2017 LG B7 - FW Issue(?): Sometimes rear USB ports powered on indefinitely?
I'm going nuts trying to get anywhere with customer service. Figured I'd try posting here, didn't put it in the owner's thread to hopefully increase its visibility... This is pretty much a copy/paste of a question I asked on Reddit a month ago.
The USB ports (and therefore the USB powered bias lighting) on the back of the TV sometimes stay powered on after the is turned TV off. Usually, the USB ports turn off 5-10 minutes later. No big deal... But after updating the TV recently, sometimes the USB stays on indefinitely. I wake up in the middle of the night 5-6 hours later and notice the bias lighting is still on meaning the USB ports never powered off.
My theory: I asked this on reddit last month and was told that when the USB ports stay powered on after turning off the TV it's an indicator that the TV is doing an automatic pixel refresh. That every 4 hours of accumulated screen time, it does a pixel refresh for a few minutes. Additionally, after 100 hours of screen time it does a longer 1 hr pixel refresh. Now 6 nights out of the week, the bias lights turn off instantly or within 10 minutes, but approximately once a week this issue occurs where they stay on indefinitely. I'm thinking there is a bug with the 100hour/1hr pixel refresh and it doesn't end when it's supposed to. That would explain the seeming randomness of it.
This definitely just started occurring after I updated the firmware recently, but honestly I'm not sure what firmware I was on before this...I don't think my TV was connected to wifi for a while.
tl;dr: Updated my TV's firmware to 5.80.15 a couple months ago, since then -sometimes- my USB-powered bias lighting stays on indefinitely after turning off the TV (meaning the USB port is still powered on). This occurs approximately once a week...Normally it shuts off instantly or within a few minutes.
Is anyone else experiencing this?
P.S. While type this and banging my head against the wall with customer service I supposedly got through to a LG "OLED Specialist" (that none of the tech support people were initially willing to let me speak to directly) who said the would look into it and test it on their own TV they had in office as well as escalate it to the engineers. I have no idea if he was just trying to get me off the phone but seemed much more understanding than the general tech support I had previously spoken too. Seriously, I felt like that 14 year old kid who discovered the Apple FaceTime bug and his mother, trying 16 different ways to report the bug to Apple and no one would listen or take them seriously. Trying to get past CS reps to report bugs to people with actual technical knowledge is insane.
