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 seperates


I'm not familiar with the exact system you have but the simplest cause to this problem woulf be a sticky switch, since power is reaching the system for the stand by light to come on.

It is possible to test switches like this by opening up the stereo and touching an unbent paperclip across the two metal contacts that go into the switch. If it comes on then you know your switch is bad, however be warned that running electrical equipment with the casing off puts you at risk of receiving a shock if you touch the wrong part so I don't officially recommend this.

If the switch is faulty then you can either try cleaning it by spraying a contact cleaner such as IPA into it or just replace the part (though this will require soldering).

Otherwise, some stereo systems have an internal fuse that will blow to protect the circuit if you overload it so have a look for fuses on the circuit board.
