re: SA-400
There’s no sound coming out of the speakers when I plug it up it seems like the speakers outlet is not working can someone please help me troubleshoot it
re: SA-400
Do you have a voltmeter? If so with the speaker wires disconnected from the stereo and make sure the wires are not touching each other place the probes across the speaker terminals. You should get 4 or 8 ohms depending on what the label says. If they are o.k., remove the cover and see if there 2 fuses. Replace whichever is burned out and turn it on. If either burns out then you have a short somewhere and will need a schematic from HiFi Engine. I checked and one is listed. While you got the top off, check for any abnormalities .
