My portable Bose speaker has just started to buzz a few times in quick succession, then stop for half an hour or so (whilst not in use). I have unplugged it from mains power and disconnected the iPod but still happening. Any ideas how to stop it?

Depends what it is. Make and model, tubed ot flat panel, Plasma or LCD etc etc etc

You toasted your battery. Unfortunately, you are more than likely out of luck as water damage is not covered under the Bose warranty.

The next time, hopefully never again, you drop an electronic device in the water, DO NOT TURN IT ON! Remove the battery and let dry for 48 hours, with all possible covers removed.

these units are very compact and are not to be used for long periods of time at peak performance a few things may have happened
1-(you may have over charged the system)
2(the batteries my have leaked and failed)
3( the ac-dc components have failed)
in any case the system must be checked by a tech there's not easy fix for this unit. thanks for asking god bless!and good luck!

I have the same problem but now the static sound is on all time. did you solve it.

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

Static can be caused by a few things.

Does the static persist if you unplug the audio cable from your computer?
If so, the static is being caused by the amplifier built in to your speakers.
If not, the static is probably caused by interference on your sound card. Try plugging the speakers in to a portable media player. You might need to replace the sound card in your computer.

The coupling capacitor on the phono input is possibly become leaky. Try replacing any small electrolytic capacitors you see near the input within the amp.

Sounds like you need to take them back for exchange. A new electronic product is most likely to fail in the first few months, when any weak or defective parts that made it through final test at the factory decide to **** out after a few hours of use. This is a very common situation, especially nowadays with manufacturers buying the cheapest parts they can find, and the general public crying out for lower prices instead of paying more money for better quality. Bose has traditionally been "top of the line" stuff, but even they have to cut corners to keep prices low and sell stuff in this economy.

sounds like interferance try moving the speakers around maybe away from the monitor and try turning off any thing elec around your pc to find out maybe what is causing this
