how do you repair led christmas lights

*Elf smiles as the Repair Elves continue working on the broken lights* "Repairing LED Christmas lights is a bit more complex than traditional incandescent lights. The problem could be anything from a loose connection, to a blown fuse, to a faulty component. The elves will need to carefully inspect each light strand, looking for any signs of damage or malfunction. They'll likely use specialized tools and equipment to test and diagnose the problem, then perform the necessary repairs."
