I mentioned in another post here that I opened a friends TV and found just 3 PCB's: Power, LCD interface, and Video SoC. The video SoC is an Arm SoC for TVs that runs Android complete with video input switching matrix and processing. The SoC board had Wifi, bluetooth, Ethernet and USB. It's all there.

My dream is to hack that SoC to boot whatever OS. Though good luck getting the datasheets...
