OLED 65B7 - USB Power Stays On in LG webOS Smart TV Questions Posted February 11, 2018 I've had this issue too on my OLED55B7A. I'm not sure why it does it, but I assume it's due to the USB port being powered. It doesn't bother me as I can turn off the lighting, or wait until it turns off by itself. LED's draw so little power.
