Television is a good tool for us to entertain at home. From the era of black and white to the age of intelligence, it has been accompanied by generations, but televisions have also failed. What about the tv? What's the method of repairing the failure? Study it together。
The so-called television screens are usually imaged on the screen, but they're a little bit of a stylish, and they're interference by marseilles. The components of this failure are the formation of the logical plate, the liquid crystal screen, the ttl or the lvds signal on the computer plate (mostly the ttl signal on the small screen, most of the lvds signal on the large screen, hereinafter referred to as the lvds signal)。
In repairing this failure, a distinction must first be made between the fault in the logical plate and the liquid crystal, or in the lvds signal section of the computer board. Opens the user menu and looks at the television screen to see if the user menu is accompanied by a television screen failure. If the user menu is normal, only the image has a screen. Problems usually occur in the break-up of computer boards and in the processing of chips by scaler. It is generally judged by welding (in the case of a bga chip, we can press the pressure chip and see whether there has been any significant change in the screen screen phenomenon, and if the change is apparent, it is usually caused by the chip's welding, with special tools, such as a hot wind gun, heating the ic and re-welding the bad foot)。
If you open the user menu, the menu on the screen also has a screen, which can only be judged by replacing the computer board and the logical board. The screen suffers from varnish and irregular flair failure, often due to poor lvds plugs. Cleaning the connection. Most of the high failure rates on the logboard are due to power circuit damage on the logboard and the scarcity of data and components. It can only be replaced as a whole at this stage. If there is no obvious short circuit on the logical board, the insurance can be replaced to observe whether the malfunction is eliminated。
We believe that, through the above analysis, you have an understanding of how the television screens are broken, and we hope that you will achieve something!
