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.

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

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.
