Summary: I got this one from Costco in 5/11. Now I run into terrible "popping" noise whenever it is turned on. It won't even stop after half hour later when it is turned off. I heard there are few problems with 2011 Panasonic models such as Fluctuating Bright Light etc... I have older Panasonic models (2008 and 2010) and they run great.
Summary: Let me first say that I am not sure if the unit was damaged during shipment. There were no signs of damage to the box or contents I could see. After powering the TV for the first time, I was presented with the setup menu and immediately noticed the flickering of the picture. My family did NOT see the flickering at first. After setting up the TV, I connected a DirecTV receiver and took a look at some HD channels.
Summary: I bought this tv primarily for 3D gaming. It was a cheap way to try out the whole 3D fad. I tried everything from PS3 3D games, 3D movies and 3D PC games using Nvidia 3DTV Play software. I was completely unsatisfied with the results. Wearing the glasses makes the display way too dark. Pumping up the brightness and contrast did not help, and really just made the picture quality worse. Cross-talk, double images or ghosting was present everywhere.
