Overtightening 3-way bulbs will deform the socket contacts and cause
the problems you are having. The quick fix is to disconnect the lamp,
remove the bulb, and pull the contacts gently up with needle nose
pliers, or similar handy device. Reinsert bulb with less force, plug
in lamp and the system should continue working properly for a long
time. HTH
