I own a BL4000 speaker with type 6642 and Serial 211… that starts to produce a minimal ‘wind/snow/white’ noise after a while after it is turned on, then getting louder by the half hour. Had it checked by a pro and the outcome was the ICE Power amp board is broken.

Does it sound familiar to you and do you know where to arrange a replacement part?

Many thanks!

To answer that we are going to need a bit more information.

1. Does the noise vary with volume and turn off when muted?
2. Putting your ear to each driver (tweeter and woofer), do you hear the noise only from one or both? Note that the tone will be different.
