IT'S IS FIXABLE!!! I had the same problem with three different sections of my LED lights. What I did was to take out each unlit bulb and reinserted in a lit up area. Many times it still didn't work so I took out the unlit bulb, and pulled out those two little metal prongs on the side to make a better connection. Most of the time it worked and the bulb lit up. If not I just replaced it with a good one. I continued to do that until the whole section lit up. All three times it worked... I did like most of you did. I change the fuse, I pushed and pulled and twisted on each bulb, I was even ready to cut out the unlit section. But it's like the old saying/acronym...KISS... Keep it simple stupid. LOL. Good luck
