My Bose companion 20 right speaker will not work on my I pad

i hav the same problem but all three shut off ,and i have to shut off and turn on again

You don't write which operating system you use, but generally you should be able to choose where the sound output goes in the Sound Properties in Control Panel.
If however Sony decided to put some special software that does the thinking for you, and directs the sound output via the HDMI when connected, then you have to dig deeper...

oh ok. I'll chek the input again Thanks

Check first that you have connected the speaker to the right output. For example on many computer there is an aux output marked in blue that can give you this problem.

If the problem does not depend from the source, then that sounds like an internal fault on your Bose system.

Leave the Bose unplugged from power and from computer for one hour, to get rid of electrostatic charges accumulated inside capacitors.
If that does not get rid of the problem, then there is an internal fault, either a short on speaker wiring, or a fault on the internal amp circuit board.

Are you using the usb cable to power the speakers?

I had the same problem right out of the gate, the volume dial on my control pod for my Companion 5 wasn't working, however, the touch pad and LED worked. I called Bose customer service and was instructed to:

First, unplug the power directly at the back of the woofer while the unit was on;

Next, I was instructed to unplug the control pod, visually inspect for any damage/defect;

Finally, re-seat the control pod on the back of the woofer and then lastly plug the power cable back into the woofer.

It worked like a charm. I hope this is helpful!

from what I've read, the imac has a 3.5mm (.138) jack while the Bose jack is 1/8 (.125). very small difference in size (.013), but enough to cause problems.

Hi,
You can purchase it from amazon, click here Amazon com bose control pod and choose, which one fits to you.
I hope I was helpful
enjoy

Try going to control panel, sound, then configure the system to the Bose. Hope that works.
