Summary: It was a bit of a disappointment compared to the 5 year old 50" Panasonic Plasma TV I just replaced. The reviews on the 65" were great but I found that the TV doesn't stand up to all the hype. The biggest issue is brightness. It has a dark drab look compared to the older plasma no matter how I adjust it. Maybe there is something wrong with it, who knows. Also, this TV was not compatible with my Panasonic Home entertainment system. What a pain this was.
Summary: After reading all the reviews i thought i made a good choice, but I guess i'm used to the my Samsung LED. The picture on the Panisonic doesn't seem as bright and I'm not sure what it is, but the picture just isn't as good for what i use it for day to day(Uverse HD channels). Also my biggest issue with this is that it doesn't support all the video formats that my Samsung does (doesn't have all the codecs to support different .avi types).
Summary: Short review because most have already said what needs to be said. I agree: Picture is great. Highly reflective screen surface. I have a Major annoyance: Bzzzzzzzzz. There is a pretty noticeable buzz when the image is bright (White background) or what I'm watching was not recorded in HD. I don't know if this is my unit or the model in general. Others don't seem to complain about it. I'm easily annoyed by little issues like this... so who knows?
Summary: When i first got my 65GT50 I watched a 3D movie and the image was flawless no crosstalk or ghosting. However, when I updated to the 1.150 Firmware my 3D Content lost depth and had a bunch of crosstalk even re-watching content i had watched before updating the firmware. I called panasonic to report this and hopefully have it repaired, but all i got was a 3 day delay.
