It is an annoyance for some users of our local community, that it has turn out to be pretty much extremely hard to buy a Tv set which is not a so-called “smart” Tv. These units contain a personal computer as nicely as the screen, and it boots into a locked-down OS with a person interface and a load of streaming apps. Can anything at all be accomplished with them other than what their companies intended? [Nina Kalinina] has managed it, getting the mainboard from a discarded Liquid crystal display Tv set and liberating the ARM Linux board inside of.
On the board are all the inputs you’d expect from a Tv set, together with Ethernet, and a few of additional USB ports concealed in the WiFi interface. There is a UART offered on the SCART connector, and accessing the U-boot menu is obtained by the abnormal usually means of sending a character to the infrared port working with a Palm Pilot. Shockingly the unit tree in the Flash was editable, so with the Linux OS accessed, the board was exposed as getting a twin-main Novatek SoC.
This is reminiscent of the times when the new hotness was dragging a Linux box out of a residence router, and just as people were promptly eclipsed by low-cost boards these as the Raspberry Pi, so may well these Tv set boards satisfy the identical fate. If, nonetheless, they can be created to generate a display screen with some thing extra helpful than the Tv set interface then that may modify, as who wouldn’t want to make an old wise Tv a bit additional beneficial?
