Most likley it is in need of repair. I suspect the output IC. Check for bad solder connections on the IC and voltage regulators.
Remove the speakers and see if it still happens (it probably will).

HOW CAN I CONNECT A MIXER TO A TECHNICS SA-DX940 AV


I used the manual downloaded from http://www.manuals365.com/technics/sadx940.html

Try using the final stereo output of the mixer as the input to the CD or Tape or VCR inputs.and use the switches on the fromt of the DX940 as necessary.
The specificatios state input sensitivity is 27 mY so your mixer needs a low output..
No reason it shouldn't work.
