1. Small amount of damage

2. If you have strong hands-on ability, you can go to the Internet to buy the same model of lamp beads (10 yuan a big bag) and replace them by yourself -- use electric iron (blow dryer for a while) to heat the old lamp beads until the glue on the back of the old lamp beads melts, and use tweezers to remove the old lamp beads (do not use your hands, too hot). At the same time, install the new lamp beads while they are hot (pay attention to the positive and negative poles), and you are done!

If a large number of beads are damaged, it is recommended to replace the whole bead board. Lamp bead board is also available on the Internet. Pay attention to three points when buying:
1. Measure the size of your lamp;
2. Look at the appearance of lamp bead board and starter connector (explain later);
