Is it that the first hours of usage are really critical to burn-in and because they weren't warned about it by the big dumb box guys they weren't careful? Anyone have an objecteive source to confirm that burn-in is most critical in first viewing hours?[quote]
OK, I've answered my own question with a good Google:
From a Panasonic White Paper, when the set is first turned on...
"Make sure the display is in a viewing mode (aspect ratio) that completely
fills the screen (there are often three or more settings from which to
choose). The panel is shipped in this condition, in what is called the
y Turn down the picture control (contrast) to 50% or less.
y Briefly engage the 4:3 mode to confirm the side bars are set to mid-gray
(there is usually an adjustment in the Set Up menu that takes the
sidebars from black to gray) to minimize the chance of burn-in.
y Return the set to a full screen (Just, Zoom, Full) position during the
first hundred hours of use.
y During the first hundred hours of use it is best not to view the same
channel for extended periods. This should prevent channel logos and
other fixed images found on some channels from being retained.
y Avoid any static images (video games, computer images, DVD title
screens, etc.) during the hundred-hour break-in.
After the hundred-hour break-in period, during the next nine-hundred hours:
y Continue to retain the picture setting at 50% or less.
y Limit the use of 4:3 aspect ratio mode (traditional picture size that does
not fill the entire screen) to 15% of viewing time.
y Limit the use of static images (computer, video games, etc.) to less than
10% of viewing time.
After one-thousand viewing hours, panels are much less likely to experience
The absolute best part is to limit watching any 4:3 material to 15% of the time until 1000 hours
. Unbelievable. I don't know how most people use these sets, but most of my clients are way too busy to watch lots of HD primetime live. They watch 4:3 stuff off their DVR. And they don't even reach 1,000 hours for a year plus.
Guess I wasn't missing anything. But it sure makes burn-in a MUCH greater problem than most on this thread make it out to be, IMHO. I will continue to recommend LCDs for most clients.
