Question about LG RZ-37LZ30 37 in. LCD Television

1 Answer

Sound problem Hi, I'm having trouble with the sound on my TV. It seems to have a high pitch background noise that has been getting progressively worse. The noise is even there when the TV is on mute. I've had it just over a year and this noise wasn't there when I first had it. It has moved house so not sure if it's a connection problem. Hope you can help as this noise is getting really annoying! Thanks

Hello
The LOT [Line Output Transformer] of your TV has damaged. It is the one, that supply all the voltaged needed to CRT. Its internal windings will get shorted in between, and is irreparable. Replacement is the only remedy to this proble. Replace the horizontal output transistor also with this. you haven't specified whether there is picture with your tV or not. If this high frequency sound is along with picture, there is some loose in the cores of the SMPS transformer, or LOT itsef. If there is no picture at all, and this high frequency sound is there, no doubt; LOT is damaged. OK.

High pitch sound in background

A high pitch sound while connected in the house is either a problem with the reciever or you are picking up interference from somewhere. However, the high pitched noise when using the unit in a car (especially through an aux. connection), is caused by the alternator of the car. This can be eliminated by connecting a filter in-line with the aux wire (much like filters are installed on the radio power line). The filter is essentially a low pass filter that filters out noise above a certain frequency. You may have to get creative and modify your aux. input cable (i.e. - splice it into the aux cable) in order for this to work, or you can just turn the volume down a bit - it should be less noticeable at lower volumes.

Weird noise over everything

According to the Samsung website: "The high pitched sound you hear is probably coming from the flyback transformer. The flyback transformer converts the relatively low voltage electricity that comes from the outlet in your home to the high voltage electricity needed to drive the cathode ray tube in your TV. It is not unusual for a flyback transformer to buzz softly when it operates. However, if the sound is loud and high pitched, it probably means the transformer is failing. To eliminate the sound, you will have to get your TV serviced."

High Pitched Noise

most high pitch noise comes from the anode conection on the picture tube thats connected to the flyback anode cap thats mean there is a high voltage leak,to stop the noise you can discharge the high voltage take off the cap and clean with alcohol.if the noise continue.you will have to put some red or clear silicone both the cap and tube stick together leave to dry for about 2 to 4 hrs.this will eliminate the leaking.good luck.
