The LG L1400 is a mobile flip phone released on the Cingular network in 2004. Though it will work without problems in most instances, there are times when the L1400 does not operate as intended. Most problems are common, however, and can be fixed without the need of a service technician by troubleshooting and fixing the phone yourself.
Connection Problems
You may find that the L1400 is not audible or does not receive a signal when trying to make or answer a call. This occurs when the phone is not in the range of a cell phone tower or there is some electronic disturbance. You can often regain a signal if you move to another location.
In rare instances, the L1400 will not work if there are too many users on the network. You may need to wait several minutes before you can use the phone.
Blank LCD
The LCD screen on the L1400 may not work on occasion. This is often a power issue and can be fixed by removing and reinserting the battery. The battery is located in the compartment in the back of the phone. To remove the battery, flip the phone over so the back is facing you. Hold the battery cover lock on the top of the phone. Push the cover toward the top of the phone and pull it off to expose the battery. Take the battery out of the phone and reinsert it. Place the cover back on the L1400, pressing down until it clicks in place.
If the LCD is still blank, the battery may be drained. Fully charge the battery before trying to use it again.
Short Battery Life During Normal Use
Battery life is determined by the way you use your phone. If you use the phone often to make phone calls, send text messages or play games, the battery will drain faster. There are times, however, when the battery will drain faster during normal use. If you are making calls over a weak signal, the L1400 works harder to keep the connection strong enough to transmit and receive a signal. The power used to keep the signal will drain your battery faster.
Short Battery Life in Standby Mode
You may notice over time that the battery does not last as long, even if the phone is not used often. The L1400's battery will wear down after extended periods of use and recharging, and will not be able to hold its charge as long as in the past. You should replace the battery once it keeps the charge for approximately half of its normal time.
