DOSS SoundBox Motherboard Replacement

Step 1 DOSS SoundBox Grille Removal




• Use a small plastic opening tool to gently lift the side of the grille.
• Gently slide the tool to the front of the speaker.
• Repeat the process on the bottom of the grille.
• Gently pull the grille off of the speaker enclosure.
• Pry with caution, for the grille is fragile.
Step 2 Speaker



• Use the JIS #00 screwdriver to remove the 3/32" screws that secure the speaker to the body.
• Remove the smaller 3/32" screws that secure the left side of the speaker with a JIS #1 screwdriver.
• The smaller screws are still the same length, but they have smaller screw heads. You can use the same screwdriver for both.
• Using a Magnetic Mat throughout this process will help prevent losing screws.
Step 3
• Use the Plastic Opening Tool to gently lift the speaker enough to see the connected wires.
Step 4
• Use a soldering iron to de-solder the two speaker wires from the speaker itself.
• The speakers are ready to be removed and replaced.
• Ensure that the device is turned off when handling bare wire.
• Soldering iron is very hot.
Step 5 Battery
• Use a JIS #00 screwdriver to remove the four 3/32" screws that attach the base-plate to the speaker enclosure.
• Use a magnetic mat to prevent the loss of screws.
Step 6
• Use a JIS #1 screwdriver to remove the six 3/32" screws marked with a red circle.
• Remove the two 1/16" screws marked with orange circles using a JIS #000 screwdriver.
Step 7
• Remove the six 3/32" screws marked with red circles using a JIS #00 screwdriver.
• Remove the larger 3/32" screw indicated by an orange circle using a JIS #1 screwdriver.
• Once the screws are removed, gently lift the top (where the touch controls are) off of the speaker.
Step 8
• De-solder the connections from the battery to the circuit board.
• If you do not already have a replacement battery, you can purchase one here.
Step 9 Motherboard
• Follow the steps leading up to the actual battery removal, but do not actually remove the battery.
• Remove the two 3/32" screws that attach the motherboard to the battery compartment using a JIS #00 screwdriver.
• Use your fingers or a pair of tweezers to remove the clip holding the ribbon connector in place. The connector is indicated with an orange marker.
• Be sure not to apply excessive force on the ribbon connector, as it can break.
• Find the speaker connector, indicated by a yellow circle, and using your fingers disconnect it.
Step 10
• Locate and remove the two 3/32" screws, indicated by red markers, that fix the motherboard to the speaker enclosure.
Step 11
• Using the plastic opening tool, gently begin to pry the circuit card away from the speaker enclosure.
• There is adhesive on the top of the motherboard, use caution while prying to avoid breakage.
• Using your fingers, you can now remove the motherboard.
