How To Fix a Cloudy LED TV Screen by Changing Your Settings

Clouding is a common problem for LED screens—especially when they use fluorescent backlighting. Clouding refers to uneven backlight which is caused by light bleeding into the visible part of a screen. This gives the television screen the appearance of having a white shadow or "cloud" when viewing dark scenes in a dark environment. This issue is especially common in new TVs and will likely gradually decrease on its own after a few weeks or months of use. If your screen’s appearance doesn’t improve on its own, follow these tips on how to fix a cloudy LED TV screen.

Change your TV settings

Typically, you can greatly decrease clouding on your TV screen simply by changing the television’s settings. Reducing the backlight level, turning on the light sensor setting, and changing the power saving setting can all help reduce clouding on your TV screen. Prior to adjusting these settings, turn off any "iris" or "smart sensor" features on your television. These features automatically adjust brightness based on how much light is in a room, and it will hinder your ability to make adjustments that properly diminish the clouding effect. To turn off this feature, go into your system settings and switch the iris/light sensor/smart sensor off.

• The first setting to change is the backlight level. You will find this option in the Picture Settings Menu. Once you find the option to adjust backlight, decrease it to the lowest comfortable amount. While it may take a while to get used to the lowered brightness, doing so should greatly decrease the cloudiness.
• Another setting you can adjust to decrease cloudiness is the light sensor setting. You should find this in the Setup Menu area. Once you have located it, turn the setting "on".
• Decreasing the contrast and sharpness settings to a minimum level may also help reduce clouding. These settings can be found in the Picture Settings Menu.
• Lastly, you can change the Power Saving setting. You’ll also find this in the Setup Menu. Once located, change it to low or high.

Solving the clouding issue on your LED TV screen may take some trial and error. We suggest you play around with these features by first turning them all to a minimal setting. Then, individually increase each setting to see if you can pinpoint the cause of your screen’s issue.

If changing your TVs settings doesn’t solve your backlight issue, there may be a problem with your backlight inverter board. This inverter works like a battery for the LED monitor and plays an important role in image visibility. If it fails, you can simply replace your TV backlight inverter board with a new one from Electro Parts. Doing so is much cheaper than buying an entirely new television, and with our wide range of options, you’re sure to find one that fits your model.
