In this guide, you will learn how to replace the LED lights that are located on either side of the Treblab HD77. These LED lights indicate the current status of connectivity for the speaker and as a result are very helpful in using the speaker effectively. This guide aims to teach you how to replace these lights in the event that they stop working.
Note that this speaker is water resistant and as a result uses a water resistant adhesive in some areas which will have to be removed in certain areas in order to access the LEDs. To restore its water resistance, this adhesive will need to be manually reapplied before reassembling the speaker.
Make sure the device is powered off before disassembly.
