First time poster here, though I've lurked on the site a few times. I recently noticed burn in on my B6 that was purchased in Oct. 2016 (seems to be a common date mentioned) and thought I'd share. I'm sure others have brought it up, but my burn in is from the freaking bright red NETFLIX logo on LG's app! No burn in of any kind from any static network logos or news channels, yet burn in from a NETFLIX logo caused by casual browsing for no more than 10 to 15 minutes at a time.
I own two Pioneer plasmas, each purchased years before the OLED, and have NO burn-in, so I figured I'd be safe with the OLED considering my viewing habits never caused any problems on a plasma. Yet, just normal use of LG's NETFLIX app caused burn in. WHY would LG design an app that they know will damage their TV? And if they didn't know when they designed it, they do now, so why haven't they updated the app and addressed the problem? Update the app and remove the logo! I don't need to see a constant NETFLIX logo in the corner of the screen, like I'm somehow not aware that I'm browsing NETFLIX and I need to be reminded.
Anyway, LG seems to be aware they have an issue on their hands, and about 5 days after submitting my complaint (with pictures, proof of purchase...etc) I was contacted by LG and they agreed to replace the panel free of charge. If they would have done anything less, this would have been the first and last LG product that I purchased.
So, though I'm a bit frustrated that I've "babied" the OLED more than any plasma I've owned and STILL got burn in from LG's own freaking app, I am satisfied with LG's response to the problem and impressed that they seem to be willing to accept responsibility for their product. Hopefully the new panel is less prone to burn in.
