Still waiting to hear back from Consumer Electronics, the technicians that are working on the TV. They're supposed to call me today and let me know what they've learned about fixing the problem by calling LG techs. Once I hear, I'll share.
While waiting for them I did contact LG customer service about options I have in case the claim continues that they cannot fix the TV. They've let me know that I have the option to get a replacement TV or refund. Because this model has the issue pretty prevalently, I may just seek a refund and go back to shopping. I want it to be fixed, though, as I really like this TV aside from the banding issue.
