a day after the return period has expired my LG B9 OLED TV has started to have problem. It can only power on (using remote or the built in power button) for a second or 2 but shows vertical lines before it turns itself off. Has anyone had this problem? LG technician is coming to replace the panel (after 1 week of waiting for the part), but I'm not sure if it's the panel or the board/power supply. I cant believe this high-priced TV can go bad after slight use
