Most TV's today are actually giant Android computers. I opened a friends TV a few years back to try and examine a back light issue and to my surprise there were just 3 small PCB's in the TV: Power supply, LCD driver/interface, and the video input board that contains an Arm SoC. The PSU had a small harness that ran to the other two boards and the SoC board had a ribbon cable to the LCD panel.
The Arm SoC is the real interesting part here as it also has WiFi and Blue Tooth interface, Ethernet, and USB port(s). They're like a giant black box Raspberry Pi. If we could get our hands on the SoC datasheet then its possible we could flash that SoC to run whatever OS we want and actually have a Smart TV instead of a spyware and malware vector. Though I am sure no TV maker would ever let the plebs disable their money making spying and data exfiltration schemes.
