I stripped the smarts out of my old TV, and it finally got good again

I’ve had an old LG 47-inch smart TV that’s been sitting around collecting dust for years. It has a perfectly usable 1080p panel, but the smarts behind it have been obsolete for years. The last firmware update it received was in 2016, and its only accomplishment was to remove the Skype app. All modern streaming support has long disappeared, but I can’t justify throwing away an otherwise functional television.
