I have an old Technics amplifier, SA-EH500 that would turn on and off again when i press the button

I have changed the fuses, i checked a few AC power pins and they seem to be recieving power, the sound processor is connected.
What should i do?
I have the same problem and would also like to know if someone has a resolve.

Most likely the output section has a problem and the unit has entered "protect" mode. Not all receivers make it obvious that this is the problem. Without seeing the unit and poking around a bit, I can't say for sure, but that is my best guess.
