Hi,it definetely sounds like the color wheel.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.Found your color wheel here: http://www.discount-merchant.com/MITSUBISHI-00-L3603-002-p/1162430.htm Have a bless one!
Turn the color level all the way down and see if you have a good black and white picture. If your screen isnt black and white it should have a predominate tint to it. then turn the screen control for that color down to achieve the best black and white picture. then adjust your color level that should help.
Like your computer a tv has the same type of circuits, & sometimes they get glitches, maybe, but i feel you might be starting to have a problem in the 'DMD" board in your tv. Maybe not; unplug tv for 10 min to 24 hrs. I am a mit factory auth tech. good luck,.
