Yeah, inside the enclosure of a modern TV is an LCD panel connected to a board the size of a raspberry pi that holds a SOC and some input connectors. There just

  Hmm, my family once replaced our LG 1080p TV's mainboard after the HDMI ports failed, then the TV stopped powering on past the splash screen at all. The built-in content apps (the early days of smart TVs before they turned into a surveillance capitalism hellscape) are dead, and 1080p non-HDR is obsolete for pixel-peepers, but for our limited use, the screen still works just fine.

  It kind of depends on the failure modes. There was a wave of Samsung TVs which were a big victim of bad capacitors at the time. Replacing <$1 worth of caps would often salvage the TV. Also, a number of TVs these days fail because of poor phosphor coatings on the light strips causing color issues and uneven brightness. The stuff literally starts falling apart inside the TV. A quick clean and replacement light arrays ( often <$75) will then refresh the TV, making it like new again for at least several more years. Hopefully the replacement light arrays will last longer. Sometimes the power supply, core logic, and inputs will be on separate boards. This means if an input connector gets physically broken it may be possible to replace just the board for the inputs instead of having to replace the entire board. Even then, assuming you can find it the board itself can be significantly cheaper than the entire TV. YMMV on parts availability though.
