This sounds to me like one of two possibilities. First, check your ballast. If you're going through bulbs faster than you think you ought to be, you may have a ballast that is overloading. Its the 3" x 8" circuit board that connects directly to the bulb. They are plentiful and often cheap. Thats what I'd try first. If that doesnt' do it, I would invest in a new power supply board. That the board that the tv power cable hooks directly in to. This should give you a start, Comment back if you still need further help. Good luck.

Hi,

Samsung is known for bad color wheels and for what you describe it surely sounds like the color wheel bearing if going out on you,you will need to replace the color wheel you can find more help @ fixyourdlp.com and if you want to buy the part you can find it @ http://www.discount-merchant.com/SearchResults.asp?Search=color%20wheel?click=52978 or @ http://www.samsungparts.com/search/search.asp , just so you can be 100% sure you will need to get the part number from the actual color wheel that you already have,
