Since you have replaced the Color Wheel, it sounds like you have not adjusted the Index Delay in the service menu. First reset all of the picture settings you have adjusted back to original factory settings. Then on your Samsung TV Remote and with the TV OFF, Press Mute,Power,123. This will turn on the set and put you in the Service menu. Look for the top setting and select or scroll to the OPTION setting and select and look for INDEX DELAY and select that. Once you have the Index Delay selected use the right and left buttons on the remote to adjust for a picture the has no abnormal coloring and while looking at a program adjust for when the blacks look black with no abnormal coloring. Once that is done, turn off the set then turn the set back on. Now the picture should look normal.
Samsung's digital light projection (DLP) televisions use a spinning color wheel to create the colors that are seen on the screen. If the color wheel becomes misaligned during use, it will become damaged and have to be replaced. Replacing the color wheel on a Samsung DLP television can be done at home, once a compatible-sized color wheel has been bought from a TV supply store.Replacing the color wheel yourself will void any Samsung warranty that might be in place, but is the only solution for getting the TV working again in as short a time as possible.
Put on the anti-static grounding strap to keep static electricity from damaging the internal components of the Samsung DLP TV. Turn the Samsung around so that the back is facing you. Make sure the Samsung is unplugged from the AC socket.
2 Use the Phillips screwdriver to remove all of the screws from the back panel. Put the screws aside. Pull off the back panel.
3 Loosen the two screws from each side of the projection bulb's case. Pull the projection bulb out. Put the projection bulb aside. Use the Phillips screwdriver to remove the two screws from the left side panel. Pull the side panel and the circuit board attached to it out carefully and put it down so that the cables attached to it have not been pulled out.
4 Take a picture of the power cable's position with the digital camera so that you can put it back correctly later. Pull the power cable out from inside of the Samsung's case so that the center panel is free to be pulled out. Remove the two large headed screws from the center panel with the Phillips screwdriver. Remove the top two screws holding the panel to the plastic case using the Phillips screwdriver.
5 Slowly slide the center unit out a few inches. Take a picture of the projector lens' positioning with the digital camera so that you can put it back correctly later. Unplug the two cables from the left side of the center panel. Unscrew the sensor switch using the Phillips screwdriver. Slide the center panel completely out of the Samsung and put it down on the clean cloth. Blow off the color wheel assembly with the compressed air.
6 Use the tweezers to remove the green plug from the top of the color wheel cover. Use the tweezers to remove the two cables at the side that are coming from the color wheel. Use the Phillips jeweler's screwdriver to remove the screws from the top, front and back of the color wheel cover. Slide the color wheel cover straight up to expose the color wheel.
7 Use the Phillips screwdriver to remove the three screws holding the color wheel to the color wheel assembly. Lift the color wheel up and out of the color wheel assembly and discard it.
8 Position the replacement color wheel in the color wheel assembly. Reassemble the color wheel and reassemble the color wheel assembly. Put the color wheel assembly back into position in the rear of the Samsung DLP TV. Reassemble the Samsung DLP TV. Plug the Samsung DLP TV back in for power. Turn the Samsung on and enjoy seeing the colors displayed properly again now that you have replaced the color wheel.
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.
It could be the color wheel and in fact probably is. I've seen them shatter which would explain the noise. They are glass and spinn at 9000 rpm. An involved repair though definatley a job for a pro. It could be worse, probably a few hundred will do it. Was the TV begining to be a little loud before the failure? Could be a sign, i've seen many noisy color wheels.
The color wheel is the most common problem in DLPs that cause noise.
To determine the cause:
Turn the set off.
If the noise goes away after about five seconds, then, the problem is the color wheel.
If the noise goes away one to two minutes after shut off, then, the problem is a fan.
