Center speaker will not work

I have a Onyko HT-R540 reciever. I have no sound through the center speaker. When I run a test, all the speakers work except for the center speaker. All other speakers work well. Other than a possible defect with the reciever, is there any adjustment or setting I am over looking ?

Re: center speaker will not work

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.

Get my dish reciever, sony home theatre, and 55in sanyo tv to work together

If your TV and sound system both have a Digital Optical Out/In you can use a TOSLink cable (an optical cable) to connect your TV directly to your sound system, and remove the connection between the DISH receiver and the sound system. As long as your sound system is on the right input, all sound accompanying the picture on screen will go to your sound system. Most TVs also have an option to turn off the internal speakers, if not just reduce your volume all the way down to avoid that weird ghost sound effect. If you use your sound system all the time for volume, you can program the sound system to your DISH remote's AUX, and even set the remote so that it only sends volume and mute commands to the sound system (that way you don't have to dance between sat, tv, and aux all day, just leave it in sat mode).

To program your remote to the sound system, follow the instructions on the sheet you got with the remote (yeah, right like anyone kept that) you can use that link to program your remote. You can also use the learning mode if your remote has a little glossy square on the top left side and you have the original remote to the sound system. (Learning mode can be gleaned from the remote manual Remote Control Manuals)

After programming the aux device, and verifying that it changes the volume up, down, and mute, THEN:

Hold AUX until light blinks 3 times, hit pound (#), Volume Up, 0 (Zero), pound (#), SAT, then test to make sure it goes up and down.

Whenever a little bass sound - explosions, gunfire, helicopter blades, etc., ''PROTECTOR'' flashes on LED and shuts down receiver. Seems to happen more frequently lately. Subwoofer cable sturdy, no...

The protection feature on these units will shut off the receiver when there is too much power draw or when a speaker wire is touching another wire. First, check all of your speaker connections and make sure the wires are nicely twisted and inserted into the speaker and receiver with no stray wires touching. Secondly, if this doesn't correct the problem, try going into your speaker settings menu on your receiver and select "small" for each speaker. Let your sub handle the bass. The sub cable should have no effect on the protection feature of the receiver. The speaker wires, however, are the most common culprit of a receiver turning off (protector). Hope this helps.

Connecting an a/v receiver to a Dish network receiver

DO you have manuals for all the units listed?
If not , try the Samsung consumer site.
It would take me quite a while to figure out your situation even with manuals and I have a business to run besides.

Also, ask some questions of Tech Support at Samsung..Let them KNOW how much you spent on their stuff.

God bless,

I am using an HDMI cable on my STR-DG710 and get no sound

A lot of devices like PS3, HD DVD Players, Cable boxes, etc., require you to define on the setup menu if sound will be coming out of the HDMI cable or not. Most of these devices can be set to HDMI Auto, but not all of them do.

I currently have both my Blu-ray and HD DVD player outputting both video and sound through my HDMI into my STR-DG710. Both devices are setup to output sound through the HDMI.

But like the other person on here posted, it you have a DVI to HDMI cable, you won't be getting sound. The only device that will output sound from a DVI to HDMI are select computer graphics adapters like the GeForce 9800 GT series video cards, and even not all of those will have this feature.

Hope this helps.
