LG enV VX9900 Troubleshooting

Your phone's power will not turn on.

To turn on the phone, press the indicated power button. Make sure to hold the "on" button, not just press.

If your phone is unresponsive when attempting to power up, your battery may be uncharged. To fix this, plug in the power adapter into the phone and charge the battery. If the problem persists, the battery may be unable to hold a charge and would need replacing. Please refer to the Battery Installation guide here.

If the battery is known to be charged, or the phone is being externally powered and the phone still won’t turn on, there may be an issue with one of the circuit boards. Either of the two main circuit boards may need replacing. Please refer to this Circuit Board Installation Guide.

Either screen on your phone will not operate as intended.

If either screen on your phone will not display anything, the screen may be broken. Try restarting the device (turning it off and back on via the power button). If the problem persists, you may need to replace the screen. Please refer to the LCD Screen Installation guide here.

If the screen has areas that will not produce the correct colors, or are not as bright as the rest of the screen, the screen likely has some dead pixels. The only way to repair these is to replace the screen. Please refer to the LCD Screen Installation guide here.

The phone is not receiving a signal and therefore cannot send or receive calls.

If you can't receive cell phone service, the antenna may be broken. Please refer to the Antenna Installation Guide here.

If the antenna is not faulty, your service provider may not be correctly providing service, or your phone has not been set up by the company to be used under their service. Please call your service provider in order to either find the error or set up your phone up for service.

Photos taken by the phone have visible cracks or other blemishes.

If the exterior protection for the camera is scratched or dirty, first try cleaning the exterior lens gently with a microfiber cloth. If the problem persists, you may need to replace the exterior case.

If the previous step does not solve the problem, there may be an issue with the camera itself. The interior camera may have been scratched or broken and may need replacing.

The phone is unresponsive to keyboard use.

The keyboard is the collection of buttons which is revealed when "flipping open" the phone and shows primarily the English alphabet. If the keyboard isn’t working properly and does not register any input, the keyboard may need to be replaced. Please refer to the Keyboard Installation guide here.

The phone is unresponsive to keypad use.

The keypad is the collection of buttons on the front of phone while it is "flipped closed" and consists of the standard phone buttons (0-9, #, *). If the keypad isn’t working properly and does not register any input, the keypad may need to be replaced. Please refer to the Keypad Installation guide here.

When trying to play music over headphones, either one or both of the headphones do not produce sound.

First try unplugging the headphones from the device and plugging them in again. If the problem persists, you may have a broken plug that needs replacement.

The plug may have disconnected from the circuit board or otherwise broken. To fix this, the circuit board may need to be replaced. Please refer to this Circuit Board Installation Guide.

If both the connection is good and the plug is not broken, then the headphones themselves may be broken. In this case, you will need to replace them.
