You watch your favourite movies, series, cartoons, news and sports on your TV. However, sometimes you encounter the problem of dark spots appearing on the TV screen.
Black dots on an LCD TV can disrupt the picture quality and viewing experience, especially if they are located in the centre. At best, black spots are caused by dirt, dust or debris that has accumulated on the surface of the screen. Dead or blocked pixels due to internal errors can result in black dots. Before resolving the issue, the best thing to do is to determine exactly what is the reason behind these black spots.
Reasons of dark spot TV
Common reasons that causes black spots on your TV screen are:
Dust
Dirt gets under the container. With improper maintenance of your TV screen, one small black spot can develop into a big dark spot, which can only be repaired only by a TV technician.
Before assuming that LCD spots are caused by internal malfunctions, clean the entire screen according to the manufacturer’s instructions and instructions in the user manual. Use a soft cloth and a 50/50 solution of water and alcohol to gently rub the problem areas and the entire screen. Never use paper towels as they are abrasive and will further damage the screen.
Moisture
Moisture or air getting under the protective glass. The reason is bad transport or wrong handling. Do not wipe the screen with water or a very damp cloth.
Temperature
The presence of a heat source near the device causes various malfunctions, including the appearance of spots due to delamination.
Dead or stuck
An LCD pixel has three red, green, and blue sub-pixels that can change colours and display each colour in 256 shades or grey levels. If a pixel is stuck closed at grey level 0, it will appear completely black. A pixel will also look black when it’s dead. If you see that the pixel can still change colours slightly from its usual black appearance,then it is stuck. Dead pixels can occur due to blunt force to the screen, transistor failure etc.
Manufacturing defects
It is quite rare and appears immediately on TV screens. The reason is a violation of the assembly technology, which leads to damage to the screen matrix. The warranty of the TV will take care of such manufacturing defects.
Mechanical damage
Any accident can cause a strong impact or pressure on the TV screen changing the colour of the CRT and cause a mechanical problem. Broken pixels first appear in the affected area and then spread across the screen.
