Technics Audio Players & Recorders - Recent Questions, Troubleshooting & Support


I was struggling with the same problem with my friend piano. You need to replace check module which is plugged near power transistors. I found two bad transistors g109 and q119 (2SA1015). Changing those transistors and remaking soldering joints solved this problem.

This is hard to diagnose without special equipment. At the very least you need an OHM meter to test the speakers to see if they are ok. Beyond that you can use headphones to see if there is audio output. Other than that you need an oscilloscope or other visual diagnostic gear to check the amplifier.

Make sure your speakers and speaker wiring is the correct impedance and not shorting. Ensure there is plenty of clean fresh cool air for the amplifier.

Disconnect all speaker wires from the back of the receiver and turn it back on. If overload does not turn on, post a comment and I can walk you thru troubleshooting. If it does, your receiver needs to be serviced. Hope this helps

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.

hello it sound like the output ic may be in trouble you may have just dry joint on the ic which just resolder it . or there could be a capacitor leaking or they may have swelled up in which you will have to replace. it's best to do some visual checks first i'e look for any burnt parts any capacitor with bulging tops

Be sure that the EQ settings aren't accidentally putting you over the top as far as demand is concerned. Bass-heavy material? Same conditions apply...accordianman

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.
