I wonder if you have any ideas on how to fix my LG 5450. It works fine except that it does not recognize the service in the area - only sensing one or two bars in full service areas and elsewhere searching for service until it shuts off or the battery goes dead! We can't find the problem. We have tried resetting the factory defaults, examining the phone carefully for defects and sent for repair quote with only comment that they would have to change whole board for 299.60! More that I paid for the phone. I don't really believe in a throw-away society and think there must be a practical way to repair the problem. It happened after I travelled out of the area and used an antenna purchased specifically for use for this phone. Of course, the phone is just over one year old!
Thanks in advance for your help!
