Samsung LED TV leak is not accidental
The phenomenon of light leakage from televisions is not an accidental event. This is a common phenomenon in the industry. The high-end TV leakage phenomenon is relatively slight, which is regulated in the industry. Due to the different grades of LCD screens, the degree of light leakage is also different. The "General Specification for Digital TV LCD Monitors" implemented on January 1, 2007 clearly stipulates that LCD TVs must have a ≤ 4cd/m2 standard for light leakage in a full black screen.
Although the LCD TV in the case of full black screen light leakage must be ≤ 4cd/m2, but the specific measurement standards and methods are in the hands of TV manufacturers, the user himself is not clear, if the manufacturer insisted that this is the TV's "Normal" phenomenon, this bitter fruit has to be swallowed by users, so Samsung TV leak phenomenon is a quality problem, this degree of grasp in the hands of TV manufacturers themselves.
Up to now, there have been a few examples of failures in Samsung's television leak protection. Let's review a few typical cases.
Samsung TV's "failure" case due to light leakage
Although the Samsung LCD TV of the Wuhan net friend Mr. Zhou's new home bought for more than half a year, the first time he watched, he found that the TV screen had been seriously leaked. He dialed Samsung's after-sales phone for repairs, but the result of onsite inspection was "normal." 
Mr. Zhou's photo of "light leakage"
The “leakage photo†taken by Mr. Chou shows that after the TV LCD screen is turned on, the four corners of the screen display a large group of white light, and account for almost one-half of the screen area without TV signal input. Prior to this, he called Samsung to report for repair after sale. The result of on-site inspection of the after-sales staff was "normal." (This case comes from the network, the original title: 15,000 yuan Samsung LCD TV screen leakage severe after-sale testing is normal).
Samsung TV leak how to do
If Samsung LED LCD TV light leakage phenomenon is not too serious, then we can reduce light leakage by appropriately reducing the brightness, LED TV is characterized by high backlight brightness, white dazzling. Obviously, the brighter the backlight, the more light is leaking. Therefore, backlight adjustment must be performed. However, this adjustment may not be found in the regular menu.
In general, LCD TV backlight adjustment is located in Home/Settings/Advanced Settings. Lower the backlight from 100 to 0-20 while adding a bit of regular brightness and contrast.
Leakage phenomenon detection method of liquid crystal television
Before purchasing LCD TVs, we can measure the technical parameters of TVs by using three basic TV colors: red, green, and blue. Based on the particular characteristics of LCD TVs, we should start with red, green, blue, white, and black. A variety of colors to examine the quality of the product, so that in addition to understand the basic parameters of the situation, but also to avoid the purchase of your product has a bad spot, bright spots, dark spots, light leakage and other unnecessary trouble. 
Samsung LED TV light leakage is how is it? Especially at night, when the television shows a black screen, there are bright lights in the four corners and the center, and it looks very uncomfortable. Is this a quality problem? Can I ask the manufacturer to change the TV? Or how to make it so that the TV does not leak light. In response to this series of questions, today I will give you detailed and detailed answers.
