LED Christmas lights - not working (Manor Park - Rockcliffe Park)

Multi colour lights (blue, green, yellow, red) might be one set that is just blue and white. One set is the larger size bulbs the rest are the smaller size. Outdoor. The lights are at most a year old and the wires not chewed so might be a fuse issue ? If anyone is handy and wants to see if they can get them going - you are most welcome. Let me know I can give an address and fine with porch pick up.
