This is usually caused by an issue with the backlight of your television. When the backlight goes out or weakens, your TV’s brightness will fade in and out. If your television has an LED or LCD screen, it’s likely that the backlight is causing the fading.

Possible causes of the backlight fading include: faulty LEDs or CCFLs, a defective power supply, poor wiring, or physical damage to the display.
If you think the backlight might be causing your TV’S brightness to fade in and out, the best thing to do is to have it checked out by a professional. It’s possible that the backlight can be fixed or replaced in order to improve your television’s performance.
How do I stop my LG TV from dimming?
If you are noticing that your LG TV is automatically dimming, chances are you have a setting enabled called Energy Saving Mode. This feature can be changed in the Settings menu.
To change this setting, you must access your TV’s menu and select “Settings. ” Within Settings, you will see “General” and “Energy Saving” options. Select “Energy Saving” and then switch the mode from “On” to “Off. ”.
Alternatively, you can also manually adjust the brightness of the TV with the remote or by using the TV’s buttons. To do this, access the “Picture” menu and select “Brightness. ” This will give you an adjustable slider that you can use to increase or decrease the brightness according to your preference.
Be aware that although this may stop your TV from dimming on its own, it will also increase the energy your LG tv uses, so you may want to find a comfortable balance between brightness and energy efficiency.
As well, if you are still having issues with the dimming of your LG tv, you may need to have a technician examine it to determine what else could be causing the issue.
Why does my TV screen go light and dark?
Your TV screen going light and dark could be caused by a few different things. One possible culprit could be your TV settings. Check the backlight setting on your TV and make sure it’s not set too high.
Additionally, ensure that the contrast, brightness, and sharpness settings are all properly adjusted.
Another issue could be the power supply of your TV. If your power supply is damaged or has become disconnected, this could cause the screen to flicker or become lighter in parts. If this is the case, you will likely need to replace it.

Why does my LG TV get darker and lighter?
Your LG TV may be getting darker and lighter due to a few different causes. First, your TV may be using Automatic Brightness Control (ABC). This feature adjusts the brightness of the TV based on the amount of ambient light in the room, in order to optimize the picture quality.
Second, your TV may be using an Energy Saving Mode, or Eco Mode. This feature dims the backlight to save power and conserve energy. Third, your TV may be responding to changes in the signal coming from the source device.

Lastly, some LG TVs have a TruMotion setting, which will adjust your picture settings based on the refresh rate of the content you are viewing.
If you experience frequent changes in brightness, you may need to go into your Settings and make adjustments to the features mentioned above to find the most comfortable viewing level.

In addition to the ambient light detection setting, there may be a bug in the TV’s software or a setting you didn’t know existed that is causing this issue. If this is the case, you will likely need to contact the TV’s manufacturer and discuss the issue with them.
