Average life on a OEM lamp unit is 2,000 hours which usually works out
to 2 years (unless you use it a awful lot of hours).Bad color wheels in
these sets usually exhibit a high pitched sound or fan like noise--even
heard a few that sound like a garbage disposal.The wheel faces the lamp
so if you can remove the lamp and look at it to see if shattered or
missing pieces.Someone posted instructions for the replacement
online--let me know as it is on my bookmark list now.Only way to know
(other than taking lamp out and finding it shattered inside) is to
replace it.May be the lamp again, maybe the Ballast that drives it etc,
kind of like starter on car turns but car will not start.Try to look at
turn on to see if lamp even fires for a moment--then inspect color wheel
etc. If you want the URL for the installation of the wheel let me
Usually a bad color wheel will produce a high pitched sound or even a
grinding noise; some sets may actually shut down if the wheel is bad or
To determine if you have a bad color wheel:
Turn set off and wait for main fan to shut off.
Unplug the set.
Remove the lamp door and then remove the lamp.
In the direction the lamp faces you will see a round opening; the color wheel is facing this opening.It
is a round plastic wheel with colored segments—we want to look to see
if any of the segments are missing; a shattered wheel should be clear
I have also posted the general instructions for Do it yourself replacement of this part in the TIPS AND TRICKS section of this site.
I will attach a photo of the color wheel for you to know what you are looking for----

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.
You may not see any deterioration in the picture when the color wheel begins to go bad. The noise will get louder and eventually, it will shut down or the wheel will shatter while the motor continues to spin. If that happens, you'll have a black and white picture.
If its a Samsung DLP that is mercury vapor lamp driven, its a safe bet the color wheel is going bad.
That was probably your color wheel being destroyed. This repair is not for the DIY'er you need to see a tech for thione believe me... The light engine housing needs to be removed justy above the color wheel and a new color wheel needs to be installed. Wheels are not cheap 2-3 hundred dollars and you would be surprised how much tear-down the tech will have to do to get at the wheel housing. But believe me it's well worth it...
If you have any problem locating a good reputable tech for the repair you might try NESDA (National Electronic Service Dealers Assn.) or let me know about what city/state you're located in and I can recommend someone.
If it is it will be the first I've heard of one shattering... The CW spins at 7200 rpms and at that speed anything is possible. What color is the glass?? Clear and it's not the CW.. My bet is on the lamp. Does the lamp fire up?? You need to do a bit of investigating and let me know and I'll try and help..
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.
