Why is my TV Screen White?

A white TV screen can occur on any TV and is a common problem. The TV display can go white because the TV is in screen-saver mode, or because of clouding found in the power saving settings. 

 

Daydream mode or Screen-saver mode

One reason why your TV display is black or white can be because it has entered the daydream or screen-saver mode. The daydream mode or the screen-saver mode is on by default in the settings. The daydream mode becomes active when your TV’s clock is not the same as the internet.

When the clocks don’t match, the TV fails to download images and instead displays a white screen.

This can be resolved by going to your TV settings and correcting the date and time. 

 

Clouding

Another reason why your TV display can look white can be because of clouding. Clouding can also be resolved easily by changing the TV settings.

  • Go to the TV settings and then to display the manager.
  • Reduce backlight.
  • Turn on the light sensor setting.
  • Change the power saving settings to see if that removes the clouding.

 

What do you do when your TV screen turns white?

Since there can be two reasons why your TV screen has turned white, there are multiple ways you can try to resolve it.

The first thing you have to do is to check the TV clock’s time. If the time is wrong, this is how you match the internet time to your clock’s time.

 

Follow these steps:

  • Press Home on your remote.
  • Go to ‘Settings’ and select it.
  • Under Device Preferences, go to date and time.
  • Unselect the ‘Automatic date and time’ option.
  • Set the date and time manually.

 

What causes white horizontal lines on the TV?

White horizontal lines appearing on the screen are caused by failure of the gate drivers. Gate drivers are one of the parts of the panel that are difficult to replace. This can also occur due to technical errors or glitches in the TV’s functioning. 

First, check if the lines appear on every input. Try switching to different channels or apps, and see if the lines are visible everywhere. If the lines show up on every input, run a picture test.

  • Press the Home button on your remote and go to settings.
  • Open the picture menu.
  • Select the ‘Picture test’ option.

If lines are appearing during the picture test too, then your TV most likely requires a repair. But before that, you can try these steps to see if it helps:

  • Open the settings menu and go to General Settings.
  • Find the Reset to initial settings option and click on it.
  • Restart your TV.

 

What does it mean when your TV has white spots?

When a TV shows white spots, it means the TV has dead pixels or the light is failing to spread all over the LED reflectors.

  • Dead Pixels: The LED TV screen is made of many pixels. Each pixel emits light to create a whole picture together on the screen. When these pixels are stuck in just one certain state or are damaged, they appear as the white dots or spots on the screen.

If the reason behind the white spots on your TV is dead pixels, then the only way to reach a solution is to get the screen replaced. Make sure to get your screen replaced at a reliable location to avoid such errors.

  • LED Reflectors: Every LED installed in the TV is connected to a reflector. The reflector ensures that the light spreads evenly on the screen. When any reflector shows any problem, it fails to spread the light and leaves a blind spot. The white spots that we see on the TV screen is that blind spot.

This does not require a replacement, but a service provider can easily repair it.

Daydream mode or screen saver mode can also result in a white screen. This setting is, by default, turned on. The daydream mode is triggered when the time and date are incorrect on the TV.

The date and time of the TV are usually associated with the internet. So if the dates don’t match, the daydream mode turns on.

 

You can eliminate the white screen on your TV by correcting the date and time:

  1. Go to the Settings of your Tv by pressing the Home button on the remote
  2. Go to Device Preferences
  3. Select the Date and Time option
  4. Set the correct date and time manually

After you have corrected the time, follow these steps:

  • Press the Home button on your remote.
  • Go to Settings.
  • Go to Device Preferences and click on the Screen Saver, then Turn screen off (this is for Android TM 9).
  • Go to Screen Saver and set it to Sleep (this is for Android 7.0 and Android 8.0).
  • Select the option Daydream and set it to Sleep or to None (this is for Android 6.0 and earlier).

Bad reflector can create white spots on your TV screen. The TV screen is made of LED light. Every individual light is connected to one of these reflectors. The reflector spreads the light uniformly on the TV screen that creates the complete image.

Sometimes, a problematic reflector fails to spread the light entirely and leaves behind blind spots. This is seen as the white dots on the TV screen, resulting from incomplete image formation.

The Tv screen is also made of pixels. Every pixel has its own light. These lights change and keep moving along with the motion of the images on the screen.

When some of the pixels fail at performing, they get stuck in one position or a state. In this position, the pixels look like a white spot on the TV screen. Dead pixels that no longer can display different colors cause white spots. The solution to this problem is screen replacement.

Pixels cannot be repaired individually; hence your TV will require a new screen. A good quality screen ensures that such problems don’t occur. It is always advised to get a new screen from a reliable place.
