When the notebook computer has a splash screen, due to the screen flashing, not only affect the normal use, the eyes look very uncomfortable, today this article will talk about the causes and solutions of the laptop splash screen.

      First, the screen caused by the backlight splash

       Failure performance: Notebook backlight flashes occasionally, frequency is very fast, sometimes flash several times, sometimes it lasts for several minutes.

       This occurs because the high-voltage board that supplies power to the backlight of the screen is not stable or the connection of the solder joint at the lamp connector is not firm. The screen flash caused by the high voltage board can replace the high voltage board to solve the problem. In our daily maintenance, sometimes for the original high-voltage board price and supply reasons have to be modified through the general purpose high-pressure board to achieve maintenance purposes.

       The long screen flash time caused by the false weld at the lamp joint is more serious. Look closely at the lower left corner or the lower right corner of the screen for a small piece of black shadow. This is the spark caused by the joint welding. Burned. It is also not possible to remove this small piece of shadow after repair.

       Second, the motherboard splash screen caused by the charging screen

       Failure performance: When the battery and the power adapter are used at the same time, the notebook will occasionally display a screen flash. At the same time, the charging indicator in the lower right corner of the screen will stop switching. When a single power supply is used, the fault disappears.

       This failure is relatively rare in notebook maintenance, mainly due to the instability of the components of the battery switching circuit on the main board. Repairing the components of the main board charging circuit can repair the fault. Another situation is due to the quality of power adapters. We hereby advise you that the power adapters should be as original or as good as possible. Do not rush to use tens of dollars cheaper power. This kind of power is held in your hands. The materials used are as expected.

      Third, the screen itself caused by the screen flashes

       In fact, the flicker of the notebook screen caused by this reason in recent years occupies a large proportion. The reason why it is put in the end is because this situation is limited to the same batch of several models of notebooks. The specific fault performance is: generally there will be a bright line at the bottom of the laptop screen. It will not be long before the bright line will evolve into full-screen flashing.

       There was a period of HP "flash screen", mainly because it used the LG Philips LP141WX3-TLN1 batch of screens, there are hidden dangers, may cause splash screen, the specific model: HP541, HP540, CQ45-307TX , CQ40-406AX, dv4-1213, DV5-1218, DV2211TX, DV2621, CQ40, DV4 1212TX, 6531S, CQ45, 6535s, CQ45307TX, CQV3239AU, V3159AU, 540(259), V3803TX, CQ40-406AX, DV4-1213TX, CQ40 -403AU, HP 541, V3907, CQ40-414AX, DV2-1005AX, hp520, CQ45-307TX. Among them, CQ40, 6531S, CQ45, 540, 541 and other models are the most common. All are used LG's screen. Lenovo also has a small number of notebooks with LCD screen quality, the main models are: SL400, Y430, Y460, G430, R400.

       This situation can only be replaced with a new LCD screen.

       As can be seen from the above, the notebook splash screen is mainly caused by both the manpower and the quality of the notebook itself. The machine itself cannot be decided, but it is still recommended that when using the laptop, try not to operate in violation of the rules, and use it normally. Maintenance can minimize the problem of splash screens on laptops.
