Why the problems still persist after screen replacement?

  If you dropped your smartphone, your touch screen may have some tough problems. A cracked display is one of the most obvious signs of a damaged screen which may cause all sorts of problems. The delicate layer is susceptible to damaging. After you finished the LCD screen digitizer replacement, there still will have some side effects and subsequent issues if you buy a poor quality screen digitizer parts. The most common issue is a dim screen. Your first action is to reboot this unresponsive smart device. Let us take a look at the reasons behind the dim screen.

  The root cause behind this issue is damage to the backlight circuit behind the screen. Ordinarily, this component is not easily damaged; however, some screens have an exposed backlight solder joint on the flex cable. This is especially true of low quality screens. During the reassembling of the phone, the backlight circuit can get shorted, resulting in the aforementioned screen dimming. There are a few other causes discussed below. What can be done to rectify the problem? The first thing to do is to ensure that you are using a genuine component to replace your old screen. It is best to use a genuine, Apple approved screen; as this drastically reduces the chances of the screen dimming problem occurring. There are high quality third party screens available. Make sure you do proper research before choosing a replacement screen. Examine the iPhone’s circuit carefully for signs of damage, especially the micro ribbon plugs. Burnt connections from the screen assembly to the motherboard can sometimes cause the dimming issue.

  One other thing you can do is to replace your backlight circuit with the one from your old screen. This will serve to resolve the problem temporarily, but if you are replacing your iPhone’s screen, chances are there is already something wrong with your old backlight. One obvious iPhone dim screen fix is to ensure that the brightness has been turned up in the iPhone’s settings, since screen replacement can sometimes reset the screen brightness. Certain accessibility settings can also cause this issue. This sometimes happens after iOS updates. If this is the case, it can easily be rectified by opening the Settings app and navigating to General -> Accessibility -> Zoom and disabling Zoom.

  A malfunctioning light sensor can also cause this problem. One way to identify this is to reboot the iPhone and observe the brightness of the Apple logo. If the Apple logo is bright, but the screen dims on boot, the problem is due to a malfunctioning light sensor. Repairing or replacing it will fix the issue. You can also try reseating the iPhone’s camera sensor, light sensor and speaker and see whether it fixes the screen dimming. If backlight circuit is the culprit behind your screen dimming as discussed earlier, you need to examine the backlight circuit, find the dead filter fuse and replace it. As always, do not attempt board level repairs if you are unsure or lack the necessary tools or knowledge. If your screen dimming persists even after trying all of the above, it may be best to take your iPhone to an Apple store or third-party retailers for replacement or repair.
