I don't know how severe it is, but I can definitely see it while I'm running my break-in dvd....
sigh... that's all... I can only hope for the best...
Your LG should have 3 IR prevention modes. Well, actually, one IR prevention mode and two IR removal modes.
Go to Picture -> Options -> Image Sticking Minimization
I have mine set for Orbit normally. It moves things around in an...Orbit...when the set detects a static image for too long.
There is also a reverse mode which kind of looks like a film negative and...
White wash. It is this latter mode that will probably fix your issue. As the name implies, it turns the entire screen bright white and washes away retained images. Try it for three minutes and see if that helps. If not, rinse and repeat.
I talked with an LG tech rep about this issue and he really had no reason to give me bum scoop as he wasn't on commission. Anyway, he indicated that it would be darn near impossible to get true burn-in on any 2007+ model LG.
There were a lot of technical reasons including pixel shifting ect, but the most basic one had to do with phosphor life. This current crop of sets has about 100k hours to 1/2 brightness. Which means that assuming you stuck a blazing red logo in the middle of a black background for 10 hours straight, you would burn through far less than 1/10,000th of that area's phosphor.
His point was that, worst case, 9-12 hours of normal viewing should clear up the IR you are seeing. Or 2-8 minutes of using the white wash mode. He suggested 2 minutes, check, 3 minutes, check, and then a final 3 minutes.
Please let us know how it turns out.
