I thought I would post the OFFICIAL panasonic statements on burn in and break in periods. This is for the 2008 models: http://www2.panasonic.com/webapp/wcs...tGroupId=249734. What is the "break-in" period and what should I do during the break-in period to minimize any risk of image retention?
When your plasma TV is initially installed, the first 100 hours of use is known as the "break-in period." During this time, to minimize any risk of image retention, you should:
Make sure the plasma TV is in a viewing mode (aspect ratio) that completely fills the screen. The panel is shipped in this condition, in what is called the "Just" mode.
Turn down the Picture setting (in the Picture menu) to +0.
Briefly engage the 4:3 mode and confirm the side bars are set to "Mid", or "Bright". This can be adjusted in the Set Up menu.
Always return the display mode that fills the screen (such as Just, Zoom, Full, or H-FILL).
Try not to view channels with stationary backgrounds or logos for extended periods of time.
Avoid extended display of static images (video games, computer images, DVD title screens, etc.).5. I've heard that plasma TVs can "burn-in" over time. What is "burn-in" exactly, and is it really a concern?
"Burn-in," or image retention, is an uneven aging of the phosphors in a display device, can occur on any display that uses phosphors to generate an image, including tube TVs, projection TVs that use CRTs, and plasma TVs. Such uneven aging happens when bright, static images are left onscreen for an extended period of time, which can leave a visible "shadow" effect.
Improvements in panel service life to over 60,000 hours have minimized the risk of image retention. In addition, screen savers, pixel shifting, and brightness level adjustments can dramatically reduce any chance of image retention. Use common sense when it comes to your plasma TV; don't pause video games or watch TV stations with station logos onscreen for long periods of time, and use one of the many display calibration DVDs available today for properly setting brightness and contrast.
The rule of thumb: if you don't worry about your traditional tube TV, you don't have to worry about a Panasonic plasma TV.
