There are no pixels on a DLP tvs. If you stand too close to any tv you will see "things". Unless they show up in normal viewing on all inputs they are probably nothing. However, if they bother you and show on all things, TV shows, DVD, etc., there could be a problem and you can call for service or go to a store and see if you can see them on other similar TVs. Also, be sure you have adjusted your tv for best viewing. Check the Samsung HLS thread for settings.
