SOURCE: not working

Operationg instructions says it is "F 70". When it appears it says to turn the unit off, disconnect the aC power supply cord, then reconnect and turn theunit on. Consult your dealer if "F-70" remains on the display.

SOURCE: Overload on Technics SA-AX710 Receiver

Turn it off...remove all the speakers and turn it on....If it goes into the protect mode. you have a bad power amp. That's the big black flat things attached to the cooling fins.. one or both is shutting the system down. If it doesn't trip out, plug a head set into the phono jack and see if you can hear the music there. Can you turn it up without tripping.... if it's still ok...hang one speaker on the system, if it trips thats the bad leg...check the speaker/wire

SOURCE: 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.

Amp keep's sating overload


Have you tried disconnecting all the speakers and inputs and turn it on?
If it still shuts off you have an internal problem, if it stays on, connect one item at a time until it shuts off and that is the problem.
