So just a follow-up to my situation with the banding, for future people who may come across this thread and my post.
I first chatted with Vizio and they opened up a case for me. I sent them pictures of the TV and later my order confirmation from Dell. They are going to be shipping be a brand new one from Cali, could take 8-13 business days.
Overall experience with their customer support has been great. I did no have to wait long either for their chat or phone support, everyone was knowledgeable. And the instant the one rep opened up my pictures she let me know that I will be receiving a new replacement. They didn't give me any hassle, so the process has been pretty smooth.
I would recommend Vizio just on their support experience alone, never mind the fact that they sell good TV's at a great price. I had horrible problems with Samsung TV support before. This is my first experience with Vizio and yes I'm bummed about the initial TV quality, but I'm hopeful they're good customer service and replacement will fix everything.
