What are the functions of the Samsung TV service menu

As already mentioned, the average user is not recommended to experiment with the service menu on Smart TVs, including the Samsung K series or any other series, even J. The point is not that this is a whim of the developers. On the contrary, users can press the wrong key on the remote control, and all settings will fail, which will lead to a complete loss of the normal performance of expensive equipment.

But in the hands of the master who entered the service menu of TVs, it can turn a standard Smart TV into almost a home theater. Nevertheless, sometimes such settings can be opened completely by accident, by involuntarily pressing some key combination. If this happens, then you can change:

  • The spectrum of the image, for example, by choosing a green palette or red, in connection with which, the picture on the screen will become a country. Few people want to watch TV in this format.
  • Screen image size options. It may turn out that the picture will not occupy the entire screen, but only half of it, moreover, from below, from above or from the side. The picture can break into pixels, and tolerate other, unpleasant changes.
  • Naturally, the service menu of a Samsung TV can change the sound parameters, making it so that even at the highest volume, the device is barely audible. Or uses various sound effects, due to which an echo may appear, acoustics will increase, which also does not contribute to a comfortable viewing of content.
  • In addition, once in the service menu of a Samsung TV, you can connect and disconnect various built-in functions.

In general, if the user needs to change any automatic settings, then this is done right here.
