Given a recent post in the GT50 thread I feel compelled to write this post. I am asking those who are considering running in their TVs unattended to think carefully about the risks involved. If you leave the TV showing a broadcast channel, you cannot be sure what will be shown. You really don't want to wake up one morning and discover that "We apologise for the interruption to this transmission ..." has been on the screen for an unknown number of hours. Equally, using run-in slides is not risk free either: "Of course, I woke up this morning to find the screen lit up bright green and the dvd player frozen."

From: http://m.cnet.com/news/samsung-plasma-wins-cnets-accidental-burn-in-test/57449881?ds=1 "Last night I left a dark grey break in slide on for 7hrs in error. Basically I forgot to enable slideshow. Nothing else was on screen but I now have large patches and poor uniformity on light grey screens I didn't have before." From: http://www.avforums.com/forums/18554192-post97.html There may be little to be gained from using a run-in procedure. There has been no thorough investigation of the effects of the various run-in methods. Any supposed advantages are based on little more than guesswork. Please, ask yourself if it is worth the risk. Thank you.
