SOURCE: Remote does not open garage door
It sounds like the wall button has the lock feature engauged.
Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

If you have to hold down the button to close the door, you are bypassing the sensors ...
Check the alignment of the sensors. Should see a solid GREEN light

This web address came from the Chamberlain site. I also needed to relearn my remotes due to a newer car that has a built in garage door opener that needed to be set. I also needed to reset my keypad remote, those instructions I was able to get from the same site. Good Luck

We had he same issue and changed our bulb from a CFC back to a traditional bulb and the problem was solved!

Tips for a great answer:
Open the garage door fully by pressing the wall control button. The bottom section of the door should be right at the header in the "full open" position. If it is too far back, the door cable can become misaligned. If it is not back far enough, you may not be able to get your vehicle in and out of the garage.
Position a stepladder behind the garage door opener motor. Locate the limit adjusting screws on the left side of the motor housing. Have a friend stand by the wall control button.
Insert a screwdriver into the slot for the "up limit" adjustment screw. Turn it to the right to decrease the door travel and turn it to the left to increase it. Turn the screw in small increments.
Close the garage door by having your helper push the wall control button. Notice the seal between the door and the floor--there should not be any light coming through. Adjust the "down limit" screw in the same way if necessary.
Operate the door by the pressing the wall button and check your adjustments.
