When the winter is fine, the weather gets hot after a period of time will appear below the screen white stripes. The first one is very thin, and then gradually widened, and finally about 8 mm will not change the way, if the monitor off, and so on, he cooled, in the open is good, after the heat is the case again
A horizontal or vertical line of liquid crystal display is part of the LCD display.This situation can only be returned to the factory maintenance. The rate of repair is very small, and it will be easy to recur after repairing for a period of time, and the cost of restoration will be high.Recommendations: in the period, can repair, businesses will give you unconditional replacement of a new display. In case of insurance, it is recommended to re purchase and replace a monitor. If the fault monitor does not have many bright lines and does not affect the normal use, you can use the bright line until you can't use it to replace the monitor.
The liquid crystal display is composed of a liquid crystal module, a drive circuit board and a shell, and the liquid crystal module is composed of a liquid crystal screen and a backlight, because the liquid crystal screen itself does not emit light and needs a light source to illuminate the screen. LCD screen is hardware, if there is a fault, disconnection, the phenomenon is irreversible, irreversible. The backlight is LED or CCFL light source, plus optical film material (make light walk more evenly) of the mechanical structure, closely attached to the back of the LCD screen.Is your problem, back light source on the optical film material due to aging, and the mechanical structure and the backlight module fit is not very strict, in the days when the heat deformation caused by thermal expansion and contraction, light out of the uneven distribution, resulting in the exterior looks like a white bar.If the fault needs to be repaired, it needs to get the dust-free workshop of the liquid crystal module factory, disassemble and replace the backlight, and the time and cost are relatively large.If you really affect vision, it is recommended that the landlord replace the monitor, the cost of maintenance is relatively large; if you have not seen the warranty period, find JS to replace the new monitor.Any further questions, please feel free to contact us
Display aging, quality can not be done.
