Logitech Z340 Power speaker problem

Damage may be confined to just the power supply if you are lucky.

i have this problem toooo

what is the cord that hooks from the speaker to the computer?

I experienced the same problem, where the symptom was initially that the volume setting was misbehaving in that you would press the to increase the volume and it would go to the maximum, and likewise press the down button and it would go to the minimum volume.  Then the screen appeared incomplete and finally it did not power on when pressing the power button.  The solution I found was to unplug the power (overnight in my case) to allow any power to drain from the unit and transformers, and then plug it back in.  It powered on afterward.

take out the battery

i did the same to mine,

just replace the power transformer with one that accepts 110-240 volts

easy to do, but check cost might be better to buy a new set depends on your situation

See link below. There is a reset button at the bottom of your speaker. use a pen and press button for two seconds to reset speakers. This link below should help.

maybe the first step could be checking the subwoofer's fuse.it is located over the power supply connector.

hey u r using speakers..so i think power is not suff for them to run..so use dc flug boards..i mean direct curr...
y do u try for a batery??itz waste of money

I think maybe the speakers blew out because of how loud people put there IPods. It is busted so buy a new one.
