LG K30 troubleshooting

No matter what you do, you can't get your Phone to turn on.

If your Phone’s problem isn't so easily solved, read on.

If your Phone won't turn on, especially if it has not been used recently, you may simply have a drained battery. Plug your Phone into your AC (wall) adapter and see if anything happens. Ideally your Phone will recognize it has been connected to a power source and charge its battery. If it will no longer charge, the battery must be replaced.

It is possible that it appears nothing is happening because the display is bad. If the battery is working properly but nothing is visible, it is possible the display is bad and must be

Ultimately, if the display and battery are not the culprit, check all the connections from the display to the logic board. If they are connected properly and there is still no life, the logic board most likely needs to be replaced.

You open the camera, and you can’t see anything.

Simply exiting the camera, waiting for 30 seconds and then restarting the app by tapping on the app icon.

It’s possible that something is covering the outside of the camera, which is preventing an image to appear on the screen. Assure that your finger, case, or anything else is not blocking the camera from capturing an image.

A common cause of application issues is a software glitch. If the camera has stopped working without any reason, then restart the device.

It’s possible the physical camera lens is faulty or damaged. It may need to be replaced.

Your Phone turns on and appears to work, but when you plug in headphones or try to listen through the speakers, the audio doesn't play properly.

It's unlikely your headphones or speakers are bad, but it's worthwhile to eliminate these as the source of your problem at the beginning. Try your headphones with another device to make sure that the problem is with the phone.

The most likely cause of audio output problems on the Phone is a bad audio-out jack. First try a hard reset on the Phone to make sure it is not a software issue. If that fails to work, try replacing the audio jack or exterior speakers. If that doesn't solve the problem, your logic board most likely needs replacement.

You press the exterior buttons, but nothing happens.

Just turned it off and back on.

Although unlikely, if a case is on the phone, it may be blocking or making it difficult to press down the volume buttons properly. It is necessary to remove the case and attempt to use the buttons again.

The buttons might be damaged or faulty. They will need to be replaced.

The phone is turned on, but nothing shows on the screen.
