Repairing Lamp Plugs
Don't overlook the obvious: no power or a bad bulb. Try a new bulb and plug the lamp into a different outlet before taking things apart!
Before you begin be sure the lamp is disconnected from the wall plug.
REMEMBER!! Be sure none of the little strands from one wire touch the other wire or you will have sparks when you plug it in.
A new plug (clamp type) is easy to use.
