We purchased a Panasonic TC-P55VT30 in early January 2012. We used a series of slides we found out about on this (AVS) forum to break it in for the first 100 hours. We used the pixel orbiter and every other anti-image retention tool available on the set. Despite all of these precautions, our set developed burn-in (and it's burn-in NOT IR) in the upper left-hand corner, the lower left-hand corner, and the lower right-hand corner from MW3's HUD within 6-weeks' time. We played several hours per day (after work and on weekends) but NEVER left the game on pause. We also watched some full-screen programming (NetFlix) between gaming sessions. MW3's HUD still burnt the screen. All this talk about new plasmas being impervious to burn-in is absolute nonsense. Videogames with static HUDs will burn even the best plasma tvs (ours is top-of-the-line). And don't even suggest that we abused the set... We used the darn thing, we didn't abuse it. Throwing a controller at it would have constituted abuse. Playing games and watching movies constitute use not abuse. If you do get a plasma for gaming (and I do NOT recommend it), break it in for at least 200 hours using slides or other material created for breaking in plasmas. Turn the contrast down to considerably less than the default in game mode. Limit your gaming to no more than about an hour at a time and then run some full-screen programming (e.g., a movie, tv without static logo) for at least an hour or so between gaming sessions. Use a pure white screen (such as a screen washer) in torch mode (Vivid) once every couple of days to check for darkened areas on the screen. We're going to buy a second tv (a LED/LCD with 16 ms input lag, comparable to the Panasonic) for gaming and will not be using the plasma for gaming any longer. Bottom line is, plasmas... even the newest top-of-the-line plasmas... can and do burn in even if you don't "abuse" them.
