Buzzing noise from lamp area.

If the buzzing noise sounds like a fork in the microwave, it's time for a new lamp. If it sounds like a squealing noise, it's either a fan or the color wheel. Color wheels are not easy to replace, so I recommend hiring a Service Tech.

The colors wheel was defective,was spinning off of it axis that was where the buzzing noise came from.Now the colors wheel it totally dead,that why u not hearing anymore buzzing noise,and not getting a picture.Hire a tv repairman for this job.Replacing DLP tvs colors wheel is not easy,if u have no machanical's skills and never done this before.

First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.

The Lamp probably is bad but it going bad would not cause a buzzing sound. I have a hunch that the Color Wheel Motor is bad causing the buzzing noise. It is a major repair and the cost would be expensive. But this is the deal, you will need to get a qualified repair person out to confirm the symptom to be sure. You can go ahead and replace the Lamp to get the set working again and use it for as long as you can stand the buzzing noise. If it is the Color Wheel Motor, I would check prices on replacement sets just to get a feel of how much you are willing to spend for repairs.
I hope this helps,

Does the picture gets distorted in any way when you hear the buzzing noise?
I would suggest to check all the cooling fans for proper operation.

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

buzzing from the lamp area could be either the fan or color wheel Whats the model number of your set, and I can better answer your question

If you hear a ticking and or buzzing sound as it is trying to start up then most likely the replacement lamp is bad. Take it out and reseat it one more time to see what happens. The noise you hear is the ballast attempting to fire the lamp up.

since you changed the lamp my next thought is that the color wheel has failed,,,most good road techs can replace it in the home..the cost would be between 220.00 and 350,00 depending on the company...

Yes,it sounds like the color wheel motor is going,and yes it satais on untill lamp cools down
