If I could turn a Samsung Smart TV into a dumb TV, or even just a basic monitor with input selection and basic volume control, I'd definitely take it.
Pretty much the same with my newly acquired LG Smart TV. I thought I might like webOS, since it's technically a descendent of palmOS, but oh no. No no no.
I've opted just to not plug it in to the network and not provide a WiFi password.
Yup. Sony bravia smart TV has died recently. Can't run the OS without crashing on the home page. So much input lag feels like running ancient hardware in early 2000s. Crashes navigating picture settings and helpfully resets them back to default for you, so you can't really functionally change picture settings.
How I wish I could just strip this thing down into a monitor with a set of speakers... Screen itself is perfect condition of course but the OS turned it into ewaste.
