Hi,do you hear buzzing ,whirling,or high pitch sounds?If you do it could be an issue with the color wheel.The Samsung BP96-00674A color wheels spin anywhere from 6,000 to 15,000 revolutions per minute (RPM’s)--It is one of the few consumable parts in your Samsung TV. The average life expectancy from our data logging shows the Samsung color wheels are fairly reliable with a MEAN average of 5-8 years But it could also be the Dmd board this is how it works: http://electronics.howstuffworks.com/dlp1.htm Baisclly the DMD board creates the images and colors through its chip that has 2 million pixels,when that chips goes out you'll see either lines ,pixelation and dicoloration.One simple way to see if it is the Dmd its to display menu if it's also appears distorted that will be what it is.
