Everything works except no sound from front speakers

SOURCE: Problem with Dolby Digital mode

Hi Whitesox, thanks for the suggestions! I finally got to the bottom of the problem, and it turned out to be the new Toshiba DVD player I recently purchased (model SD5000). I never had to make any adjustments to a DVD player before to make it play dolby digital signals, but this new Toshiba essentially comes with Dolby Digital diabled as its default setting. You have to go into its setup menu and switch it's digital audio mode from PCM to Bitstream. What's strange is that even with the default settings on the Toshiba it would play in DTS mode correctly.

SOURCE: RX-V596 center and rear channels do not have any sound

Nevermind... My center channel output was set to "NONE" I've had this receiver for a few years now, probably set it that way back when I got it. Oh well, Helps to re-read the user manual...

The info is in the "SET MENU" section of the manual, Pages 35-38. Should solve the issue for "almccrum" above as well.

If you don't have your manual it can be downloaded here:

I think you need a digital coaxial wire instead of the composite ones

SOURCE: Speaker output

Yes, there are relay type switches associated with those outputs. Your RX-V1 is not dying.
Just plug a pin plug in and out of the dead channel to bump the switch. You will hear the speaker
come on. If it doesn't come on,do the plug jack in an out of the pre out again. It will come on.
You can use the test tone to check all channels and rebalance volume levels. You are making the
pre out connect to its power amp. It seems the problem got better when activating those switches. Most likely a cleaning issue. You can also jump the mains and center, and there is also
a modification to jump all channels. I bought my RX-V1 very cheap because of this and love it.
Of course outboard power amp would solve all, but getting this reciever to connect to it's own
power amp has been thrilling as far as bang for the buck. I do use the front effects also, and like
them. It may seem like a pain, but it is worth it to get those channels going.

SOURCE: Sony STR-DH510 Multi-channel AV receiver

The STR directs sound to the center as instructed by its speaker setup. You say the center does not work on calibration. Is it defined?

Prove another speaker does or does not work on the center output. Then we'll know if it's the receiver or the speaker ensemble that has the problem.

Have you checked the manual for this "
There is no sound, or only a very low-level sound is heard from the center/ surround. "?
