Theoretically, the best you can do is use some method to try to apply the same degree wear to the less worn phosphors, but that doesn't actually mean *real* recovery -- it just means you'll end up w/ more even wear, which will still ultimately impact the overall PQ, no?

I believe you are correct. My only experience with the screen washes was when a friend burned an image into his plasma. After leaving the screen wash on for about 3 hours we put up the all white screen to check for any retained images. There was no visible retension afterward. So, the technology does work. At least on his Panasonic plasma. I own a Samsung plasma. I've had it for 14 months with no problems at all. I watch widescreen movies all the time and have yet to see any image retension. This whole burn-in thing is really nothing new. The same thing happened with old CRT displays. People didn't notice it as much because they were watching smaller screens at around 19" to 32" that had limited resolution. Now, we have 40" and up with high resolution and the image retension is more noticable, but, not new.
