Other Probable Causes of Noise

Speaker noise may also be caused by interference or noise on your AC line. Make sure there
are no large appliances sharing the line, or halogen lamps or light-dimming Triac devices.
Try connecting your system to another AC socket on a separate line.
If the hum is heard from within the DMC-1 and not through the speakers, this may also be
caused by interference on the AC or DC lines. The power transformers may turn this interfer-
ence into an audible noise. Internal hum can be made worse by a shelf or cabinet resonating,
so try moving the DMC-1 to another shelf.
Try moving your components further away from the TV, especially if you ever notice the screen
has changed color in the area closest to the component.
If you have very high efficiency speakers, these may tend to reveal noises which other speak-
ers do not.
