over load means your speakers and its cable----please check it for bad cable or bad speaker------try to insert speaker one by one and test each time to investigate the bad one.--------if every thing is ok and you keep good ventilation around your receiver (no blocking of ventilation holes)and you still have a problem your protection circuit in your receiver needs to be checked by service technician

SOURCE: on switching my technics sa-dx750 it says switching off overload

The question is what is causing the overload? The power supply or the output devices on the heat sink?
If you have accidently shorted a speaker wire, then the answer will be output devices, otherwise it could be anything in the power section. You may find a burnt or damged device with either of the causes.

No sound from left channel on my Technics SA-R 230


May just be bad connections on the speaker relay. Flip the main board over, and check those connections. It is pretty common on these older models.

I am playing Cd's and have a pair of Definitive Technology- Model BP-10 tower speakers connected to my Technics SA-DX1040 5.1 Channels Receiver and while the music is playing, all of a sudden the music...


There are 2 major possibilities and since you didn't say if the sound comes back here's the general split.
1. The power amp section could be having problems and/or protection circuits are kicking in. In this case repair of the amp will be needed.
2. There is a bad connection somewhere making the audio path go bad. In this case a good can of contact cleaner applied to all switches and controls may help. If not, the bad connection may be internal. If tapping (or rapping) on the unit makes it come back, there's probably a bad internal connection.
If letting the unit cool down brings back the sound, its the power amp section.

Max. wattage for speakers w/ Technics Receiver SA-GX100?


I too have a Technics SA-GX100 and it's rated at 2 x 40W @ 8 Ohms. I have the Technics SB-2840 floor model speakers hooked to it, which are rated at 200W Music Input - 8 ohms. It sounds very nice just to be a 40W receiver.

Technics SA-DA10 Receiver-no sound


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.
