No picture


It's obvious that the power supply failed. The most common parts in a power supply are a thermistor or a voltage rectifier, possibly even a voltage regulator. diodes or resistors can act as fuses too. A ringing sound can come from a fixed coil that isn't kept still with enough epoxy. Hope this helps.

Have just bought an LG37LD450. Buzzing noise coming from the components at the back of the TV. Annoying. Otherwise TV perfect. Definitely not sound problems because buzzing noise still there when on Mute....


Had this problem as well. Ran through a laundry list of possible solutions. Finally found that the key is to increase the backlight (Access via [Menu] [Picture] ) to 100% and the noise goes away. If this is bad for the life of the backlight, just pray the backlight burns out inside year 1 while the warranty is still valid!
