Sound Work Radio 705, automatic shut off

Hi,  I know the unit will shut off itself after 30 minutes is desired. But my radio also shut off the speaker after it does not see anybody in front of the unit.  There should not be any sensor to detect the presence of listener or wall near by, but it anyway will shut off.  This happens now every time I get more than 2 meters away from front of the unit. This problem is very strange.  Can you help?

After a few minutes of playing a cd or the radio, the speakers make a thumping/crackle noise and the music stops. The stereo stays on. Just stops playing music. Any ideas?


Hello

OK, this is just a suggestion, without analysing the unit myself.

From my experience with these type of units, it is usually overheating of the IC's on the circuit board.
You can do another test just to double check. Turn the unit off, unplug it from the wall supply for about 10 minutes. Then plug the unit back in and turn it on. Now turn the volume very high, without the speakers starting to distorted, where you can still hear a clear sound.

Now, if this is an IC overheating, the sound should start distorting and cutting out. This is actually a very common occurrence with these types of players as well as receivers in general.

Try the above, let me know what happens.

Also, please do not hesitate to let me know if you need any further assistance.

Kind regards
Andrea

When i turn on my sa-ak340 the radio, cd or cassette work only a few minutes after that automatically turn off.


I've encountered that kind of problem.
f61 appear on the screen then shuts down the unit.
The very common defect is your fan, output ic (rsn series).
First check the fan if it is in good condition (disassembling the component is quite technical it need a lot of care).
sometimes the fan is full of dirt that's why it will not work properly which the system sense and uttered the unit to switch of avoid further damaged.

Bose Acoustic Wave music system popping speaker


Had the same problem on the same machine 15 or so years ago...took it to the Bose factory shop in Framingham (or real close )Massachusetts, and they fixed it in 20 minutes...cost around $50...at the time they said it was a real common problem, and an easy fix.

Bose Wave Radio/CD - Sound from only one speaker


Sounds like the audio transformer, but it's difficult to tell because Bose will not release their schematics or parts lists, effectively giving them a monopoly on repair of these sets. On their web site, www.bose.com, they offer to repair most Wave sets for $100 or give $200 credit towards the purchase of a new Wave. Before you spend the big bucks though, you might want to check out the new HD radios. Better sound and MUCH lower prices than the Bose.

Pioneer X MT- 2000 Stereo Bookshelf Unit - No sound!


It definitely sounds like it took a surge. yhe Power Amop IC in those things are pretty sensitive. Any decent repair shop should be able to repair it for under $125.
