The front left and right speaker channels on my sony amp cut out a few minutes after the amp is switched on. there is a click every time it does this as if it was switching between speaker channels.the amp usually settles down after 15 to 20 minutes but it is annoying especially when using the full 5.1 surround set up.the front centre and rear channels are unaffected.will i need to have the amp serviced or is it an easily fixed problem? thanks stephen
Always check the audio cables with another set before you do anything else.
I lean toward an overhating condition since the unit does not go into protection mode right away, and then returns.
My thoughts are as follows...
1) The receiver needs better ventilation
2) The speakers are below the rated minimum nominal impedance, causing the amplifier to strain and overheat
3) There is a problem within the amplifier that is causing this problem - this is not user repairable.
I'd try another pair of speakers which are rated at 8 ohm nominal impedance and give it a trial. At the same time, monitor the heat output from the unit (note that modern amplifier sections do run hot). If the unit runs extremely hot at a low volume and still shuts down on 8 ohm speakers, it's time for service or replacement depending on value.
