After reading countless posts on the above mentioned subject and seeing how much of a concern it is to countless members I need to state my facts on what we have experienced.
I own the Samsung PN50A450. (BTW - I love this TV
I joined the AVS forum in fear of the horror stories I have read/heard (true or not
) from many people who have owned plasmas and in hopes that any information I came across on this forum would either put my mind at ease or find a way to reduce the chances of aquiring those famous words 'BURN IN'.
Well, it's been a month since we've had this TV and we tend to watch our content full screen. HD programming is awesome! From time to time we will have the occasional grey/black bars but they have proven themselves harmless in every way. I was so paranoid
from the start that I ventured into downloading the Break In DVD. I wanted to pass those crucial 100 or so hours that everyone was talking about. It turns out that I never had to use it. I was SOOOOO paranoid about burn in, yet I've never even used it once! I simply used my common sense along with many other suggestions from other AVS members. The Break In DVD is not needed at all.
We've only had a mild case of IR from the CNN news channel. It wasn't the CNN logo it was the 'LIVE' word displayed in white that caused the IR for a day or two but went away with normal TV viewing. I've only used the scrolling feature for that instance only and never used it again (about 15 minutes worth and realistically it was not even needed). I do have the pixel shifting feature on but that is all.
It's been almost a week since I've tweaked my settings to aquire a better picture and we have not noticed any type of IR at all since. CNN or any other stationary logos are no longer of a concern, if anything they may create some mild IR.Our conclusion on burn in
: In order for burn in to occur, you must really have to abuse the plasma. Example being: Plasma being on torch mode from day one and leaving a static image displayed for days on end.Our conclusion on IR
: Although we've only ever experienced IR once, it did go away quite easily. Based on countless other posts I have read, IR gets reduced considerably as the set surpasses it's break in period. If you do experience IR, mild or severe it can go away, period.
I should also point out that up until a week ago I kept my contrast and brightness at around 50, I've now upped my contrast to 75 and lowered my brightness to 47. IR has not appeared at all.
We are so happy with our plasma we would not hesitate to get another one if and when the time comes.
