Is there somewhere I can download a Pixar movie loop folks are talking about here that I can try that might help remove some stubborn IR? I wanted to try the whitewash mp4 mentioned by Zoyd, but for some reason my ST50 will not play a .mp4 file, says it's not readable. It will play a .mov though.
I initially had no indication of IR problems until now. Now I have some serious IR from playing Halo 4 since mid-December on my 60" ST50 and I'm worried it might be permanent. It's mainly the HUD shield bar indicator at the top of the screen. I thought I was being careful enough, playing maybe 2-3 hour sessions, which isn't unrealistic, then letting the TV run on normal content after gaming until it auto shuts off after 3 hours. But just last week, I noticed that the shield bar was not dissipating and I can see the ghost image on anything now, except an all blue screen. (The HUD bar is light blue with a white border).
I'd been playing maybe 5 days per week, for the past 4-5 weeks, so the IR has happened as a result of repeatedness apparently, not just one or two long sessions of something.
I've tried many of the things mentioned here the past week to try and cure it, nothing works. I've now been letting the TV run on normal HD content continuously to see if it might go away, but I'm not too hopeful. I bought the set in June, 2012, ran D-nice's slides for 100 hours exactly, and then put in his recommended ST50 2012 custom settings, and those are the settings I gamed on, I never use game mode. The TV had roughly 400 hours on it before I started Halo gaming.
Anyway, I'd like to try 72 hours of a pixar movie loop if I could find one. Bottome line though, is the 2012 ST50 does seem very prone to IR from gaming HUDs, which is a bummer because I really like the TV otherwise, and it's fantastic to game on. But alas, it's not mean to handle it for any lenght of time apparently.
