Yes, you can easily repair fuse LED bulbs. In a LED bulb many small LEDs connects in a series format. So, the connection will break if one small led will fuse.
You just need to remove fuse led bulbs also complete the connection again. As soon connection will complete all the bulbs will start emitting again.
There is one problem here, in most of the cases, other bulbs start fusing due to high voltage distributed between small LEDs. If you can replace fuse small led, it can do something good.
