What's the reason for this? Please read the following post on the causes and failure analysis of the lcd tv screen, along with hubeda。

The user menu is normal, except for the image's screen phenomenon. The problem is usually on the computer board and scaler's processing chip. This can be determined by the maintenance worker, by pressing the chip, to see whether there has been a significant change in the screen screen phenomenon or, if so, whether the chip has been welded, by heating the ic with a special tool, such as a hot wind gun, which will allow uslding of the bad foot。
If the stripes and colours of the flowers do not change once the screen is up repeatedly, the screen itself is broken, and the drive screen is changed。
Lvds plugs are often in poor contact if the screens fail with the screens and the time is uncertain. This is when you clear the connection。
If the user finds a change in the stripes and colours of the flowers after the television screen has been re-powered, it is generally the drive plate that fails and replaces the drive plate。
1. Video-line issues。
Resolution issues. First, the video wires are replaced and, if not, where the computer resolution is changed, the lcd tvs generally have their nominal resolution, for example, 1366 x 768。
Some parts that may cause electromagnetic interference are removed from the card as far as possible (e. G. Hard disk) to see whether the screen is missing. If the electromagnetic shield function is determined to be a graphic card, it should be replaced, or a homemade shield。
These are the reasons for the appearance of the screen and a brief description of the trouble analysis on the tv, which disrupts the rhythm of our lives, so friends who know why have to ask the maintenance master to do it before we delay watching tv. In conclusion, we would like to remind you that, even if you know why, you must not do it yourself, in order not to create a situation that is irreversible。
