Summary: Since new this TV has had problems maintaining a stable WiFi connection with my network. Obtaining software upgrades is difficult. Using Netflix or any other web application is hopeless. Tested many options. All other laptops, TV, and DVD players in home work fine with my current WiFi network. My final solution involved attaching a Samsung Blu-ray player to the Panasonic LCD TC-L47ET5 TV and using it to view Netflix and other web applications.
Summary: I've had this TV for 9 months since late 2012. So far there is no major issues and I like it for the reasons that other reviews have covered, so no need to repeat. Here are something that are not so great and I think can be easily fixed by a firmware or minor hardware update. Then this TV would be a great set.
Summary: Picture is nice. Sound is a lacking. I will end up buying a sound bar to go along with this. We use Netflix 80% of the time and one thing that is VERY annoying is black flashing while watching any content. It may occur a few times a minute or once every 30 minutes. It varies. From research I've done this happens when the video streaming mode changes.
Summary: I picked this TV to replace an older Samsung LCD; my primary uses are games, sports, and the occasional movie. I used it for 2 weeks steadily. This TV was easy to set up - it found my Wi-Fi network quickly and offered a firmware update which installed without hassle. The remote is easy to use and the menus are responsive. The settings are, unfortunately, few, as it seems to lack advanced picture controls (white balance and the like).
