Rear surround speakers quit working from my Onkyo

To set up your home theater system with the equipment you mentioned, follow these steps:

1. Connect the Onkyo receiver to the NEC TV using an HDMI cable. Make sure the HDMI input on the TV is set to the correct input for the Onkyo receiver.
2. Connect the Panasonic DVD player to the Onkyo receiver using an HDMI cable.
3. Connect the Firestick Lite to the Onkyo receiver using an HDMI cable.
4. Connect the Panasonic speakers to the Onkyo receiver using speaker wires. Make sure you connect the speakers to the correct speaker terminals on the receiver, which are usually labeled with the speaker's position (e.g. front left, front right, center, surround left, surround right).
5. Configure the Onkyo receiver to use the correct input for each device. For example, set the input to "DVD" when you want to watch a movie on the Panasonic DVD player, or set the input to "Firestick" when you want to watch content on the Firestick Lite.
6. Configure the audio settings on the Onkyo receiver to use the correct audio format for your content. For example, if you are watching a movie with Dolby Digital surround sound, make sure the receiver is set to decode Dolby Digital audio.
7. Adjust the volume and other audio settings on the Onkyo receiver as needed to optimize the sound quality.

Once you have completed these steps, you should be able to enjoy surround sound audio from your Panasonic speakers through the Onkyo receiver.

If this is a Surround Sound System you can check channel and audio tone levels using the remote. Check remote for a receiver button followed by Test button. Check manual for test instructions.

Check speaker wireing make sure all positive and negative connections are correct. What cable are you running from tv or DVD player.check to see that wireing is correct on receiver for sorround speakers. Run audysee sound calibrator set up. Make sure correct settings for sorround sound in bluray player/DVD player

I had the same issue, but apparently...it's not an issue. What I discovered is that the system was fine, but the station I was watching didn't broadcast in 5.1 surround sound. Therefore, only the front speakers will have sound. Try putting a dvd in, or listening to a gameing system through it. If you don't have sound after listening to something that puts out full surround sound, then you know you have an issue.

Some TV is not broadcast in surround... you will not get back speakers from TV, only from DVD.

Sounds like it's just in 2 channel stereo mode, only 2 speakers working out of 5 and a sub, look for a selector switch for switching to 5.1 surround, as far as the no video problem try replacing the cable for the video connection. 

Since you have the cable connected to the reciever thru the HDMI, you may have accidently changed the input source of the reciever from HDMI or digital to analog.

When you have the reciever set to listen to the cable, check the input mode and make sure it is set to use the HDMI or digital input and not the analog.
The rca jacks are analog, and they worked, so I think you have just solved your own problem without realizing it.

Let me know if this works and if so a good rating would be appreciated. Thanks and have a great day

YOU ARE PROBABLY USING 5 SPEAKERS WITH OR WITHOUT A SUB, AND YOU CONNECTED THE REAR SPEAKERS TO THE REAR SPEAKER OUTPUTS. THEY WON'T WORK THIS WAY. RECONNECT THE REARS TO THE SURROUND SOUND SIDE SPEAKERS, AND RERUN THE AUDISY SETUP. THIS SHOULD TAKE CARE OF THE PROBLEM. YOU HAVE TO FOLLOW THE DIRECTIONS AND SET UP THE DVD INPUT, IT WON'T WORK RIGHT OUT OF THE BOX, TOO MANY VARIABLES.

I CAN'T GET MY 875 TO RECOGNIZE COMPONENT VIDEO SIGNALS, I GUESS I'M STUCK USING HDMI, AND COMPOSIT INPUTS.

Hi
I have the same tv but my dvd surround is a toshiba, that shouldn't matter though. When I watch a dvd I go to component 2 which is where I have my dvd connected on the input of the tv when I watch tv and want the surround on I go to component 1 which is the tv input then on my dvd player I go to auxillary and I can watch tv in surround. I don't know the LG home theatre system but you should be able to select your inputs like between dvd, tuner, aux. Flip between them and you should get sound. hope this helps.

Did you try to connect AUDIO OUT from your TV to AUDIO IN on your package?
