Had the receiver for years, but not setup in a 5.1 configuration. I had use it mainly in 2 channel or Left Right and Center Channels.
Finally got the rest of the speakers and cabling in place and discovered the center channel no longer worked. Didn't worry too much about it because everything else worked and I just redistributed the center channel to the L and R fronts.
A few months later I installed a sub. All sounded great for a week or two. However, now I get no sound from the surrounds as well. Sub and fronts sound great.
Could I have blown a fuse or something else? Any other ideas? I do plan on replacing the unit, but was hoping it would last another 6 months to a year. If it needs to be repaired, then I might as well just get a new one.
Any advice or help is greatly appreciated!
Thanks!!

They apparently work today. Though I cannot explain why. When they failed, I tested using the receiver's test tones as well as the DVD's THX Optimizer.
Center channel is still inop. Any additional thoughts as to what this might be? Should I still have it looked at?
Thanks!

Re:
Even if it were a fuse, a blown fuse is merely a symptom not the solution.
From the symptoms you've described the AMPs are the most likely problem. They are mounted to a large aluminum heat sink usually about center of the main board. There are several and they are a task to remove and replace because the entire board has to be removed...
However, it's not too costly a repair and for a qualified shop something that can be done in a couple of hours - including testing.
If you like the receiver get it fixed. Compared to most digital receivers today it's probably cheaper to fix this one than buy another. And a good repair shop will add years more life to that unit...
Hope this helps.

If it's not working one minute and working the next it could only be one thing - poor solder joints on the components we discussed... If you can get to the bottom of the main board that would be too difficult for you to spot yourself... And if you're handy enough with a solder gun touch them up yourself by reflowing some new solder over the connections..

The signal that comes from most tv's via the optical output is a stereo signal only. That is what your receiver is reading. You would have to manually set your receiver to decode the signal into surround,.
You have to configure it first. Make sure you follow the instructions on page 5 of your manual to run Auto MCACC Setup which tests the acoustics of your room, speaker size, power level, etc. This is necessary before it will enable you to use surround sound.
Assuming that you mean Dolby digital 5.1, confirm that you have a center channel properly connected and perform the following;
Using the remote, enter the menu on the receiver and navigate to the selection labeled "LEVEL." Toggle through the selections until you reach the "CENTER CHANNEL". You will be able to use the remote to increase the volume of that channel in .5dB increments.
There are a few things required for the rear surround channels to operate;
1. The surround back channels must be enabled in the surround setup menu.
2. The media being played through the receiver must have audio encoded for the rear surround channels. There are only a few exceptions to this but I'll exclude the explanation for simplicity.
3. The audio level of the speaker channels must be set high enough to be audible.
Enter the surround setup menu with your remote. Use the center button on the remote to toggle through the selections, press down on it to enter the selection. You will navigate to a selection in the surround setup menu that says "surround back" or S/B with a selectable yes or no indication. Press on the center button to enable them.
Media like DVD or Blu-ray that has 6.1 or 7.1 channel audio has separate, or often referred to as "discrete" or "matrixed" audio intended for playback through surround rear speakers, depending on the music or movie. If your media is encoded for 5.1, then there will be no audio sent to these speakers. However, with the different modes of on-board digital processing of this receiver you can still have audio through these speakers.
Last but not least is the actual playing level of these rear surround channels. They may simply be adjusted to quietly. Enter the setup menu with remote, choose "level" and navigate to the rear surround channels. You can adjust the level up or down in 1/2 dB level increments by toggling left or right with the center button. Each surround channel can and should be adjusted independently and equally.
Yes. It is 5.1 surround. There are 2 front channels, 1 center channel, and 2 rear channels which comprise the "5" in 5.1 surround. The pre-amp output channel for a sub is the ".5".
I had this problem too. Finally, after using the MCACC setup and making sure all the speakers worked, I found I had to set the source to FM, TV or whatever from the remote control and set the mode to advanced surround sound using the front panal button on the upper right. Had to fool with them a lot. Good luck.
Thanks for the quick response!
Looks like I'll be getting it repaired!
