Question about Technics SA-AX540 Receiver
I have a technics su g91 amplifier and speakers a and b will not work and i believe that it has to do something with the "over load" icon being lit up. I was wondering what that specific icon represented and what i can do to fix it?
I had the same problem. As soon as the volume reached about 24db it would go into overload. I was able to fix it by soldering all the connections on the larger power module. The one connected the the heat sink. When I took it apart there where several solder points that had come loose.

Most of the time you should check the fan.that can cause it to go into protect when volume turned up

I have a technics GX 650 model. 3 years ago i put it inside my cabinet for the same reason that whenever i turned it on it stays in overload conditon. so this morning March 5, 2012 i try to dissamble the whole unit and cleaned it form dust by using paint brush and electric fan. i found the solution by just cleaning the unit fan circuitry its copper foil contacts and it works again. this unit is 19 years old already and back into its old form. so the only the circuit in the fan had a problem i thought it was the power ic.

OVERLOAD means that input signal level is too high. Can you be more specific? From which source you play music when OVERLOAD icon appears?
