What Cause the iPad LCD Screen Backlight dim and How to Fix it

This is a problem our customers complain about most in our shop. Some new replaced LCD screens are dim when we turn on the iPad. The same problem has happened on iPhone screens before, and we consume the issue to be the backlight circuit problem. How could this happen to the LCD screens? Can this problem be fixed? Here we would like to discuss it with you here.

Firstly, we have to know something about an iPad or iPhone LCD screen’s composition. The LCD screen is totally consists of eight layers, but only the three layers related closely to the image forming and animation on the screen. The backlight is one of these three layers. It is an LED light panel that allows the phone screen to be seen in the dark. When this light panel fails for lighting up, you will see a very dark screen and dim images, which can only seem under strong light. The reasons why this happened are complicated. For one side, some of the low-quality LCD screens are manufactured from third-party factories. These high copy screens are not matched with the original screens on the electrical characteristics. The high copy screen requires much more electric power loss than the original screen. When the backlight circuit is overloaded, it would be damaged and not work. On the other side, damages to the iPhone or iPad screens may cause the iPad screen backlight panel to fail for lighting up after iPad LCD screen replacement.      

Next, fixing the backlight circuit issue can be difficult and risky. It requires someone professional on Apple mobile device repair experience on it. Since the backlight failed for lightening could be more than one reason, the repair solutions consist of a simple filter replacement, another can require replacing the whole circuit or adding jumper wires to bypass damaged tracks. Specifics of the operation may refer to YouTube videos or google. We advise you not to try without professional guidance because these solutions are risky. Inexperienced operations may cause irreversible damages to the new screen. You may check our iPad repair guidance about iPad mini 4 screen replacement video if you have interests.

Finally, we sincerely advise our iPad and iPhone users don’t trust any “parts swapping fixing everything” from a third-party repair shop. Choose the original new LCD screens or high-quality level screens for replacement if you have to swap the original screens. All in all, we should take action for our iPad screen protection or else it will cost us a lot on repair. Besides, you may come to Etrade Supply online store for our new iPad swappable screen.
