Can I break my monitor's LED? (lemy.lol)

I own a Samsung monitor, and when it's in standby mode the LED blinks all night. My hearing is so sensitive, and my room so quiet, that I can actually hear the LED powering on and off.

So, every night I power it off manually. Sometimes I forget as I turn my PC off, and as I'm laying comfortably in bed, falling asleep, I hear it cycling, so I have to get out of bed, walk over, and turn it off, which delays my sleep.

At this point I'm tempted to take off the bottom panel and break the LED with a screwdriver, but I'm worried that this might change how the current flows through the monitor's circuit board.

I would appreciate any advice, suggestions or insights, thanks in advance!

Did you stop reading the post after the first sentence?

Putty can block sound if it's covering the thing emitting that sound? The visual parts were just there because it might be unsightly

I genuinely cannot believe this shit.

IT FUCKING WORKED!

Giant blob of Blu Tack over the light and the sound is in-audiable.

You're a fucking legend, love you forever.

I'll give it a go, no harm in trying. Though, my intuition tells me the frequency of the sound will emit through the plastic covering the front.

covering the thing emitting that sound

You're implying that the LED itself is emitting sound. Obviously that's not the case. Not that covering one side of an isotropic sound source would even mute it
