The tablet will not power on, or it will not stay powered on as long as expected.
Charge the battery overnight to make sure it starts with a full charge.
If the battery had enough time to charge but the tablet still has insufficient battery power, the charging cable may not have been seated properly. Plug it in again, making sure the cable is in full contact with the charging port on the tablet and the plug is in full contact with the wall socket. Battery status (charging) and percent remaining will be displayed in the top right of the screen. Allow it to charge overnight.
If the above methods do not help, the charging cable may be faulty. Buy or borrow a different charging cable to test it. If the tablet still does not power on, the battery may be faulty.
If the tablet’s battery still does not work right after the above steps, the battery may be faulty and need to be replaced. Use the battery replacement guide located here.
The screen does not respond to the touch of a finger or the stylus in any way, it responds sluggishly, or the response lags.
Press and hold the power button on the right side of the tablet and select Power off, then confirm. If this does not power off the tablet, press and hold the power button until the tablet turns off (approximately 10 seconds). Restart the tablet. If this is a repeated problem, make sure your tablet’s OS is updated to the latest version. The latest software version for the LG G Pad X 8.3 can be downloaded at this LG Help page.
If you only notice problems when using the stylus, it may be faulty. Replace it.
If a reset does not fix the problem or the tablet’s screen noticeably lags, a screen component may be to blame. Use this guide to replace your tablet’s screen.
If the tablet does not seem to be turning on at all, the reason for your black screen may be the motherboard, which controls many processes in the tablet. Check out the motherboard replacement guide.
The sound coming from the speakers is too quiet, is concentrated only on one side when tablet is held in portrait mode, or is weak and tinny.
Check the Sound Profile in the Sound menu. Ensure that the tablet is not set to Silent or Vibration mode. If the sound is missing only in one app, check that app’s menu for sound settings and make sure sound is turned on.
Speakers are in landscape orientation on the back, producing sound on only one side when tablet is held in portrait mode. Use an external speaker.
The sound may be tinny, distant, or crackle at loud volumes. Many tablet speakers are small and not very powerful. Use an external speaker.
Speakers that do not produce any sound or produce sound with significant distortion can be replaced using this speaker replacement guide.
Photos show spots, are grainy in low light, or are distorted.
Clean the glass over the lens with a gentle solution, such as eyeglass cleaner, and a lint-free cloth. If debris has gotten inside the glass over the rear-facing camera, see this guide to disassemble the rear-facing camera and gently clean the lens as above. You can also tap the screen with the back cover off (after disassembly) to shake loose any particles from the lens area.
The rear-facing camera is especially prone to this. Increase ambient light by adding more artificial lighting to your subject or shoot in a better location with more light or during a brighter time of day.
If photos are distorted, the camera may need to be replaced, especially if the lens is cracked. To replace the tablet’s rear-facing camera, see this guide.
Apps that save to the SD card are interrupted, a sound plays frequently as the SD card connects and disconnects, files are not saved to the SD card, or files are corrupted when saved to the SD card.
Gently wipe the gold connectors on the SD card with a lint-free cloth to remove any debris that may have accumulated.
Eject the SD card by going to Apps>Settings>Storage & USB and then click the eject icon. Press the SD card inward until it clicks. It will then slide out. Make sure the card is facing the correct direction (when looking at the rear of the tablet, the gold strips on the card should be facing up) and insert the card again.
Back up your data first: this step will delete the data on the SD card. Reformat your card by going to Apps>Settings>Storage & USB. Tap SD card>Menu>Settings>Format. Confirm your decision. This resets your SD card to factory settings.
Download and use LG PC Suite from the official LG website to fix internal errors caused by updates. Follow manufacturer instructions. If the problem persists, reformat the SD card as in the previous step and try again. Always eject the card in Settings before removing it from the tablet to help prevent corruption (eject the SD card by going to Apps>Settings>Storage & USB and then click the eject icon).
