Hey, first thing that comes to mind is that your cables are faulty.

OR

your receaver (or what your tv is connected to) Is causeing the buzz.

My Samsung HL-S5065W will turn on, it makes a humming noise. The picture comes on after a 1 minute or so the screen will go black and the tv shuts down. What could this be?

experimenting a color wheel problem.The

color wheel is a rotating disc that has a

gamma of colors it spins at high rpms.The

light of the lamp goes through it to create

the colors on your tv.When it starts to go

bad you will hear ,humming,buzzing,high

pitch noises ,you might also experiment

color distortion ,black and white

picture.Here's a link that will help you

replace it:

A high pitched tone is constant when the TV is on


The problem could be that of coil that has become loose and is vibrarating cause your squeal . Or it may be a transformer in the power supply that is also vibrating . These can only be replaced to get rid of your problem and you have to isolate which one is causing the noise . Good luck

Sony Bravia LCD T.V.


It is most likely a fan (there are 2 to 3 of them in the set) that is making the noise. I doubt seriously that the lamp is causing a buzzing noise. The only other buzzing sound can come from the ballast wich powers the lamp.
