it could be overheating - try aiming a fan at it for a while, see if the problem stops.

yes it can be fixed , the input may have shorted and is now protecting the other circuits. it will need to be looked at and tested to make the repair. so calling and probably having to take it to, an electronic repair shop will need to be done.

SOURCE: I have a Technics SA-AX610 receiver that says overload .

From the manual pg 27....... "The protection circuitry has functioned because the positive and negative speaker connection wires are "shorted," speaker systems with an impedance less than the indicated rated impedance of this unit are used or under severe use, such as loud volume, excessive power and in an excessively hot environment."

100 watts per channel both channels driven into 6ohm. You can download the owners manual at http://www2.panasonic.com/consumer-electronics/support/ (Technics and Panasonic are both made by the same company) Then enter your model #. the specs are on page 23 of the manual.

SOURCE: Technics SA-G9057 overload

Check the fan connections at the back. The connections (just two flimsy metal prongs) came apart (I believe), so I have had to re-enforce them with electrical tape so the connections stay together until I investigate a further replacement fan. For now the connections are extremely sensitive to motion/viberation/impact/etc... but it does work now.

Why am i getting an overload message when i don't have anything connected to it ?technics sa-dx 1040


double check there isn't a piece of wire that has broken off the speaker cables and is shorting two of the speaker terminals together. The unit needs to be turned off and unplugged for a minute to reset the protection circuitry. If this doesn't fix it, there's likely an internal failure.

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.

When I turn on unit, a message "overload" appears.


Check the speakers and the power supply for any signs of shorting.
This is due to the fact that the safety circuit works to switch off the set preventing a high damage.
So check the output for short or the presection .

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.

1 You may have a failing power supply regulating circuit in you amplifier and the fail safe circuit is trying to protect the rest of the circuit.
2. there may be a voltage overload at the primary side of the power supply circuit which in this case is causing it to shut down.

An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.
