Receiver says power overload, turn system off

I have a Technics SA-GX 470, sometimes the receiver is turned on and it says power overload right away, at other times it takes time and then says overload, turn power off. We have had this system for years and it started about a year or more.

It probably needs soldering of the voltage regulators and/or output IC.
I think that model has an access panel on the bottom (it may need to be cut out then rotated and screwed back on when done).
If it doesn't have the panel the main circuit board needs to be taken out to access them.
The regulators and output IC are mounted on the main heat sink. a little soldering and it should be good as new.

On switching my technics sa-dx750 it says switching off overload


The question is what is causing the overload? The power supply or the output devices on the heat sink?
If you have accidently shorted a speaker wire, then the answer will be output devices, otherwise it could be anything in the power section. You may find a burnt or damged device with either of the causes.

Overload on sagx550 technics


Disconnect all speakers at the receiver then turn it back on. If it still goes into "overload" you need to have the unit serviced. If it stays on, post a comment and I can walk you thru troubleshooting your system.

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 SU-G91 OVERLOAD PROBLEM


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.
