How in the world do you know this "wave" is in fact burn-in?
I have over 300 LCD's on my network that run 24/7 and half of them have been doing so for 5 yrs and ZERO burn-in and I own four LCD TV's and dual 19" monitors and zero. I've never seen burn-in replicated on an LCD Monitor or TV and my network includes 400 PC's which I buy and manage them and no such effect. What you describe sounds more like banding not burn-in, perhaps overheating has replicated the wave on the panel as I fail to see how backlighting could burn-in it's light onto glass substrate.
True burn-in is close to impossible if you study the layers involved in an LCD unless of course you place a static image and leave it there for inifinity perhaps it may somehow replicate it. Owners Manuals will address it as a Caveat but it's the lawyers that place those paragraphs within not the engineers. Burn-in postings on LCD TV's are simply RARE as I've been here almost daily for 3 yrs and it's rare indeed.
