An under cabinet led strip cut. Just slightly, on the side. There are three "wires" inside the strip, and one is cut. So now the leds starting from the cutting until the end side of the strip do not work. If I manually keep the two side of the cut "wire" togheter, the entire strip work fine. Using adhesive tape does not look like it can hold the broken "wire" in the perfect positioning for long. Is it possible to solder it? Or are there any other techniques to fix the strip?
