  • Is your LCD making a buzzing or high pitch noise

    Dec 30, 20080183;32;But then started making a buzzing noise 1) when on, 2) worse when in power stand by mode, and 3) even worse when turned off. Thanks Dell It seems as if the cheap capacitors manufacturers use in these LCDs, after a while, start to resonate at a high pitch frequency that is very annoying in a quiet room.
