I haven't seen a dead pixel since the plasma days. That said, I have seen a line of jacked pixels, top to bottom on a couple Samsung TVs in years past. Once, out of the box at install. Another, a few days after an install.

Just a question, how did you transport the TV in question? Was it standing up in a van? Or laying down in a truck bed? (the ones I had issues with had been laying down in my truck, way back in the day, pre-van. I always thought that could have done it.)
