Non of the actual professionals or reviewers do know how it works. It’s only LG and their engineers. Some are saying it depends on how long the static images are displays but that’s outdated information. It’s more variable than that. If you want to read something more about it I would say visit AVForums. There is a topic about this with more detailed information.
I never said different sub-pixels didn't age at different rates, just that it is cumulative aging.
I don't find it mysterious, just that different colored pixels will age at different rates, and all of them will get dimmer over their lifespan. This does not seem that complicated to understand.
My personal opinion is that different panels will age faster than others (some seem to age exceptionally fast), and also it seems that some TVs are faulty and don't run their compensation cycle. I would look into replacement early if I saw either of those problems.

Long periods of static content will cause burn-in on OLED TVs. The red sub-pixel appears to degrade the fastest, followed by green and then blue. The effect appears to be cumulative, as even cycled logos do burn-in (but over a longer period of time).

Note that we expect burn-in to depend on a few factors:
- The total duration of static content. LG has told us that they expect it to be cumulative, so static content which is present for 30 minutes twice a day is equivalent to one hour of static content once per day.
- The brightness of the static content. Our maximum brightness CNN TV has more severe burn-in than our 200 nits brightness CNN TV.
- The colors of the static areas. We found that in our 20/7 Burn-in Test the red sub-pixel is the fastest to degrade, followed by blue and then green.

Hi all, I'm having some internet connectivity issues with one of my B7A panels. When I try to run Netflix, Hulu, Prime, YouTube, etc. the app fails to load streaming content properly from the net. The panel is connected via ethernet to a router and then to a Comcast modem. I re-set the router and modem: didn't help. This B7A has the latest firmware (05.80.15) and all the apps tested are using their most recent version. I have an identical B7A panel upstairs, NOT running the most recent firmware and it works fine.
Netflix: app loads fine and all preview images load, but when choosing something to watch it fails and goes to the try again/details screen. In Details it shows that all internet connections are fine.
Prime: app totally fails to load, completely black screen.
Hulu: app loads fine and preview images load, but nothing will stream.
YouTube: app loads fine, I can search fine, but when choosing something to stream it fails and goes back to the YouTube default screen.
Panel is connected to a power conditioner and surge suppressor.
I unplugged the panel and will test again when I get home today. Any thoughts? If it still doesn't work I'll reset to factory and see if it behaves then. Anyone run into this problem?
Assuming you are on wifi, try removing the wifi connection from the TV, then reconnecting and entering the wifi password again. These TVs definitely have a wifi bug where they will sometimes get "stuck" and the only way I know to get the connection working properly again is to do this. I have mine connected via ethernet to get around the problem, as it was happening for me maybe every 1/1/2 weeks.
