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?

No sound from speaker but through ear piece I get sound.


Many devices will automatically switch off the large speaker when ear phones are plugged into them. Also there may be a switch or button or prompt on your radio to switch between regular speaker and ear phone jack. Look for that first.
Try connecting and disconnection ear phones while listening to a station and see if the problem is intermittent. If is works sometimes but not every time then it is most likely an internal connection.
You will have to access the inside of the radio to investigate further. Connect a working external music or sound source with speaker wire to the terminals inside the radio that connect to the radio's speaker. If the radio's speaker works with the external sound source then you know it is a bad connection inside your radio. If the radio's speaker does not work with the external sound source then it is most likely a faulty radio speaker. Look closely for a broken solder point or broken/disconnected wire.

No sound radio honda accord 2004


Either radio is bad, or you have a loose connection to speakers, or poor ground connection at the radio. If a poor ground connection, the radio will intermittently not work also. Since radio continues to work, but sound does not, it is probably a bad audio circuit in the radio itself.

My 2002 chevy malibu's radio seems to be shorting out, the radio will work fine but randomly the sound shuts off the radio still shows the radio station and even says which artist is playing but there...


I'd suggest using the balance and fade controls to cut out each speaker one by one. to possibly determine if you have shorted speaker or speaker wiring. As far as the turn signal clicking noise, the hazard switch is the actual flasher unit for the turn signals, and could be the culprit, but the most likely cause is the turn signal switch itself. It is usually caused by corrosion across the contacts, which can be cleaned out fairly easily, but more typically, the switch is just replaced

Radio working just fine But no sound coming from speakers


if the radio still has power the audio amplifier ic in your radio has failed.
take your radio to an electronics repair shop or, replace the radio; this not something you can fix unless you know how to use an oscilloscope.

Sound problem


You have a shorted speaker or a speaker with a bad voice coil. This has been confirmed by the fact that the audio amplifier is shutting down (protection) but the unit stays powered on. The speakers will play for a few seconds or maybe even longer at lower volume, but any length or time or an increase in volume will immediateley shut off sound. This is due to the fact that a shorted speaker wire/connection will ground out or short to one another. If you have checked all connections behind the radio AND at the speakers and found no problems, then it is a voice coil on the speaker. A shorted voice coil will work until the speaker cone moves causing the short or until enough power passes through the voice coil's short to turn off the radio.
Solution:
1. You can use a voltmeter set to check continuity to test for a speaker short. Disconnect all speakers from the radio and connect one side of your meter to ground and the other to the speaker lead. An audible "beep" will confirm a short.
2. The other method would be to disconnect all speakers and re-connect them one by one until the radio's sound output shuts off again. This will be your shorted speaker.
I hope this information was helpful.
