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.

Turn on TV hear a buzzing and then the TV cycles off and on again


Hi,If it seems you are experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.I found it with complete light engine assembly here: http://www.discount-merchant.com/TOSHIBA-2973026206-p/1160068.htm?Click=48173

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

Loud buzzing noise which became a very loud screech over the last week. Turning tv off and on seemed to remedy it. Today screen was only black and white, now no video only audio. Is this the picture...


This TV uses a lamp and color wheel. the color wheel is likely the problem since it is known to make noise over time and will eventually sieze. The repair is in the $400 range.

Black and white picture only


The color wheel is not the problem. If the spinning color wheel is impaired in its RPMs it will cause picture distortion, not black and white picture. If the color wheel looses any of its color fins, like if it is broken, there will be a loud vibrating noise inside the tv which you did not mention. Also if the color wheel is broken and doesn't spin, the tv will not start up.

The likely problem is on the digital control board or the power supply and should be referred to a local repair shop for repair.

There is an outside chance that you will receive color if you experiment with using all of the different input ports to see if you can find one that will bring back color.
