Your info on plasma's is very outdated Judas. Burn is nearly impossible on modern plasmas, I've read many reports of people who had demo plasma's running news channels 24/7 for months and all it took was running the wipe feature on the panel to remove the logos. Image retention is still a factor for Plasma's; I have one of the worst offenders for IR (2009 Samsung) and after 500+ hours it's hardly noticeable and removable in seconds. I've never heard of image quality being reduced after 2500-5000 hours and the HDTV crowd are some of the most scrutinizing consumers around. These guys will calibrate their friggen' tv if they move a lamp There has been massive backlash from Panasonic models that had black levels lighten over time if was you described happened then Plasma's wouldn't be purchased at all. I'm gonna have to call BS.
