I am the proud new owner of a Toshiba 51H83 HDTV. It has been working great and has a crisp, clean picture when used with my progressive scan DVD player. I have had it for about 2 weeks, and i bought a warranty with it from the Best Buy, the store i purchased it at. When i first got it, i didn't notice anything strange when the screen was all blue or all white. But just today, when i turned off my DVD player and the screen went all blue, i noticed several "pixels" not emitting any light. I looked across the top of the TV and i found about 4 of these pixels all black, some larger than others. These are very hard to notice, and they don't really bother me when watching, but i'm still curious as to where they come from and if i can use my warranty to replace the screen if too many of these pop up. And yes, i did make sure they were not things that were on the screen itself, and i take very good care of my T.V. One more thing, when playing DVDs, there is sometimes a fuschia colored line at the bottom of the TV that is only noticeable upclose.
