Assuming the noise is a high-pitched whine, then yes, it is the color wheel.  If the color wheel goes out, the TV will turn on for a while, then turn off when it can't establish color wheel sync.  The color wheel has to be in sync with the mirrors on the DLP, so if sync can't be established, the TV turns off.
You can order a new color wheel from Sears or partstore.com (among other places) and replace it yourself, if you are so inclined.
