Question about Audio Players & Recorders

1 Answer

I have a pretty old Panasonic SA-AK630. At some point I started having the following problem. Once the sound is turned up to a certain point, the speakers are cut off and only the subwoofer is working. This is solved by "restarting" the speakers by plugging headphones in and then out. The cut-off seems to be triggered by certain frequencies as the "threshold" level appears to be different for different types of music/film, but is always the same for a specific song. Additionally, this level seems to have gone down over time -- I can only play music really quietly now. Not sure if this is relevant, but the cables to the speakers are extended to 2--4 meters.

I think you're indicating a self-protection problem.

One or more speakers or amps could be going South on you.


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


Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance 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.

Panasonic sa-ak630. i turn it on an display said f 61 an turns back off all in a matter of a second or two... wires are all good.. and even just left everything unhooked an still no help... manual said...


F61 is the shorthand for Panasonic machines to mean protect mode. See the link below for a generic explanation of protector. Specifically, in your machine, either the regulator IC has failed or the output amp IC has failed. In any case, the repair will not be cheap. The output IC costs between $75-$125 depending upon the specific IC.

Panasonic Receiver SA-XR25


I thought it might be heat related, so I put a small battery operated fan behind the receiver, and voila, no more clicking. I just have to invest in rechargable batteries or an electric fan.

I have a panasonic sa-ak630 and it works and everything i just dont have any sound at all


I had the same stereo, I found that the issue you describe happens often under heavy use especially with the subwooferon max. Simply unplug the stereo unit from its power source for about a minute and plug it in and it should work again. Hope this helps.
