My Sony V555ES when in surround sound mode all but eliminates the voice track. Sound can be heard from center channel but back ground noise and very very week voice track.
Also recently it has started to kick itself off (thinking a surge protection) when loud noise such as gunshot is in the track. This is at what I would call moderate volume levels below what used to be ok on this receiver. Turning off/on resets.
I'm debating taking in for repair or replacing this unit

Re: Audio Video Receiver Problems
It sounds like the center channel isn't plugged into the correct speaker output. Unhook the speakers and reattach them while paying VERY close attention to which jacks you're putting them in. Report back with results.

Sometimes these units have the ability to switch the speaker off and on. Look up the speaker settings in the manual.
As each channel in the unit will be separately driven the power amp for the center channel could have failed, but I think it's unlikely unless you have had problems with the sound on it before, or connected it wrongly causing a fault.
Voice tracks are usually routed to the center channel. You don't mention having a center channel speaker hooked up. If this is the case, then you need to go into the receivers setup menu and set it for no center. This will reroute the voice tracks to your front speakers.
If you have checked the speaker and wiring. Check the setup, the center channel could be off or it's not in a surround mode.
When playing a DVD through the receiver are the voices heard clearly in the front speakers? if so the center channel is turned off.
The dvd player is responsible for reading the surround sound track, and sending it to the receiver. First make sure you are playing the surround sound track on the dvd, many have a stereo track too. Next, try another dvd and see if you can play surround sound on that one. If you can't play surround on ANY dvd I would start looking at the audio connection from dvd to receiver. Are you using an optical cable? Red, white, and yellow RCA cables? Optical will transmit any sound over only one cable, RCA cables need one cable for each channel (LF, C, RF, LR, RR, sub.) If your connections are correct, is the receiver set to play a surround sound track? Is it set in 2 channel mode?
Can I assume the calibration procedure also didn't work for the Front left channel? (It's not a "surround" if it's in the front). Switch the receiver to Stereo mode to eliminate any DSP actions. Tune an FM station to eliminate any external device or cable issues. What do you hear from the two Front speakers?
OK? Select a DSP surround mode. Check all modes. What happens?
If the channel goes dead using some or all DSP modes there's probably something wrong with the processor. If they all work...
Isolate the source that exhibits the problem.
It was a bad left channel cable somewhere, wasn't it?
Try setting your amp to "auto format decode".
It should easily be heard in this mode.
The sub will not show up on the display when in 5.1 mode. (Blue light on)
Use this with music, and use the 5.1 with movies to get a better experience from your amp.
The sub will work in 5.1 but doesn't show up in the display. Try movies with loud sounds.
Most of the pre-set sound fields are of no use to me. I only use normal surround, and AFD and love it. I hope this works for you!
