Thanks Jass. I will check out your settings, as I need to find something I like in the custom mode. I have only been watching in Cinema, as I have calibrated with DVE and gotten excellent PQ, with the only gripe being that I would like something between warm 1 and 2. Panasonic told me that for Fbr issues, they recommend Cinema or Custom settings. I am hoping to get a good picture out of custom and then maybe I won't get the brightness fluct.
If you don't see it, then consider yourself lucky and don't go looking for it. It really isn't the end of the world, it is just a pretty big fly in the soup if you ask me. I don't have any other issues with mine, so i am very happy for what I paid.
Two small kids and better motion capability is what drove me to plasma after my LED was broken. Glass is much easier to clean pb and J off of, lol.
However, I don't think you need to steer clear of panasonic when you upgrade, you just need to buy one of their high end models. When it comes to Plasma, Panasonic appears to have written the book.
