Question about Projection Televisions
The color wheel can make a whinning sound for sure, However it should not continue to whine after shutting it off. That sounds more like the fan used to cool the lamp, as that will continue to run after the set is shut off. How soon does the whinning start when you push power? Let me know I should be able to help you out. DLPs are my specialty

SOURCE: WHINING SOUND
More likely it is the color wheel this set uses---it is located inside the optical engine---part number for it:
267888This part is no longer available from RCA but is available on several sites on the internet (google the part number)
The wheel will when going bad sometimes make a fan like noise or even a high pitched whine.
Check out the sites on the net that sell this for price and decide if you want to attempt to replace it or if you have to have a shop do it for you.
Let me know if you have any questions or need advice.
REGARDS, SD TECH
