Solution
Short-Term (3/9/2004): Factory implemented Work Instruction (WI-01-3080-017)
to ensure proper assembly (fun-light flex, speaker/elastomer alignment, and
screw torque).Lower Kapton tape (1190142N01) was added to secure physical
connection between audio hinge flex and speaker elastomer. See Fig 4.0 below.
Long-Term (5/25/2004): Factory crossed-over to a new version of foam snubber.
The 7589762N01 Rev. B Snubber provides insulation to all components and is
100% adhesive backed to secure physical connection between audio hinge flex
and speaker elastomer. Rev. B Snubber is also more durable which allows it to
be easily removed and replaced during repair. Placement of the upper and lower
pieces of Kapton Tape is no longer required with the use of the 7589762N01
Rev. B Snubber. See Fig 5.0 below.
