    Thank you soooo much for this info! I took it into a shop yesterday morning, they called in the afternoon to tell me it was the power suppy, and that it had short out! They are replacing it for $20.00! A lot cheaper than what I was anticipating! Phew! I called the tech this am, and asked if what you suggested could have contributed to the overload problem, said that was the first thing he checked and found that all is good in this area. Once again THANK YOU so much for taking the time to respond to my question!

Sounds like you have a "nuisance shutdown", caused by failure of the speaker protection circuits which are notorious for problems. Unfortunately, more and more newer electronic units fail this soon. It's not really the manufacturer's fault, it's more that individual electronic parts have gotten cheaper to compete in the marketplace, and are more likely to fail than in the past. Unless you used to play the receiver really cranked up (which would suggest failure in the output circuits), you have a nuisance shutdown problem. At any rate, I would question the circuit design and probably buy a better brand (such as Denon or Sony) rather than take the chance of spending money and having it fail again soon. Just my educated opinion (technician for 35+ years).

My technics av control stereo receiver sa-g76 keeps shutting off(overload). can you please advise on how to avoid this situation?

Is there anything on top of the av receiver? Try and run the reciever so that it has enough cooling. B) Allthough overload, there is a possibillity it is causes by speakercables who are shortcircuiting once in a while. Usually somewhere at the back of the reciever or speakers.

My amp says overload whenever i plug speakers in to it. its a Technics SA-DA20

Check your wiring. Make certain there's no breaks and the two parts of the cable do not touch each other.
If it still says the same with good wiring you have probably developed a fault in the main amp. A failed transistor etc, located on the big heat sink.

My Technics sa GX350 tuner keeps going into overload. It's the only thing plugged in.

Hi mate, had the same problem with my amp.. Take the top off and there is a fan at the back, there are 2 piece's of copper flat wire that touch together and these do not touch anymore so when its turned up or the bass gets stronger it cuts off as the fan should kick in at this point. If you can get these to touch again (bend them) then the problem will be gone!! I have had to do this a few times now though so this is not a long term fix.. I may try soldering!

My Technics AV Control Receiver SA AX530 is in overload

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

If all the speakers are connected proper and it still says "Overload!!!!!"

Your output amplifier module is most likely failed.

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.
