If there is no display backlight on the iPad, it does not affect the performance of the tablet, but it significantly reduces its usability. The absence of a backlight or its weak operation does not allow you to use your iPad in the dark or in bright sunlight - you simply can not see the image on the screen. This small disadvantage makes the tablet absolutely useless in most cases, but it is easy to solve this problem on your own.
LED backlighting is necessary for the comfortable viewing of texts and images on the tablet at any time of the day and in any lighting conditions. If the bulbs do not work properly, it significantly reduces the performance of the gadget. The bulbs are located under the display. Most often, the problem with LED backlighting lies in the settings of the tablet itself. Therefore, it is not necessary to immediately carry the device to the service center. This problem often occurs to Apple users, and you can solve it on your own by following our simple recommendations.
If the display backlight does not work, you can try to determine the cause and fix the problem yourself. The main reasons for the lack of backlight on the iPad of any model are:
If the cause is an incorrect brightness setting, the problem is solved very easily:
If there is no damage to the internal elements, the problem should go away.
If the brightness settings are fine and set at the settings you want, but the LED backlight is still missing, perhaps the problem lies elsewhere. Most minor malfunctions with Apple hardware can be solved with a hard reset of the device. So, if you find any malfunctions in your gadget, you should do a hard reboot right away. If there is no display backlight, this method can also be helpful.
To do this, it is necessary to follow these steps:
Most often, such a reboot will quickly resuscitate the faulty backlight. If this does not help and the problem persists, check if the "auto-brightness" function is enabled and update the tablet to a new version according to the manufacturer's instructions. Lack of updates is a frequent cause of many problems with Apple tablets. Therefore, you should update to the latest version every time the device prompts you to do so.
If the backlight is gone, the above tips did not help, and the image is also not visible, remember the last manipulation with the device. If the tablet is dropped, the light stops working, and the circuit is damaged, even if there is no visible damage to the gadget. The problem is solved by replacing the fuse.
Also, a problem with the LED backlight can occur after you have spilled something on the tablet, and the liquid gets inside, flooding the fuse. First of all, dry the device thoroughly, then restart it and try to adjust the light again.
Lack of backlighting after repair or display replacement indicates poor quality repair work. For example, you decided to replace the display cheaper with an untested technician who did the work poorly. You can't fix such a job without the help of a qualified technician.
Only a professional technician can competently solve such a problem if a hard reset of the tablet does not help and all the settings are set correctly. The master will make a diagnosis and determine the problem in the cable or fuse. In particularly complex cases, the display should be replaced.
