My Samsung HLP4663W 46 in was making a buzzing noise for several months. I know it could have been either the fan(s) or the color wheel, but I never opened it up to determine which it was. Now the TV quit...


Great reasoning work! In fact, the lamp will not light if the color wheel does not spin-up. Fans will not stop the process of lamp ignition. Instead, a fan will be detected and a message will appear on the screen telling which fan has stopped. You need to have the color wheel replaced.

I have just inherited a samsung HLP4663W, It had a color wheel that was making noise. I have replaced the color wheel. Now I am getting a fan speed warning. it will come on but shut off after approximatley...


You have 4 different fans inside of your TV. The biggest challenge - to pinpoint which one is bad. I would recommend just to get 'em all and replace 'em all. They will start fail one after another anyway.

Your color wheel has gone bad. I recommend this repair to only be done by a qualified Samsung service center. Part costs less than $100
