Picture failure Tv will not work. While watching tv color would sometimes fade in and out. During the last couple of days the picture would come in but the screen would turn green and picture disappears, also tv would somtimes turn off. Now screen is just green and you see no picture or not very clear at all.

I have a Samsung rear projection tv, the picture is faded and the colors are not crisp or clean cannot watch it like this what do you think the problem is?

If this is a CRT-type rear-projection TV, the CRT coolant fluid is probably broken down. It's supposed to be clear, but after a long period of TV operation, it turns a yellow-brown color. If you unplug the TV and remove the back, you can look into the tops of the three picture tubes. They should be a clear red, green or blue color, with no yellow-brown tint.

CRT coolant can be changed, but you need to be very good at mechanical work to do it. Besides the safety considerations (picture tubes and other parts may carry a high voltage charge even when the set is unplugged), spilling broken-down coolant on electronics is usually disastrous, so you have to be very careful.

LCD panels used in projector applications may lose contrast if they are overheated (this can be caused by failure to keep the vents clean as recommended in the owner's manual).

You would have to provide your set's model number to get more specific information.

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.
