A few days ago, my Techincs SA-AX710 Receiver stopped fucntioning properly. As I turned it on, it started to show the tuner and the radip station number and all suddenly within seconds it dissapeared only to display the word "overload" sequentially. I pushed the Help button and it only tells me to switch power off, I have done so and so far it keeps getting me the same message. Any suggestions?
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

First of all, check all the capacitors. Other than that, it needs a repair guy to have a poke about inside it with a screwdriver. Has anything happened to it lately that could have upset it a little bit? such as a powercut or had anything done to the plug? (e.g. change of fuse, and put in one that was a different rating) And is it plugged into a surge protection socket, or a plain old fashioned electrical socket?

I have the same problem on a SA-AX810. Plays for about 5 minutes then kicks off with the overload error. I thought it was getting too hot and replaced the factory fan with a 110v "always on" fan. Still no luck, 5 minutes and it's in overload again. Any suggestions?
As long as i have the bass knob in the middle and keep the volume knob below a quarter of the way it will stay on. As soon as i cut it up it says overload.
my problem is precisely what is described on the previous page
My SA-AX710 overloads intermittently. The problem is a broken solder joint between a pin on one of the power transistor modules and the circuit board. To fix it, I removed the circuit board from the case and resolder the borken joint. Opening the case is easy. First remove the top of the case. Then remove the 3 screws in front. The front panel can then be pulled off. After that, remove all screws holding the connectors on the back. The circuit board can be detached from the case by removing all the screws from the top of the board. Broken solder joint is probably one of the most common problems with modern electronics.
I have exactly the same fault with my AX710 - 5 mins of playing and I get an overload error and the amp cuts out.
