your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck

Could be the impedence of the speakers that you're connecting. The bose amp was designed to drive 8 ohm speakers.

The problem is not the transformer. You now have shorted output transistors at the very least. By corssing the wires you presented a zero(0) ohm impedence load to the output section. It quickly went into overload. Before the fuses had a chance to open up, the outputs fried. This unit will require new output transistors and perhaps the previous driver circuit will require parts as well. Figure on $20-$50 in parts plus hte local labor rate for the repair.

It will be on the inside of the amp, located on the power supply board. The are many types of fuses, so it may may not like like you expect.

Before somebody can help you you need to give us the make and model number. You have the unit and know what it is, we don't. Also What media center are you talking about. what else is connected, and define not work!

Spend a bit of time and give us some information, what you state us useless.

Unplug your Bose system for 5 minutes to reset the processor ic, now plug back in, if no change! contact Bose, this is a product that is only repaired on site at the factory and they have the parts.

While living in the States I purchased a Bose Acoustimass 10 system but have now moved back to the UAE. As the system operates on 115 volts ONLY I would like to get it work on 240V without having to use a step-down transformer. By changing out the transformer form 115v to 240v will it work or will I have to change any other components within the system. Can anyone help me??

You need to change the internal transformer, it is not simple unles you have some electrical knowledge, I made the same mistake and ended up selling the us one and buying a 240v one

What you need is simply a power converter device that knocks the power down for your device. Look for a UK (European) to USA power convertor on somewhere like Amazon.

If there is not an external round push and turn style fuse port then it is in the unit itself. You will have to take it apart.
