sounds like you need a service call if it's in warranty, if not in warranty, you may need to have the logic main board replaced

SOURCE: I have no color on my Samsung Flatscreen TV

Hello,

This means absolutely no color - equivalent to a black and white picture. Not even a hint of color.

First, confirm that the source is actually in color - try another channel or input device.

Next, check the settings of the color control - it may have accidentally been turned down. If your TV has some kind of automatic picture mode, try turning if off and adjusting the color control. Try adjusting fine tuning if you have such a control and the problem is with a broadcast or cable transmission.

At this point with a confirmed color signal source, there is a problem with the chroma circuitry.

Note that to the average person, the obvious question becomes: is my color picture tube bad? The answer is a definitive NO. It is virtually impossible for a defective CRT to cause a total loss of color. A defective CRT can cause a lack of a primary color - R, G, or, B or a short between two colors which will mess up the color but is not likely to result in a black and white picture.

Some possibilities in no particular order:

Weak signal or defect in tuner/IF causing loss of signal strength.

Coler killer set too high (internal control) if it has one.

Defective part around the chroma chip/circuit. Faulty color oscillator.

Bad connections in area of chroma chip/circuit.

Defective chroma chip (don't suspect this first just because it is probably very expensive).

Try prodding the main board around the chroma chip with an insulated tool to see if you can make the color come and go.

I had one set where a $.02 resistor decided to open up causing just this problem - perfect BW picture, no color. Another had a coil with a broken wire.

Black and white screen...


The color wheel can cause a black and white picture but not the jumpy or negative look.
Those symptoms are usually caused by the DMD assy which drives the color wheel and is somewhat expensive, most of the time you can purchase the whole Light Engine which includes the DMD assy for the same price.

Our Color TV is now Black & White


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.
