Summary: This is a great TV BUT.................. The screen is highly reflective! If there is any ambient light in the room, as soon as the picture gets at all dark (e.g. night scenes), you will be seeing reflections of the room! Unless of course you paint the room black and make everyone wear ninja suits. This may be true of all plasma screens but I've deeply regretted not getting an LCD TV this time!
Summary: So much research carried out before purchase to get it right! Now feel totally let down! Bought a Panasonic TX50ST30B 3D singing all dancing TV. Only to see a blurred display no matter what configuration we selected! But more importantly, on the Right Hand side of the screen was a constant flickering multi coloured "Side Bar" visible at the onset of Power On & Set up! Our 10 year old SONY Plasma is back on the stand, because it has a better quality picture!
Summary: I Have the Panasonic 50ST30 plasma and have noticed the screen has green blobs in a couple of places (faint, but defiantly there). I have read around on various forums trying to alter the settings to get rid of this, but from what I have seen this is a major fault with the 2011 Panasonic plasma models.
Summary: I bought this TV (from comet - not Amazon - useless customer service) and within two months the display failed leaving a black line down the left side of the plasma screen. This is made worse by the fact that I bought a 42" version for the bedroom and it did exactly the same thing. When Panasonic make a big deal about the quality of their displays then this is worse than disappointing - wish I had bought the Samsung.
Summary: I wanted to wait a few months before i gave my opinion on this set. I never suffered any issues with my set in regards fluctuating brightness or any green tinges BUT there is only one mode for watching on this TV, dynamic. I have an Xbox, mac Mini, and cable running to my set and all of the other modes are UNBEARABLY dark, I cant see how anyone would use the other settings.
