I've been noticing a fair bit of IR since my D6900 had a new panel fitted. It's not a major concern as it literally only sticks around for a few minutes. However I seem to have developed a bit of paranoia about it and if I watch a film with black bars, for example, I end up running the scrolling bars for an hour once I've gone to bed. I reckon on total I run my scrolling bars for around 5 hours a week. Does this seem excessive? I've heard some people say that using the scrolling bars too much prematurely ages your set. Is that true? Also is it a major problem to turn off your set whilst its showing some IR? Or is it best to try and shift it before switching it off?
