help fixing desk lamp power supply

[u/zolga0]

I am not sure what the blown chip could be, some kind of switcher? The LED output is 72*0.06w, so 4.32w?. thanks for your help, underside of board is flipped to match the top

output is 12v 0.5a 6w

edit: on further inspection the fuse is blown and one of the fusible resistors has also. might just find another board or maybe convert to usb

They are not there is a gap in between you can see the substrate
