An inalienable disadvantage of absolutely any modern mobile phone, regardless of class and cost, is its low durability. This is especially true for glass on screens. The large area makes it extremely difficult to make it unbreakable, no matter what material is used. As a result, glass breakage is a common problem among LG phone breakdowns and may require OCA tape for LG or LG LCD backlight repair.
Not everyone knows that the bright light emitted by the screen of a mobile cellular is not the merit of the display itself, but its backlight. The latest technology for assembling mobile screens provides for their arrangement of two main components - the monitor itself, which does not have the ability to one- or polychrome glow, and a special frame lamp that illuminates the display surface and thereby makes the image visible. Undoubtedly, this is a fairly approximate description of the principle of displaying a mobile screen but it also allows you to find out that you won't be able to notice anything on it without backlighting.
LG LCD led backlight can burn out, stop functioning mechanically, or fail through something else. In any case, in the event of damage, its correction is extremely rarely advisable - as a rule, replacement is required. In some cases, you can only change the backlight itself, in others, you also need to replace the screen.
It can deteriorate after impact damage to the cell (for example, falling on a hard road surface, hitting a table or other object) or contact of the cell with moisture, and for this, it is not necessary to completely drown it in water - it can stop functioning due to dew, rain and then LG LCD backlight replacement is required.
