No Power My speakers worked perfectly for a year and a half. Then I moved the room where my computer was located and the speakers will not turn on. It is being read by the computer that I have a sound system. However, the green light will not turn on. Are they just dead? I have checked the plug, and I have used other plugs. I have done everything I could think of, but i am out of ideas. Please help!

check the mass terminated cable connecting the controller to the base speaker. This connection becomes flacky generally requiring a good contact cleaner solution being needed to be applied to restore the connections.
Go to radio shack and ask for a plastics safe contact cleaner then after disconnecting the mass terminated cable spray it liberly. Then reinsert while still wet then work in and out a few times. You can do this for all the cables connecting to the pc as well. This should restore your dead channel....hop it works :-)

Neither the amp or the sub have grounded power cords.

I have discovered the ML Dynamo takes about 30 minutes to switch to standby in auto mode.

With speaker level inputs connected to the Onkyo A807 amp, both units powered from the same wall outlet, Dynamo sub on Auto, the sub hums for about half an hour after the Onkyo is switched off, then the sub goes quiet. Not so good.

I connected a bonding wire between the two units on 3_7_09. If I smoked some old audio gear I could just look at that as an opportunity, right?

Works fine. Now I have the ML powered from the wall and working normally.

u'r scanner have to turn on first for the computer regocnize
try another power outlet, if the scanner turned on, it means the power outlet u used now is poor...
u can check the power adapter first

Hi there,

just go to the manufactoring website, all the drivers will be on there :)

Buy a new one

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.

My problem is solved!!! I called my neighborhood TV repair shop. The technician suggested I check the Internal Speaker Switch on the back of the TV. And sure enough, I had accidentally move the switch to the OFF position while carrying it from one room to the other. Ahhhhhhhh!!!!!!!!!!!!! my 13 year old JVC is as good as new!!!!!

switch your subwoofer off from the socket for at least 30 minutes and check if the noise is still there,if its still there open it and play a movie then press it lower if the sound stops then you will have to put some toilet papers at the back of it ,thats what I did to mine.

This can be caused due to an increase in local interference. The hum is decreased when you plug in the satellites because the interference is spread over a longer area. You may notice that speakers tend to hum around things like cell phones and power outlets. To see if this is the case, move the speakers to another part of the room if you can, slide the desk around, plug the computer in at another room, something like this. If the hum gets louder or quieter, it is interference at your new place. This can be solved by finding a new area to set up your computer stuff at. Since it's mostly the subwoofer, try elevating it off the ground, there may be a power main running under the floor.
