It looks like the Panasonic prevents burn in http://toplcdhdtv.com/panasonic-hdtv/panasonic-viera-tc-p50s30-review/ It is also good to take advantage of the image retention tools that the TC-P50S30 provides to prevent unwanted burn-in. The Pixel Orbiter is an essential feature that should be turned on so any static images that appear on the display for too long won’t burn in. You will often encounter these images when watching certain channels where the logo is constantly shown on the corner of the screen. You may also need to reset the pixels by activating the Scrolling Bar for a few minutes. This writes a gradient bar to the screen that should start from white to black. The Pillar Bar Brightener also changes the pillar bars to bright gray so image retention is prevented.
