Bose companion 2 series II headphone jack not working

We've had these Bose Companion 2 Series II speakers for about a year and the headphone jack has always worked fine until now. We just bought a set of Koss headphones tonight and plugged them into the headphone jack and there was nothing - the sound was still coming from the Bose speakers and nothing from the headphones - we took them back out and plugged into our laptop and they then worked so I don't know why they won't work with the Bose - any suggestions?

    Never mind. Called Best Buy and it was still under warranty so they are going to replace FOC. Thanks anyway, and if you want to still post answers in case others need it, then feel free. ;-)

The fact that everything but the power amp is still working, it could be only a fuse protecting the output that needs replacement although this fuse is probably circuit-wise after the main fuse you have already replaced and could be soldered on the board. Worst case, the output modules are blown and require replacement and depending on the power level it may be worth repairing instead of replacing.
Most modern electronic devices can be set or adapted to line voltages from 100-240 Volts and a good percentage of the devices, using the common switched mode power supply don't need any changes made by the user since they can be inherently 'auto-ranging.'

Hi,

you can find an screws because there is no screws on the speaker box. The speaker box/cabinet is clipped together. You will be needing a flat screw driver to successfully open box.

Look at the side(s) of the speaker(s), you will see the where the box it joined together, use the flat screwdriver to put them together. Putting apart might not be that easy, so you will need to apply some force to take them apart.

You can use a gum or glue to put the speaker back together, because it might not completely join together like before.

Good luck.

SOURCE: Bose Companion 3 series II speakers aren't producing sound (imac)

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.

Can i connect a tv to a bose series ii system


Yes you can, only thing is you may have to buy a 3.5mm phono jack to 2RCA converter.Because all standard TV audio out is RCA sockets unless you are planning on connecting the headphone out of the TV. This has an advantage, you can control the volume using the TV remote, but the disadvantage is if you turn up the TV volume very high the Bose may distort due to input overload .

Can I hook up the Bose Companion 2 series speakers to my HDTV and get acceptable sound?


Hi,
Well if you currently find the sound of the Bose acceptable and your inbuilt HD TV speakers poor, then the answer is yes. Should you not like the sound of the Bose, plugging them into an HD TV won't make them sound any better :-)

Just use the headphone out of your HD TV to connect. You may find you need to enable the headphone socket/volume via the menu settings on your HD TV
