I recently fixed two monitors which use the same power board as the Hanns-g HG281D (power board PSM217-404-h-r).
Both monitors now make a slight buzzing sound when they turn on. The sound becomes a higher pitch when they are turned off (in standby mode). The sound seems to come from the component on the left of C701 (image taken from big HG281D thread).
The monitors don't have any other problems. Is this a normal noise?
