Popping noise


Apr 11, 2012
I have a catleap monitor, which is very nice - visually. However after many weeks of searching for the source, I finally tonight tracked a strange 'popping' noise to originate from my monitor. It's not particularly loud, indeed that's why it took me so long to track.

It originates from the left-hand side of the bezel at the bottom of the monitor.

Anyway, here's an mp3 of it being recorded from about 10 cm away (dropbox). The second click is my mouse ending the recording.

Does anyone have any idea what might be causing this?

Thank you.
