre boost in the bass.

The more bells and buzzers they provide for adjustment, the more opportunities for MALadjustment.

Just a wild guess. Are you over-taxing the wall outlets or power source feeding everything; or do you have excessive draw on the receiver's convenience outlets? 100 watts maximum is allowed between them.

RX-V665 Yamaha reciever has been working great. Use it for surround sound and outside, zone two speakers. Recently started turning off during movies. I run blu-ray through receiver. When playing Star Wars...

You may find a solution by doing some of the things I have tried - see below

I recently puchased this model to replace an older Yamaha system that also had this shut-off problem. The new RX665 system has the same problem but I check the impedance setting using the instruction in the manaul anyway. The problem persists. I have check all speaker wire to make sure nothing was touching. I did find one wire touching on the center speaker but the problem persist.

Since the problem followed me when I moved and with a new amp, I am beginning to think I am have a speaker that's causing this - maybe the sub.

Yamaha RX-V365 unable to receive 5.1 audio from TV with HDMI

If you're expecting multichannel sound FROM THE TV instead of from the source you're watching, it's not gonna happen. TV's are notoriously poor sound sources. This one is no different.

Multichannel TV-related audio is best found at its source - cable / sat / dvd / bd....

I run video-related audio from my video sources directly to my TV and their audio directly to my receiver. Specialization yields best results.

I'd recommend skipping the Receiver for video, too, as it adds a lot of opportunity for HDMI-related incompatibilities and sound syncing problems. The more interconnects in the path, the more distorted it will become and the more opportunities for problems. Plus you can bypass the receiver and listen to lo-fi programming like news and weather through the TV's speakers if you like. Save a buck on electricity.

Just curious, which HDMI on the receiver is connected to your TV? Input or Output?

This note is on Page 11 of the manual:

Audio signals input at the HDMI jack are not output from any speaker terminals but output from the connected video monitor. To enjoy the sound from speakers connected to this unit,
-- make an analog or digital connection besides the HDMI connection (see page 13).
-- mute the volume on the connected video monitor

"Check SP cable." -- The unit is perceiving a short circuit. Are your speaker impedances sufficiently high? Disconnect the Front Right speaker and try raising the volume again. The speaker may be blown or the cable shorting.
