Introduction

What you need

Step 1

              Exterior Housing

Pry the exterior housing off the iHome iP37. You may need extra leverage to do this.
Note: This step is the most difficult due to the way it is attached. The glue holding the exterior housing to the internals does not break easily. You may want to use iFixit’s iOpener to soften the glue.
Note: The process is the same for both the upper half and the lower half. To identify the halves, look for these details: the upper half has a metal grid, and the lower half has buttons. If you are replacing any other components, pry off the lower half.

Step 2

              Lower Half Casing

Remove these four 9 mm screws from the plastic casing; you will need a Phillips #2 driver to do this.
Remove the flanged 9 mm screw from the counterweight; you will need a Phillips #2 driver to do this.
Lift and remove the counterweight.

Lift and remove the counterweight.

Step 3

Lift and remove the plastic casing.
Note: It is best to lift the casing starting from the side without the protruding 3.5mm audio port and power port.
Reminder: During this process, a rubber cover will likely be dislodged. Make sure to re-seat this cover on the small pegs before putting the plastic casing back on.

Step 4

              Preliminary Main Board

Remove the two 9 mm screws that hold the main printed circuit board onto the rest of the iP37; you will need a Phillips #2 driver to do this.

Step 11

Carefully peel away the black melted plastic that covers the connection points from the four wires to the main board.
Make sure not to pull any of the wires out. This will make soldering them back on later more difficult. To avoid this, it may be easier to peel the melted plastic away in small chunks.

Step 12

Desolder the two red and two black wires from the main board, which will completely free the main board from the rest of the assembly.
