I'm sorry to read about your issue with that new panel. It's a good thing that BB is taking care of it. How did you noticed that dead pixel? I do wonder how many people have displays that don't notice that defect?
Thanks, Robert. Finding a problem with something this new, big, and expensive was indeed a bit stressful. I noticed it when I was installing a Bluetooth transmitter for my AVR behind the TV and had the LG Home menu up. There was an app icon in the lower right corner of the display - white background with a red logo - and I noticed the dead pixel in the white portion. At first, I thought it was just a bit of dust on the glass but soon discovered otherwise when I tried to wipe it off with a microfiber cloth. I threw up a solid white frame on the panel and inspected the rest of it carefully. It's just the one dead pixel, but as Josh and others mentioned this is a $5K TV, and who knows if that one issue will get worse or not. Easier for me to get a replacement now while I still can rather than leave it and possibly have to deal with LG later, and their warranty may not even cover a single-pixel defect.
I also wonder how many TVs these days have dead pixels that go unnoticed. A stuck pixel is easy to spot because it's always on, but I think dead ones are a bit tougher unless you're actively looking for them or you just happen to notice, as I did.
