Electrical issues with the battery of the device due to age of model and overused battery capacity.
If the LG X Power will not power on or show any sign of charge unless it is plugged, you will need to try to exchange the battery for a new battery. This may be caused by overuse or leaving it charging too long.
The way to do that is by first opening the back cover of the phone by using one of the metal spudger's from the set. You can start from the bottom of the phone and put the spudger between the back cover and the side to open up the back. Then you can take out the battery and replace it with another battery.

If the phone is plugged into the charger coming from a computer or laptop and is not displaying the charge light in the top-left corner, first check the charging settings in the phone and make sure that it is set to charge and not file share. If the the phone is plugged into the charger directly connected to a wall outlet, then it could be the charging port is not properly working and will need to be replaced. This could happen by incorrectly plugging it in or even a faulty charging cord could affect the device negatively. You might need to replace the charging adapter using this guide.

When you go to your camera app and the only thing displayed is a black screen or an error code, the camera will definitely need to be replaced. Use this guide to do complete the task. This may be because the camera was damaged from overheating or water got in the camera.
The way to replace the camera is by first opening the back cover of the phone. Once you got it open, the cover you will be looking at the battery, remove the battery and remove the cover as well. After that, you will see the camera on the top right, remove it carefully (to remove the cover and camera click here).
Then you can replace it with your new camera.
If you are trying to take a picture and your camera is unclear or looks foggy, it could be the auto-focus setting in the camera settings. To fix this, go the camera settings and check to make sure that the auto-focus is turned on or you could manually focus the picture by zooming in and out and tapping the screen until the picture is clear. This could also be because you entered a really hot place or extremely humid environment that damaged the lens or even parts of the camera. In addition, you may have gone swimming and the phone could have been in contact with water at some point and this could be the cause.
Follow the same steps in previous guide to replace the camera.
Problems with audio port and speaker because the connection or faulty parts.
If headphones with a wire cord will not function properly or at all and is only working correctly with wireless connection via Bluetooth, first check the cord and make sure the wire is not damaged in any place or even bent too much. This could be the cause of any static noise or it not working. Also, check the inside of the auxiliary cord jack because dust or other build up could be a cause for issues. If that is not the problem, you may need to replace the adapter at the connection point.
