When half a string of Christmas lights goes out, first, check if any bulbs are loose and tighten them. Next, look for obvious signs of damage like broken or missing bulbs and replace them with new bulbs. If these steps don't work, use a light tester to find faulty bulbs. Once identified, replace the faulty bulbs. If the problem persists, the issue may lie in the string’s wiring or fuse, in which case checking the fuse or replacing the entire string might be necessary.
