I'll bet a pound to a penny, its the wires where it goes in to the straighteners, because they keep bending, they finally fray inside, go to e-bay, type in GHD Repair, and you will be able to buy the wire that goes in to them for 3/4/5 pounds, its easy to fix, as i have done it, so it must be easy, good luck.
