These units are designed to only run the fan when necessary. If the unit is overheating, there is a problem in the detection circuit. This is a relatively inexpensive repair. If you are getting overheating when running at a low volume, it suggests that the speakers are not matched to the amp. In other words, the amp is expecting an 8 ohm load and is being presented a lower ohm load. This makes the amp work harder and generates more heat. Check the speaker wires and make sure that they are not frayed or crossing in any manner. Also, verify that the rating of the speakers is correct.

Update this with what you find.

Thanks,
Dan

It is unlikely that the display itself is faulty although it can happen. The typical problem is either the backlight is defective or the suply to the unit has a bad connection. If you can solder, try resoldering the pins on the display itself. The pins on the ends are the power and ground. I don't recall whether or not your model has a separate back light bulb or not. That too could be burned. Chack for that too.

Keep us posted,
Dan

Have you noticed if the speakers selector switch in the front panel is set to off ? That position for the switch is only suited to listen heaphones. Good Luck.

My Technics SA-AX540 AV Control Stereo Receiver keeps shutting off and on and displays overload. Does anyone have a fix for this problem?


Heat?


Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.


Check for loose speaker connections as a root cause for intermittent shutdown.

Same problem


The overload indication tells us that there is a problem in the final stage of the amplifier section. This model uses an AMP-PAC or large amplifier IC (part number RSN-3305) which is now defective. If you can solder, try resoldering the pins on this IC. Sometimes a poor solder connection can cause a voltage offset that will be detected as a fault and shutdown the system like this. If the resoldering fails, the IC will need to be replaced. Parts cost will be in the $75-$95 range.

Hook up pioneer stereo amplifier model SA-1270


for audio system always you have left and right channels.
get the output (left&right) from tuner---go to equalizer input left&right.---from equalizer output go to amplifier inputs.and certainly from amplifier output to speaker.
