Technics sa-ex600 receiver displays error message 'overload'

...and instructs user to switch off the power. This occurred after the device was moved to another location and the speakers were reconnected. The connections were done wrong, so I unplugged everything again, but the device still gives the Overload error. Is there a reset function anywhere?

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

SOURCE: Technics SA GX490 - Overload

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."

SOURCE: Overload on Technics SA DA10

Cracked solder joints due to excessive heat cycling. Do not place in a shelf system. Top MUST be open for 1 ft. or better for proper convective cooling effect. Mine suffered same fate but repaired locally.

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.

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.

Technics SA-DX940


overload, usually means that is overloaded. i've had the receiver for about 4 or 5 years now and never had problems with it. It was sitting ontop on my tv for those 4 or 5 years, and i haver noticed it untill just recently, (when i bought a new tv and i had to get a stand for it, and i had to stick the receiver in it)that is runs very hot, very quickly; Maybe that is the problem you are having now, that the thins is older and maight be able to handle it as it id b4. Maybe you made some changes to your set up: new speakers, etc.
