Check the resistance down button (There is one for down and another one for up). You may need to adjust the sensitivity. That way even if for some reason the have hard time coming down, less sensitivity may solve that issue.
Great call Marty! I had noticed the amber LED above the learn button was blinking with one pulse, which the troubleshooting guide noted as being a problem with the sensors.

Have you tried it in the dark? There is a photo sensor that is located just above the right soft-key. It looks like a pin hole.

The purpose of this sensor is to prolong the battery life by not having to light up the keypad in the daylight.
There is a way to disable the photo sensor so that the keypad is on whether it is day or night. Look for a setting that allows you to turn the "battery saver" feature off.
1 of two things: Go into your settings and look for either "Keypad" or "Display" and see if keypad lights are set to ON.
2. Your phone does have a light sensor built into the keypad, normally the keypad will not illuminate unless insufficient lighting conditions are present. If it's pitch black out and the keypad still isn't illuminating and your settings have the keypad lights ON .... You should bring your phone to the nearest Verizon wireless corporate store to see about either replacement or upgrading.
