The whole process will take you 5-10 minutes but will require very basic soldering skills.

Start by flipping the charger to reveal its underside. You’ll see four rubber stands—remove these using a screwdriver.

Figure 1.

Beneath each stand, there’s a screw. Unscrew each one to proceed.

Flip the charger back over and gently pry off the cover. The plastic is durable, so you're unlikely to cause any damage.

After taking off the cover you will see a few circuit boards

Figure 6.

With the cover off, you'll find several circuit boards inside. Locate the board that matches the image provided; it contains the problematic speaker marked as 'BUZ1' (red arrow). To access the speaker, remove two screws holding the circuit board in place, as indicated by the blue arrows in the image.

Figure 7.

Beneath the board, you’ll find two pins connected to the speaker. Unsolder these pins to detach the speaker from the board.

Once the speaker is removed, reassemble the charger by following these steps in reverse order.

Congratulations! You can now enjoy your Samsung UV charger without any disruptive beeping. 🎉
