Hi, I have Creative Labs SBS 2.1 370 - I started making weird noises: out of nowhere (no music playing) I heard the booster make some cracking sounds - almost like breaking a twig. Also, I smell something burned, so I want to look inside - there is a panel for the plugs and volume control at the back - with 4 screws - I unscrewed those, and I can pull out the panel (with IC board attached) but only partially as some wire blocks (I guess it goes to one of the speakers). Also, I can't remove the front (with the fabric) as it seems screwed as well - I pierced through the fabric in one of the corners, but couldn't feel a screw there - seems it is glued or thoughtly locked (from the inside), but then how did they close the box? Can't find any other screws (none under the 4 self-adhesive plastic 'feet' either). The set is about 5 years old, switched on daily (although not used for music), so it now breaking down would be inconvenient but not totally 'unexpected'. Any suggestions? Thanks in advance!
