Is the lamp new? Look at the bulb to see if the glass has turned black, and if it turns black, the bulb burns out! The socket that plugs in the bulb has electricity or other sockets a little!
If there is electricity in the socket where the bulb is plugged in, it is undoubtedly a bulb problem! If there is no power, it is a wiring problem, or maybe the wiring is aging. It's also possible that the line burned out!
