I have had this tv for about 2 1/2 years and tonight the tv started making this loud humming noise from the back of the tv. The picture was a little off colored and slightly blurry. After I turn the tv off, I can see a small fan in the middle of the tv still going but the noise stops. Does someone know if that would be the color wheel or one of the two fans that Samsungs website says it could be? Thanks
