Note: This is one of the more difficult fixes. Make sure to keep track of your screws and everything you remove from the device as you take them out. Not doing so may cause worse problems than faulty speakers.

In order to do this, it would be wise to keep a tray with several compartments and some sticky notes to separate and label screws from specific locations on the device as you remove them.
