Just wondering what some of you might think the best way to remove image burn on Plasmas is? I have a plasma here that has some color icon burn in from a computer signal, and so far I've been using the all white method where I just leave a white screen up for as long as needed.
While that works, I am curious if there is a better way to do it? Last time I did the all white method it took a week of white screen to remove some ESPN burn in along the bottom of a Vizio. So I am curious if there is a faster/better method?

As an informational point, the mechanisms behind image retention (IR) vs burn-in on plasmas are completely different. Burn-in is the result of uneven aging of the phosphors, which results in some pixels producing less light than the surrounding pixels given a particular APL. Burn-in is permanent. Image retention is (IIRC) the result of MgO sputtering, which causes electrons to be deposited in adjacent cells, leading to a visible after-image. IR is completely reversible. Both result from static images being left on a plasma, but what actually causes them is almost completely different. Pioneer plasmas seem to have the most resistance to IR, followed by Panasonic, and the Samsung/LG having the least resistance.
To answer your question, you're just as likely to remove IR from normal, full-screen viewing of normal material (without static logos and such) as you are from a full-white screen or a "wipe" video. I haven't seen any data that indicates that there is any method that's capable of removing IR from a display faster than any other. Of course, if you're leaving a full white screen or wipe video going while you're not normally using your TV, it would disappear quicker than just through normal use. If your plasma has an orbiter function, I'd highly recommend turning that on, as that will help prevent IR from ocurring in the future, even with static logos.
