You have a bad tuner or there is a capacitor bad in the color burst circuit.

You need to take out the DMD bord and open it up then remove the DLP Chip very carefully and blow out under the chip and all the components in the box with dry air something with a dryer on it then reassemble the chip on to the bord and make sure that the three screws that holds the mount that houses the chip are snug then you will need to put the Bord back in and have someone Else watch the pitcher so you can center the pitcher. This happened to me with my samsung tv and ran across this in sum service notes for this problem. Hope this helps

SOURCE: There is no color and a very loud noise comes from

Sounds like your color wheel has failed. Its right about time, they don't always go bad but do fail regularly. This one uses a bp96-00250a and it costs about $95 plus shipping. You can get one straight from samsung it will come to about $105 after shipping.

Its a little tricky to get it in, and its glass so its fragile, but a mechanical person with a few screwdrivers can get it done in an hour or two. Let me know if I can be of further assistance.

This is unusual for this model, can you tell me what source you use for signal? Cable? Sat? Direct TV? Also how are you connected----via the coax fitting or the rear AV jacks.

This tv have a colors wheel design in it.The tv make loud grinding motor noises or pictures flashes or freeze and pictures turn in black&white with sound.The tv colors wheel it is dying or worn out already.Don't tries to change the tv colors wheel ur self.If u don't any mechanical skills,because the colors wheel it sit way back of the tv,must take out many mechanical parts before even can come to the tv colors wheel itself to replace it.Best to hire a tv tech. to change the colors wheel,so no problems for tv funstions for later or damages more parts on the tv set,if u install the new colors wheel in the tv wrong way.
