Introduction

Unfortunately, the buzzer is soldered on the display’s mainboard so it requires a bit of work to take the whole thing apart and unsolder the noisy component.

Do this at your own risk!

This will most likely void your warranty!

Step 1

              Remove the Top Screws
  • Take out the water tank
  • Remove the 7 screw covers using a flat screwdriver/sharp blade
  • Remove the 7 screws using a Phillips screw driver
