LED noise is not due to something vibrating. Former Sound Engineer and well LEDs make noise (super quiet). My guess it is the transformer that is making the noise since a LED powered monitor is regulating the voltage of the LED as needed if it didn't do that your power use would be many times higher than with a voltage regulating transformer. Wouldn't mean anything damaging is happening at all.
