Right channel is completely gone

The receiver's out put sections are grouped in pairs. Front left and right in one output, rear left and right in second output, and center channel and sub output on the third. Sounds like a semiconductor or semiconductors have gone bad in the center & sub output.

go to audio set up and configure the system for 5.1 or higher sound output.then only all the speakers ll work

there are 2 channel modes on your reciever, as well as surround modes, and it sounds like you have changed modes by accident. just open the little door on the front, and take it out of 2 channel mode

Hi names Rui i like to help you by giving you step by step instruction in propely hocking up your logitech speakers:

Instructions

1. Connect the black plug of the rear right speaker into the black plug on the subwoofer.

2. Connect the yellow plug on the rear left speaker into the yellow input on the subwoofer.

3. Connect the red plug of the front center speaker into the red input on the subwoofer.

4. Connect the white plug of the front left speaker into the white input on the subwoofer.

5. Connect the d-sub connector plug from the front right speaker into the d-plug connector on the subwoofer.

6. Connect the green, black and orange input to the matching plugs on your computer. If you have a four-channel sound card, connect the green plug from the input audio cable to the front plug of the card and the black plug to the rear plug. Do not connect the orange input. If you are using a two-channel sound card, connect the green plug from the input audio cable to the "Line Out" jack on the sound card. Do not connect the green and orange plug.

7. Plug the subwoofer power chord into the electrical power outlet.

8. Place your subwoofer on ground around your computer desk. Position the front center speaker on top of your computer monitor.

9. Place the left and right front speakers on the sides of the monitor. Position the left and right rear speakers behind you, making sure they are pointing toward the front left and right speakers.

10. needs to support 5.1 surround. Normally, more than three sockets for sound indicates that it does. Then you need to use the software that comes with the sound hardware to configure it for 5.1 - Default will be 2.1 or just 2.
Check the control panel out. This is a lot easier under Windows 7.- Here you can access what you need via the speaker icon on the system tray (right click)
There is NO problem with your OS or hardware, this is pretty standard...

hope this will help you solve your problem.

your main 2 speakers (front left & right)..hopefully the 5th speaker is a subwoofer right if not it will be...the last 2 speakers will be use as the rear (left & right)...in order for this to sound correct the receiver should have a button (5:1) depressed ...otherwise you just have 5 regular speakers...

Can you explain about your system problem in detail.
So that it will easy for us to offer you better solution.

Hi, first of all did you verify with the manual if it is possible to run a testsignal through all 5 channels?
One of the most common problems in this case is the basic settings of the device. If you don't have the manual, mostly you can download them from manufacturers website. Chances are that for some reason the setting is set 3.0 stereo (also known as 3channel sound) which is always the 2 fronts and the centre speaker.

Best thing to do it is take a DVD with THX on it and run the THX setup, it will send test signal to all channels.

Check your speaker connections it sounds like you have a 5.1 or higher sound system. 5.1 means left front speaker, right front speaker, center speaker, right rear speaker, left rear speaker and subwoofer.

Voices in movies all get channeled to the center speaker (you can usually hear it a bit from the right and left front speakers as well). If your center speaker is disconnected or not working, you will only hear the background sounds.

You need to use a digital interface cable between the sound card and the speakers to get all of the 6 channels to work properly.
