Buzzing loud noise constantly.

Buzzing is a cue that the transformer windings are loose. Time to replace it if you want silence.

Problem is the Color Wheel PN#212184 Model HDLP61W151yx1
Look on Ebay-under Electronics TV/Parts type in Part Number.

mine does the same exact thing nothing fixes it, it only goes away after the tv warms up

If it is a buzzing noise, it is the Ballast for the lamp.
If it is more of a grinding sound, it is the Color Wheel motor.
Does it go away when you turn off the tv? If so, does it stop abruptly or does the sound tend to get softer (winding down noise)
If the noise stops abruptly it is probably the Ballast.
If the noise takes several seconds and seems to get softer until it stops about 30 sec later then it is the color wheel motor.

There are only 2 moving parts on a dlp tv the color wheel and the fan. The color wheel needs to be replaced about every 4 to 5 years. Some start to make noise and others like mine blow up with a bang. Go to utube to get instructions on how to replace it only cost me for part $100 good luck

it's the colour wheel,i have replaced it once under warranty and now need another, rca and dlp ****

sounds like the color wheel needs to be replaced very easy repair on that model Samsung.

I would have to have your full model number in order to help you with your problem.

Set has a defective color wheel. This needs to be replaced and your tv will go back to normal.

It sounds as if the lamp needs to be replaced. The buzzing sound you hear is the ballast attemting to fire the lamp.
