i think they work on a loop type thing so if one is no good it knocks the whole row out i had the same problem and id put to much heat into one of the tiny copper pads its solders on to and literally burnt it away, i took it to an electronics specialist and he managed to strip some of the coating back off the board and fixed it for free then the whole row worked, so its prob only one thats your problem could be faulty led or bad connection

I changed one at a time and checked them each time to make sure they still worked. They daisy chain into each other so if one's not right it knocks out that whole chain.

sorted it was a led where the neg and positive where the wrong way on the led so had to make a tester wire and a battery and go through all the leds and found it.
