转到步骤 1

This guide shows the necessary steps for removing the mother board from a DOSS SoundBox.

This motherboard controls the connection between Bluetooth and Auxiliary devices so signals transmitted by Bluetooth or Auxiliary can be processed and played over the loudspeakers. If the motherboard fails in the DOSS SoundBox, diagnostic symptoms can include static, intermittent connection issues or failure to play music.

Minimal knowledge is required for soldering as uninstalling the motherboard requires two contacts to be unsoldered.

There is also some adhesive holding the motherboard in place, so caution is recommended during removal to prevent breaks or cracks.
