Check the power relay RL703, I have seen these with burned contacts cause this problem a few times on this unit. Replace relay or bypass the two normally closed contacts.

SOURCE: overload protection

Doe this always go into overload independent of the volume level? Try disconnecting the speakers completely and running the set. Does the set shutdown then too?

Thanks,
Dan

Overload sa-tx50


Most overloads are caused by the main output devices. They will go short circuit if for example speaker wires have come into touch. Another cause is high volume or a faulty speaker. Or poor ventilation around the amp causing excess heat.
The only cure is to replace the device(s) generally located on the heat sink.

Technics sa-dx1050 overload


if any one of the channels was shorted out, even momentarily, that channel's output transistors would likely be blown causing it to stay in protection mode. (or overload as you put it). Time to visit the repair shop.

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."

Technics SA-DA10 jumps into overload after 10 minutes


Have you tried connecting speakers? What was the result?

Yes, when you turn the volume up on these amps (or when the output gets past a certain level) the cooling fan should automatically come on.

Overload message in technics model SA- EX400P-K I have an older Technics system. It has worked great for years but now I get overload whenever I turn it on. Have changed speaker wires but no use. Any...


The overload message is the old version of "protect" mode. This means that a problem has been detected in the output amp section and that section is shutdown to prevent further damage. Your unit uses amp-pacs. One or more are bad. These are marked RSN3305P and cost about $66 each.

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.
