I would suggest following the steps in a different order:

remove bottom trim

remove diffuser

then remove the bulb & socket, and the 4 screws from the bottom which will allow access to the main board.

Hi,

The guide was very helpful as I just received such lamp for checking from one friend.

I would make only make one correction: you do not have to cut the plastic snap-ins, none of them.

If you use an IPhone opening toll kit, with those plastic levers as here:

[produto vinculado ausente ou desativado: IF145-000]

then you can open it easy, without any scratches.

Excellent guide. I did, however, not have to cut off any off the plastic snap-ins from step 9. Used a bigger screwdriver and gently used a bit of force, and one-by-one they came off.

Thank you so much for this guide. Was just about to give up on my lamp and buy and inferior led version when I found this.

These steps also work for the 3740 but the tabs holding the shade on (steps 8-10) are a different style. More like the ones on the bottom trim piece. Had to really work them and muscle that part off.

My ceramic bulb holder is severely corroded to the point where the light will only turn on if you jiggle the bulb. A little sad to see that the wires going to it are permanently attached on both ends. Now that the whole thing is apart. I'm going to see if I can source a new bulb holder and splice it onto the top...
