Overload on Technics SA-AX710 Receiver

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? My Technics SX-GX690 receiver overloads when playing beyond a certain volume level. If I press Help it simply tells me to switch power off. When I turn it back on, I have to turn down the volume, otherwise it keeps overloading. Is there an easy solution to this problem?

SOURCE: Overload on Technics SA-AX710 Receiver

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?

It keeps saying overload whats that mean


you have a blown or shorted speaker, or you have a blown input/output in the unit.
Look up my tip on transistor checking, and look for bad capacitors too.

Our SA-AX7 says overload. What do we need to do?


Do not continue further. There is a short circuit in the power supply or output amplifier stage. Disconnect power. The unit is preventing a fire or further damage to the system. Also, check the speaker output terminals for wires shorting the terminals together. Otherwise, an audio repair shop must isolate the problem. More than likely a transistor has shorted in the output stage.

My Technics AV Control Receiver SA AX530 is in overload


An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.

Overload at medium (4-6) volumes. Can you adjust or disable the overload protection on these Technics amps??

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."

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 the screws from the top of the board. Broken solder joint is probably one of the most common problems with modern electronics.

Technics SH-AC300 Connection to Power Amp & Pre-Amp


Hi!
The problem is, that your SH-AC300 needs an amp with 5.1 input (but no decoder). For this purpose technics delivered SA-AX710.
So if you'd like to use your current equipment it would be impossible.
The only option is for you to buy 2 more Power Amps (SE-A900S), so that each of 3 amps would take care for one part of music. (one for FL, FR; one for RL, RR; and one for sub and center).
Another option is for you to buy SA-AX710. Then all the problems would be solved with it.
