For additional technical references, you may review the model documentation available on manualslibraryy.com.

Step 1 — Power & Safety Check

• Turn off the speaker and disconnect any charging cable.
• If the device recently overheated, let it cool before opening.
• Wipe off moisture or debris to prevent damage during disassembly.

Step 2 — Remove the End Caps

• Use a plastic pry tool to gently separate the rubberised end caps.
• Work slowly around the edges—JBL uses strong adhesive, so steady pressure helps.
• Set the end caps aside once both sides are free.

Step 3 — Unscrew the Housing

• Using a Torx T6 or T8 driver, remove the screws holding the external shell together.
• Keep screws organised as lengths vary.
• Slide the outer panel away to reveal the internal components.

Step 4 — Disconnect the Battery

• Before touching any internal part, locate the battery plug.
• Use a spudger to disconnect the battery connector from the motherboard.
• Inspect the battery for swelling, leakage, or a burnt smell.
• If damaged, stop and replace the battery before continuing.

Step 5 — Inspect the Charging Port

• Common issue: Charge 5 not charging or charging intermittently
• Locate the USB-C port module.
• Check for debris—clean gently with a dry brush.
• Look for broken solder joints or bent pins.
• If the port wiggles loosely, it may need resoldering or replacement.

Step 6 — Check the Passive Radiators

• Common issue: Buzzing or rattling sound
• Inspect both side passive radiators for tears.
• Ensure each radiator is firmly seated and screws are tight.
• Loose radiators can cause distortion; tighten carefully.

Step 7 — Clean the Buttons and Contacts

• Common issue: Power or Bluetooth button not responding
• Gently remove the rubber button strip.
• Clean the underlying contacts with a cotton swab dipped in isopropyl alcohol.
• Reinstall once dry.

Step 8 — Speaker Driver Check

• Common issue: Distorted audio or no sound
• Inspect the main driver for visible damage.
• Check its connectors to ensure no wires have loosened.
• If the driver looks burned or torn, it may need replacement.

Step 9 — Reassemble the Unit

• Reconnect the battery.
• Carefully close the housing and reinstall all Torx screws.
• Reattach the end caps by pressing them firmly back into place.
• Test the speaker before fully securing the final components.
