Humming noise

There are only two moving parts in this set. The fans and the color wheel. Typically when the color wheel starts to break or go on the fritz, the tv stops working. Count your blessings you've still got the picture. Open the back and turn the tv on. The color wheel is located on the optics block tray. The fans are very visible with the back off. Stop the fan for a second and see if the sound goes away. If not, you might want to start looking around for a replacement color wheel. is a good place to start. Sometimes carries them too. Be aware that there two different wheels available. If the fan is the culprit of your problem. Radioshack will likely have a replacement for you. If you need further help, post a comment or email me and I'll send you pictures of what to look for.
Good luck.

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.
