A TV is an essential part of everybody’s life, as without it, killing time will be a hard thing to do. TV time is also considered family time because, after a long tiring day, the entire family sits together and watch their favorite shows together.
The market is flooded with different types of televisions. Different technologies have been incorporated into TVs such as LCD, Plasma and LED, with LED TVs being the most recent one to be used in TVs compared to the other two. No matter how technologically advanced your TV is, it can malfunction at any point of time, causing a huge inconvenience to people who were about to watch their favorite content on the TV. Let’s discuss some of the most common issues in a TV.
This defect is popular in plasma televisions and its cause is because the cells burn and end up leaving marks of the scene that was previously on the screen. Normally, the defect appears when the image is displayed for an extended period of time.
Another annoying thing about this problem is when a movie smaller than the correct display size is displayed on the screen, then the edges will be visible later, hindering the reproduction of other contents. This also happens when leaving your TV on the same channel for several days; the TV logo may burn the pixels.
Dead Pixel, Hot Pixel, and Stuck Pixel
Television pixels can present a number of problems that hinder image viewing, one of the most well-known being the dead pixel. The main feature of this problem is when one pixel is erased while all others display the image normally. They often occur on televisions with LCD screens and can appear on either used or new products.
The hot pixel defect is opposite to the previous one. In this case, a small dot turns completely white on the screen. And finally, we have the stuck pixel, where a pixel has a single color, be it red, green or blue.
This defect causes an intense movement of the image and this constantly ends up in a longer delay in screen updating. It is a common defect in monitors, however, it can appear on television as well. Some situations in which this problem is perceived is when connecting the notebook via HDMI or VGA cable and even when using Xbox, PlayStation, Nintendo and other consoles on television.
You have noticed a different movement on TV when watching a video with a high amount of movement, usually when you have many people in the same picture. The image has a “ghost effect” in the background. The cause of this problem is that pixels, unlike Tearing, take a long time to display images, causing scenes to “ghost” on the screen.
Certain types of televisions have a problem identifying properly presented content. It is usually noticeable in situations where videos are cropped on the screen, i.e., images do not fit in the screen space. These are factory defects and usually cannot be corrected.
Lack of definition
This defect was common in older tube televisions, but some modern equipment may still have this defect. The problem arises when the television is forced to display content with a lower resolution than what was programmed to work by default. The lack of definition is nothing more than a certain number of cells being forced to display identical pixels, which results in more squared images.
What to do?
Now when you come across these flaws in your image you already have a sense of what it can be. It is recommended to always seek assistance with the maintenance of televisions.
