In this article I will talk about the operating system of televisions and whether it is possible to update the operating system of the television to a new version. I don’t mean just to put a new patch (e.g. 2354 instead of 2351), but for example to update the Tizen OS in a Samsung TV from version 5 to version 6.
The short answer is that this is not possible, the TVs do not have a transition to a new version of the operating system.
Why you can’t update Tizen OS on your Samsung TV to a new version
The reason for this is that the TV uses a special way to write commands compared to the computer.
If the computer has only basic commands written to the permanent memory (BIOS) (these commands allow the device to operate with minimal parameters, such as the minimum screen resolution). When installing the operating system the installed components are automatically detected and configured. The screen resolution is set, the memory is checked and so on, after installing the OS the computer is ready to work.
On the contrary, many more parameters are recorded in TVs: screen matrix type (screen model), supported screen frequency, region, and many other parameters.
These settings affect the operation of the TV, and if you select them incorrectly, the TV may not work. The TV doesn’t automatically detect component settings.
As a result, one model of TV can have several modifications with different parameters (depending on the region and configuration).
The manufacturer must take into account all these nuances, because if you make a mistake, you can break the TV, to repair it you will need to rewrite the right parameters into the chips, and this can be done only in the service center.
Such a situation happened wing Samsung customers in 2020. When the player was turned on, it accessed Samsung’s servers and downloaded an incorrectly configured file. Thousands of Blu-ray players and home theater owners were unable to use their devices.
To fix the problem, they had to send their devices to service centers for reflashing the BIOS.
How the process of updating the OS on your Smart TV works
The TVs don’t have a global operating system update, the update doesn’t affect the settings. Only the user interaction shell update is downloaded. The app store or user preset settings can be updated.
You should know that as a rule, manufacturers support their TVs for 3-5 years. After that, the TV is considered obsolete, updates are no longer released. After 7-10 years the TV is considered old, you probably can’t have it repaired at an authorized service center.
