Samsung Big screen mod. HL-P6163W made load pop, then buzzing sound with screen going to black and white. Make buzzing sound and no picture when turned back on?


This set has a problem with the color wheel falling apart, which if one of the segments should fly off while the set was on it may sound like a loud pop, and the buzzing sound could be mechanical in nature with the wheel being off balance. If smoke appeared after the loud pop, then it could be a capacitor blowing in the power or video circuits. This model uses two different types of Color Wheel assemblies, either an L3 or a L6 and it would be listed on a white label on the Light Engines metal frame. Hope your solution is this easy.

Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner.

Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Screen went B&W and I hear a loud humming noise from the TV...


Hi John,

If you are hearing this noises,that's your Color Wheel.
The reason fot that is because your color wheel spins 5000rpms(revolution per minute) and something that modifies the balance if the disc can cause different things.Unfortunately in order to check if your color wheel is working properly you need to open your TV and physically check out.

Grinding= Most probably the color disc is broken and you need to replace it.

Spinning / Buzzing = The bearing of the wheel is loose and is loosing its balance,eventually it will brake.

The best thing to do is to take the color wheel out and spin it ,if you feel that the disc kind of wobbles or doesn't spin smoothly you have to replace it.

You can check DM they have very good prices
