How To Fix LG G4 Black Screen

It’s common knowledge that when a smartphone is asleep or turned off, the screen is black. When you turn it back on or attempt to wake it up then, ideally, the screen will turn back on. Despite this, sometimes the LG G4 will have a black screen even after you have turned on the smartphone.

The problem is that the LG G4 buttons light up like normal, but the screen remains black and nothing shows up, as the screen fails to wake up. There are several different ways to try to solve the LG G4 blank screen problem, follow the instructions below to learn how to fix the LG G4 screen not turning on issue.

Boot to Recovery Mode and Wipe Cache Partition
The following steps will get the LG G4 into Recovery Mode:

  1. Press and hold the Volume Up, Home, and Power buttons at the same time.
  2. After the phone vibrates, let go of the Power button, while still holding the other two buttons until the System Recovery screen appears.
  3. Using the Volume Down button, highlight Wipe Cache Partition and press the Power button to select it.
  4. After the cache partition is cleared, the LG G4 will reboot automatically.
