LCDs don't burn in. Ghosting/image retention on LCDs is temporary, unlike burn-in, which is permanent.
Your advice isn't great either. Turning down the brightness on an LCD will do nothing to save the panel, as the brightness is the brightness of the backlight, and the image retention ("sticking") is on the panel. The panel would suffer from sticking even if the backlight were completely off.
Also, the idea that burn-in is most critical in the early stages of a plasma's lifetime is just false. Burn-in happens on plasma because as the pixel is used, it gets dimmer (this is why plasmas get dimmer over time). Now, this is a decay cycle, like radioactive half-lives. If the panel is new, and a pixel gets "burnt", the pixel may be (let's say) half as bright as the rest of the panel. But if the panel is older, the whole panel will be half brightness and the burnt pixel will be 1/4 brightness. In that way, the burn in later is of lower magnitude.
But in the end, your eyes see light exponentially anyway. If a pixel is half as bright as the rest, it looks just as bad, even if the rest is down to 1/8th brightness and the burnt one is 1/16th.
The only way to prevent burn-in on a plasma is to be careful about what you display. If you get burn-in, the only way to remove it is to burn the non-burnt pixels a bit more to come down to the brightness of the burnt ones (burn with an inverted image). It sounds drastic, but given how minor burn-in usually is on plasma, it's not a big deal.
If your LCD gets image sticking, just play some constantly moving images for a while. Play a long movie on loop. The statement above that you need to run the unstick material for about twice the time as you ran the material that made it stick is a good guideline, modify as appropriate.
In general, a good LCD will not stick noticeably unless you show the exact same image for 30 mins or more. In more normal use you don't need to sweat it.

Really? Your statement is just the opposite of what Panasonic says!
Panasonic's website gives an introduction to plasma use and "break in" of the early stages of your new plasma. They specifically give certain settings not only for the first 100 hours [use lower contrast, keep all content to full screen [1:78:1 with or without gray bar modification], avoid static images, etc, but for the next 900 hours also (similar settings but contrast can be increased some).
Also, you should never use the "dynamic" or "vivid" picture setting on a plasma, unless you have the brightness and contrast at very low settings.
As for anti burn-in protection, I recently learned that all 2007 Panasonic plasmas have the built-in feature with the pixels moving ever so slightly, and never fully stationary.
One guy's recommendation for the first 100 hours, is to play the PLANET EARTH HD-DVD or Blu-ray disc [1:78:1 native ratio] in a loop for about 8 to 10 hours a day, for around 10 days. Then your new plasma is broke-in, and you can increase the brightness or contrast to a mid-setting for the next 900 hours.
