If I have to go get the model number I will. But maybe it happens on many models? What is this green filled small battery icon trying to tell me? It's never appeared before until lately. I'd say the TV is more 8 or 9 years. But it's a flatscreen with many ports. A Chromecast is plugged into the HDMI but the power to it has been unplugged for several years? I'm clueless! Anyone else have this?
