Cut the power

Table or floor lamp — pull the plug. Wired-in ceiling or wall fixture — flip the breaker and confirm it's dead. Then set the plug (or your eyes on that breaker) where you can watch it the whole time. Yes, this is Step 1 for a reason. I'm serious.

Strip it down — bulb, shade, harp, shell

Take out the bulb, then remove the shade and any glass. If it's a table lamp, lift off the lamp harp too — that's the bowed metal frame the shade clips onto — so nothing's in your way and nothing can break. Now find the word "PRESS" stamped into the metal socket shell near the base; press firmly there with your thumb while rocking the shell upward, and it pops loose and slides off. (Some sockets skip the PRESS shell and hold on with a small set screw instead — just unscrew or loosen it to free the shell.) Underneath is a cardboard insulating sleeve — save it, you'll need it. Slide that off too.

Photograph the wiring before you touch it

With the shell off, you can see the socket screwed onto the two wires at two terminals — one brass/gold, one silver. Take a clear phone photo now. This one habit saves you every time: it's your map back if anything comes loose, and it settles any "wait, which wire went where" the moment it comes up.

While you're looking, learn the rule you'll use in Step 6. Your cord has a smooth half and a ribbed half (little ridges you can feel, sometimes a printed line or text) — that ribbing marks the neutral wire. Ribbed/marked → silver screw (neutral); smooth → brass screw (hot). Getting this right means the switch cuts the hot wire and the outer shell stays neutral — safer to touch when it's on.

Remove the old socket

Loosen both terminal screws and unhook the wires, then lift the whole old socket free (unscrew the cap from the lamp pipe if it's threaded on). Keep it — that's your store reference for buying the exact replacement.

Now prep the freed wire ends. If the copper's corroded, blackened, or frayed, snip it back and strip a fresh 3/4 inch. Twist each set of strands tight so no whiskers stick out, then bend each end into a small J-shaped hook with needle-nose pliers — you'll loop these clockwise so tightening pulls them in.

Mount the new socket

Grab your matching replacement. If it comes apart, thread the wires back through the socket cap first and screw that cap onto the lamp pipe so it's seated firm and square — do this before wiring, or you'll have to undo your connections to fit it. (Forgetting is a rite of passage. You'll do it once.)

Wire it up by polarity

Time to use the rule from Step 3: ribbed/marked wire → silver screw, smooth wire → brass screw. Slip each hook clockwise around its screw so the loop closes as you turn. Seat it fully under the screw head with no bare copper poking past.

Tighten the terminals

Snug each screw down firmly — this is the connection your whole repair rides on, so don't leave it finger-tight. Give each wire a gentle tug; it shouldn't budge. A loose terminal is the number-one cause of a flickering or dead lamp down the road.

Reassemble

Slide the cardboard insulating sleeve back over the socket — do not skip this, it's what keeps the live terminals from shorting against the metal shell. Then slip the shell on and press until it clicks into the cap. Refit any shade or glass. You'll hear and feel the shell lock home.

Bulb in, power on, test

Thread in a bulb of the right wattage, restore power, and flip the switch. Let there be light. If it works — congratulations, you just fixed something with your own two hands. If not, cut the power again and jump to troubleshooting below.
