If the TV goes dark by itself, could be due to several causes. Here are some steps you can take to try and fix the problem.

Check brightness settings

Your TV’s brightness setting may be incorrectly adjusted, which may cause the screen to darken. look for the option brightness setting in the TV’s menu and adjust the value to see if that solves the problem.

Smart TV eco mode

The process to follow depends on the make and model, but in general you will have to access the Options, Settings or Setup menu, choose Image and then select Advanced settings. Finally, choose Brightness and adjust it by moving the slider to the desired setting, scrolling left or right as desired to make it brighter.

Check power saving settings

If your TV has an energy saving option, make sure it’s not enabledas this may cause the screen to dim or automatically turn off after a period of time.

Your Smart TV’s energy saving features can help reduce energy consumption and reduce eyestrain when you watch TV in a dark room. Some TVs have a light sensor, so the picture will be brighter or darker depending on the lighting conditions in the room. I could turn off the automatic brightness control increase the brightness of the image.

Eye anti-stress mode?

We mentioned it in passing in the previous point, but he deserves yours. Some Smart TV models have brightness settings that are not fixed but depend on environmental conditions. There are eye strain prevention modes that reduce blue light and the overall feeling of being dark.

Sometimes, having the “EyeComfort mode” activated (called that by Samsung, LG or Philips, but it can vary in other brands) can be the cause of those screen dimmings for which we can’t find an explanation. EyeComfort mode is a display option in the customizable image which provides a comfortable picture setting for viewers’ eyes based on sunrise/sunset times and surrounding ambient light. The sunrise/sunset synchronization function in EyeComfort mode may work differently depending on the area and network connection.

To disable it, follow these steps

  1. Press the Home button on the remote and select Menu.
  2. Scroll to Image Mode and press the Select button to change the Image Mode.
  3. Changes the image mode from EyeComfort mode to Optimized.

firmware updates

If you have problems with your Smart TV, you should always check if there is software updates availableas they may contain a solution to your problem and that in a later update some of these bugs were fixed.

If your Smart TV is connected to the network it should automatically apply these updates, but it’s not always foolproof and sometimes you’ll have to do a manual process. Check the manufacturer’s website to see if an update is available and follow the instructions to download and install the firmware.

It could be a technical problem

At the hardware level, make sure the TV is properly connected to a stable and reliable power source. An unstable power supply can cause screen issues.

TV technician

If none of these solutions work, you may need to call a technician to check your TV. There could be a hardware problem or a faulty component causing the problem.
