SOURCE: technics sa-ex300 says overload ?
it could be overheating - try aiming a fan at it for a while, see if the problem stops.
SOURCE: SA HE200 ~ Overload at power up
First of, be sure volume is turned all the way down before or as you are powering it it.
Second if that does not work disconnect all speaker, and input/outputs. Power the device on and see if it says overload.
If it does skip the rest of these steps, your capacitors are bad or the power supply is no longer functioning correctly.
If it doesnt, start with testing each speaker at power up. Match the speaker to the output it goes on, power the device see if it says it.
If it does on any speaker test it is a speaker issue or a terminal issue. To test for terminal or speaker issue plug a different/ known to work speaker in that same terminal, if it doesnt say overload it is a speaker issue, if it does say overload it is a terminal issue.
Once you have made sure all speakers and terminals work correctly start plugging input and outputs in and test individually.

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.

SOURCE: Sa-da8 overload and off
I had the same problem. What I did was hard wire the fan so it runs whenever the unit is on. I had the reciever set for low impedance, when I turned this off all works fine. (Low impedance is only for speakers with an impedance of 6 to 8 homs or less)
