Samsung DLP makes a moaning sound; has no picture

[psmiles]

My 61" Samsung DLP is 7 years old. It won't come on now (no picture) and makes this moaning sound like a sick airplane on descent. Any ideas what the problem is?

I have found the 3 times I had to replace color wheels that they made a moaning or vibration type sound because color wheel was defective due to wheel coming apart. The unit when hand on back side you could feel vibration which I found it was the color wheel. I found it was actually very easy to replace, take your time take pictures if you have to, and do not be afraid to ask question if you do run into a problem.
