Sony DAV-IS50 stuck in one sound mode!!!!
Ok, I'm new to the forum but not new to 'what hifi' and have been reading it for several years now.
We have the above system in our lounge and it has been working fine until recently I noticed that the sound was the same from every speaker except the centre speaker which is outputting no sound at all.
I have been through all the settings including the test tone at which point the centre emits the test tone so the speaker must be connected propperly and the amp channel not blown.
Regardless of what surround mode I put it in the sound is the same from all the speakers with the exception of the stereo mode.
Any ideas what this could be? I've tried re-callibrating and swtiching the unit off from the mains for about an hour.
It's the same regardless of whether its a DVD or the television.
