My Samsung has had a loud buzzing sound for a few weeks now, and over the past 3-4 days, it has been in black and white at times. Now, there is no picture, just sound only. I have read blogs where people...


The noise you heard was the Color Wheel going bad. This part acts the same way as the large color wheels people use at christmas time for changing colors on there trees, house, etc. They do the same thing in a dlp set except spin a whole lot faster and combined with the Digital Light Processor it gives you your primary colors. If the speed starts to slow down because of the bearing going bad then you will start to notice a B&W picture and the noise. Eventually the picture will not come on because the Microprocessor has detected an error and will not let the end process start.So, there we have it. Have a tech verify this and see if the Color Wheel is still available as a single unit or complete with the Light Engine which in that case would not be worth repairing.

After much research, it became apparent that the most logical culprit after the lamp was the color wheel. It has been replaced and the set is working again.

Loud humming or buzzing when set is in operation


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.
