Question about Technics SA-DX940

1 Answer

Technics SA-DX940 My Technics SA-DX940 receiver would operate for about 20minutes and then overheat and shut-off. It restarts fine after it has cooled off after a period of no use. When I press the "HELP" button, the following message is displayed: "HIGH TEMPERATURE --- REDUCE VOLUME". The cooling fan seems to never come on. I tested the fan and that works. What could be the problem that keeps the cooling fan from starting when the receiver is getting heated? Thanks for your help.

Ratnesh, I have this same receiver and the fan only comes on at certain volume levels. Unfortunately I now live in an apartment and can very rarely listen to it that loud. I had the same problem for a little while until I thought about moving the receiver to the lowest shelf with nothing on top of it. This seems to have worked so far although it does still get quite warm. Good luck!

I used the manual downloaded from

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.

I moved and cannot find manuel for sa-dx940 need instruction on how to reconnet wire to t.v. and speaker

The Technics SA-DX940 is made by Panasonic. The manua as a PDF is available here: . The directions for connecting the speakers start on page 14. The connection to the TV is on page 10. To use the SA-DX940 as just external speakers for your TV, connect either the digital audio out from the TV (if it has one) or the RCA audio out from the TV to the matching TV audio in on the SA-DX940.

I hope this helps.
