Screen shows only black and white
So, we just got this TV serviced about two weeks ago, because it wouldnt turn on. Now, as of today, it only has a black and white picture! On top of this there is a fairly loud humming coming from the back of the TV? It makes no sense to me. I have read from a few post that it could be the color wheel..?? But why the humming noise? the TV is only five years old, and for the price we paid, it should be lasting much longer than that! Does anyone have any ideas?Thanks

Color wheels do go bad quite frequently, if you got 5 years out of the original, believe me, that's good.
The color wheel is attached be a bearing, like a fan and when the bearing starts to ware out the color wheel on the shaft starts to wobble and that's what you hear, they spin I believe around 3000rpm. Try contacting your servicer again, don't be mad, maybe he'll be kind enough just to charge you for the color wheel. I'm sorry, but that's the best advice I can give you..Good Luck...
