Introduction
This guide will walk you through the process of accessing and cleaning the charging port on your JBL Tune 760NC headphones. If you're experiencing charging issues, intermittent power, or a loose cable connection, debris or oxidation inside the charging port may be to blame. Carefully cleaning the port can often restore proper functionality without replacing any components.
Before You Begin:
Make sure the headphones are completely powered off and unplugged. This process involves opening the right ear cup and accessing the motherboard.
-
-
Locate the charging port on the outside of the right ear cup.
-
-
-
Place the headphones on a stable, flat surface.
-
Insert the Jimmy pry tool at a 30° angle into the seam between the ear cup and the plastic cap.
-
Pry gently but firmly to release the internal clips. You may need to try different spots around the seam for easier access.
-
Once the cap is removed, set it aside.
-
Reminder: Keep track of any small plastic clips or parts that may come loose during prying.
-
-
-
-
Once you have successfully removed the ear cap, locate the two screws on the motherboard.
-
Using the Phillips #0 screw driver, gently remove the silver screws and place into a safe storage container.
-
note: be careful not to lose the screws as you will need to screw back on when finished.
-
-
-
Once the screws are removed, carefully lift the mother board out of the socket.
-
Once removed, use a flashlight, inspect the port for any lint, dust, or damage. You may see buildup around the inner pins or edges of the port.
-
Use a soft brush or compressed air to remove loose debris.
-
Dip a toothpick or brush in a tiny bit of isopropyl alcohol and gently clean inside the port.
-
Gently scrape out any any buildup, being careful not to damage the internal pins.
-
Let the port fully dry if used isopropyl.
-
-
-
Carefully close the right ear cup, ensure all wires are tucked in and not pinched. Snap the casing back together securely.
-
Plug in your charger and check to see if the headphones begin charging.
-
If your JBL Tune 760NC headphones now charge properly, your cleaning was successful. If not, the issue may be with the port’s internal connection or the charging cable itself. Consider testing with a different charger or seeking further repair assistance.
