• sounds like a pixel has gone... not good. Not a lot you can do. I've had it on a monitor or two. Bummer :-(
  • 'Hot' pixel yo... Stuck pixels, unlike dead pixels, have been reported to disappear, and there are several popular methods purported to fix them, such as gently rubbing the screen (in an attempt to reset the pixel), cycling the color value of the stuck pixel rapidly (in other words, flashing bright colors on the screen,) or simply tolerating the stuck pixel until it disappears (which can take anywhere from a day to years.) While these methods can work on some stuck pixels others cannot be fixed by the above methods. Also some stuck pixels will reappear after being fixed if the screen is left off for several hours. -WIK yo... Read up yo...
  • may be dust on the screen or optic lense - check the cabinet side for round access holes, held with one screw. have someone put a finger over the spot and look at the back of the screen - use a VERY soft cloth or feather duster to remove
  • Rubbing the screen will not work on a DLP display, since the pixels are nowhere near the screen. The pixel is on the micromirror chip and light is reflected off of it onto the screen. Seems like cycling might have a chance to fix it, but unlikely. What you have there is a stuck micromirror. It's stuck in the on position and is reflecting RGB full time and is therefore a bright white pixel. A sure fix for this would be to replace the DLP chip itself, but they are spendy. If it's under warranty, take it in and have it replaced.
