Sound issue It sounds like only one speaker works at a time, when you switch connections the problem switches speakers. It seems to come on and off of the speakers, i checked all the settings, and there should be an even distribution of sound. But, only one speaker seems to work at a time. Now my screen went black, and I only have audio, no visual. Could these be related? I checked the forums and I am having the kit come to my house, so that should fix that issue. But, I won't know if the one speaker at a time will be fixed by it too.

Check the speakers if they work. Connect the speaker terminals using a short wire to a 1.5 volt battery (AA or any dry cell batter) and listen if there's a thumping sound when the wires are connected to the battery terminals. If there's no sound, your speakers are busted. If there's a sound, check if the wires are okay. Use the same method with the battery with the wires from the back of your stereo. Make a small cut on the wire and attach the short wires you used earlier.

Many devices will automatically switch off the large speaker when ear phones are plugged into them. Also there may be a switch or button or prompt on your radio to switch between regular speaker and ear phone jack. Look for that first.
Try connecting and disconnection ear phones while listening to a station and see if the problem is intermittent. If is works sometimes but not every time then it is most likely an internal connection.
You will have to access the inside of the radio to investigate further. Connect a working external music or sound source with speaker wire to the terminals inside the radio that connect to the radio's speaker. If the radio's speaker works with the external sound source then you know it is a bad connection inside your radio. If the radio's speaker does not work with the external sound source then it is most likely a faulty radio speaker. Look closely for a broken solder point or broken/disconnected wire.

Some stereo system have the ability to switch off the speakers when playing via headphones. In others the headphone socket itself does the switching. However headphone sockets can become faulty and when the headphone plug is removed it doesn't restore sound to the speakers. It's very easy to fix this, with a check that the contacts are not bent out of place. Or you can rewire a new headphone socket, making a note of the wire connections before you replace it.
Sometimes it is quite difficult to get the speaker cable to make a good contact with the speaker sockets. You should check that they are making contact.
To test any loudspeaker just connect a 1.5 battery for a short time across the disconnected speaker. If working the speaker will pop!
As the sound is going to the headphones the amp seems to be OK and one of the above options should correct the problem.

Negitave, the problem is your receiver. Speakers only work when there's enough sound being amplified. Your receiver is what powers out the sound. Open it up and check for loose connections. Even cleaning it out sometimes helps.

I think ur sound driver not properly installed plz reinstall again properly .

Did you try switching Speakers A and Speakers B button on the AV receiver?

I think you have a defective device there. RMA!

contacted a local service dealer

don't switch to stereo mode. switch to prologic mode

your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck
