Question about Technics SA-DA10 Receiver

Technics SA-DA10 Receiver-no sound

Worked fine until one day I was playing electric cello thru it. Sound stopped. NO longer produces sound in any speaker output, but still does in head phone output but only in one channel (left). discovered speakers I thought were 8 ohm really are 4 ohm, but had been using them for 2 years. cooling fan also is not coming on but I don't know if it should be on whenever receiver is on. Fuses on power/big transformer board see OK, can't find another fuse but haven't fully disassembled it to look. Front end still lights up, the thing looks like it is functioning normally as far as panel lites and changes with switch changes but no sound. Turning off and on is no help.

    Similar problem here, but powering down for 15 minutes gives me 10 minutes of audio, then goes off again. Sub is still working, can tell if I turn it up full blast. By the way, the fan is designed not to turn on until there is a fire, then it turns on and fans the fire....(technics only)

Most of these problems are rooted in a failed power amp module.
I'm working on an older technics unit but with the same troubles.

Audio braks when volume 1/3, permanent


If with another position of the volume buttom the sound is normal, maybe the problem can be dust or something jammed between volume buttom and its knob. Try to carefully pull out the volume buttom from the unit and then clean its internal part with some neutral lubricant as well as the knob where it it is fixed.

My Tchnics Sa-Da10 shuts down on what appears to


Ahh technics. Technics always had overheating problems, trust me. Every since they started, their amps would get so hot they would hurt to touch. The reason the fan is not coming on seams to be something inside the circuit board. I'm sure that technics could fix this. If the fan works out of the receiver, then it must not be the fan. ;P

I would maybe get a computer fan, and just put it on top of the receiver and turn it on, or send it in for fixing. Also, do you have to crank the volume to get the speakers to play at your volume, and does the impeadence match the receiver. Because you may be pushing the receiver too hard.

Which port do I plug in MP3? aux or phono. This is a Technics Sa 200


You'll want to use the AUX, because it, for sure, does not have any RIAA equalization, which the phono input may or may not have.

Short answer: Plug the mp3 player into the AUX inputs.

Technics SA-DX930. I ran digital optical cable from the TV to the receiver using the tv/dss mode. It worked well for 4 months. It stopped working. I can get sound out of the receiver and speakers using...


If the only thing not working is the optical input, it is possible that the optical converter is defective. Without seeing the actual unit and testing the IC, I can't say for sure. If you have test equipment, let me know and we will attempt to track this down.

Technics SA-DA10 jumps into overload after 10 minutes


Have you tried connecting speakers? What was the result?

Yes, when you turn the volume up on these amps (or when the output gets past a certain level) the cooling fan should automatically come on.

Technics SA DA20


I have a Technics SA DA20 control receiver. I was given it by an electronics workshop and it has this same error of OVERLOAD coming into the display when switched on. I removed the plates from underneath and re-soldered as far as I could all the points along the stereo amplifier ICs and as far as access would allow. The unit then worked normally for several hours. I was very pleased, and went out shopping!. But on my return after it had been off for about an hour, the same problem has come back. But my boss at the electornics workshop thinks it it just a dry joint, or series of dry joints. The unit is complex to dismantle, so patience and care is required in taking it apart and making a note or diagram of how it comes to pieces and how to re-assemble it after the board has been re-soldered. It does not appear to be a component problem or fault with the SVI power amplifier ICs.
