20 Most Recent Technics SA-EX320 Receiver Questions & Answers

Disconnect the speaker wires at the receiver, turn up the volume, if it goes into protection, it's an internal problem and needs service. If it does not go into protection, re connect one speaker at a time and test. If it shuts down check the speaker itself, if they are as old as the receiver, chances are good that the surrounds on the speakers themselves have disintegrated. Older speakers used foam surrounds, newer ones use rubber or plastic composite material that will not disintegrate. What will happen is dust and moisture will get into the voice coil and cause a short, even though the speaker still plays. Hope this helps. If you need more help or just advice, post a comment, and I'll help if I can

I would guess that the switching chip is faulty inside the receiver. Since the CD works OK, the amplifier section and pre-amp section are good. What you are hearing with the others is crosstalk. This chip shouldn't be more than about $10-$15. Add in the local labor rate for the total repair cost. I think that the chip for your model is a TC9163.

This posting is very old but the answers unhelpful so I thought I'd chime in. I have the same receiver and there is not mute button on the front panel, nor does the volume do anything. Put it on, select the tape or other aux. input. Press and hold the Phono button for several seconds and the mute light should go off and the volume get much louder.

Go down to Walmart and get CD Cleaning Disc. They have little brushes that clean the optics.

Or it is a counterfeit copied disc and has become corrupt!

Try the discs on another unit.
