JVC TV making buzzing noise

A few weeks ago, the TV started making a buzzing noise when we turned it on, but the noise would stop after a minute or two. Now it buzzes intermittently any time the TV is on, even if the sound is muted. Any idea what's causing this or how to fix it or how much it would cost to have it repaired?

SOURCE: Buzzing Noise and TV picture is yellow

Andy, I'm thinking the buzz is from the deflection coil (yoke) on the neck of the tube or the power supply. Probably not the high voltage as you can hear the "buzz". If it's really that annoying, you can take a length of rubber tubing (no metal) and listen to the buzz coming from the chassis kind of like a stethoscope. STAY AWAY FROM THE HIGH VOLTAGE, please. The yellow picture sounds like a blue chroma failure. A tube can be rejuvinated if need be but that's a job for a pro. Hope this helps.

Highly likely that the sound was coming from the bearing in the color wheel assembly. When the bearing fails, the color wheel cannot spin at the correct speed, and because the speed is measured by the control board, the TV will shut down.

If you can handle a screwdriver - entire color wheel assembly can be replaced for about $100 and 30 minutes of your time.

Very louud buzzing from LG LCD TV 42lg50


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Loud buzzing noise when turning on


It sounds like a bad internal connection or a component failing. If the picture still is very good take it to a known good repair shop.

Refrigerator buzzing for 10 seconds every 4 or 5 minutes


Buzzing is usually a fan, like one in the freezer, or back bottom - for cooling the freon. The compressor over-heat usually will make a single click (off) and a few minutes later a click (on). If the fan in the freezer stops working well, the freezer will frost up and the fridge section will not be cold enough.
