When the LG G6/LG G7 screen won’t turn on, at first, you don’t really understand what’s happening. Buttons light up as if the device is running, yet the display remains dark and still. You’re getting a call and you can’t take it because you can’t see anything on the screen – neither the name of the caller, nor the answer or end virtual keys.
You leave your phone on standby for a while and then, when you try to unlock it and use it, you can’t, because it acts just like we described above. This is a common problem that happens to many LG G6 and LG G7 owners on different occasions.
For these reasons, we have decided to put together a troubleshooting guide that will help you fix LG G6/LG G7 screen won’t turn on problem. We’re going to approach three different solutions. But if none of them works, you will really have to get some kind of technical support. An authorized technician from a service will have the tools to fix it or, in any case, the power to replace your phone with a new one in case it cannot be fixed anymore.
Nevertheless, let’s don’t jump to conclusions and focus on what you can do on your own, for now.
Solution #1 – hit that Power button
We know, by the things we just described, it looks like the device is unresponsive. But what if you’re dealing with a broken Power button? Or maybe it’s stuck. Press it several times in a row, softer or harder, until you make sure that the button acts normal and you can move on to suspect something else.
Solution #2 – boot into Safe Mode
By suspecting something else we mean accessing the Safe Mode and trying to spot the problem in there. This mode relies exclusively on a couple of pre-loaded apps. If it was a third-party app causing your device to block, it will no longer manifest in the Safe Mode. That’s one way to tell that you need to uninstall some of your third-party apps.
Speaking of which, the Safe Mode is also the place where you can safely remove any kind of app without worrying that you will damage your LG G6 or LG G7.
Since we assume that you’ll know what to do once you get in there, here are the steps on how to boot LG G6 and LG G7 into Safe Mode:
- Press the Power button;
- Hold it until the LG screen appears;
- Release the button;
- Press the Volume Down key;
- Hold it until the device restarts and you see the Safe Mode text on the screen, somewhere at the bottom-left corner.
Solution #3 – wipe cache partition
If you couldn’t solve anything from the Safe Mode, continue with the Recovery Mode. Once you switch to this new functioning mode, you will be able to wipe cache partition and, hopefully, fix the LG G6 and LG G7 screen won’t turn on problem:
- Start by simultaneously pressing and holding the Volume Up, Power and Home buttons;
- When the phone produces a short vibration, let go only of the Power button;
- When the Android System Recovery screen appears, let go of the other two buttons;
- Use the Volume Down button until you can highlight the Wipe Cache Partition feature;
- Press the Power button and wait for the wipe cache to happen;
- When it’s done, your LG will automatically reboot and switch back to the normal mode.
Here you have a comprehensive guide on how to clear cache on LG G6. And below you can drop us a comment in case you have any other questions that we can help with!
