Some of the bulbs have some sort of bypass circuit, so that when one bulb out of a large number blows, they don't all go out - which makes it very difficult to find the dud.

The more that fail then the more strain is on the others so keep your eyes peeled for lamps that are out and get them changed quickly. If it blows again, think yourself lucky you didn't just leave the blown bulb in place and soldier on without.If your Christmas tree lights are still not working after changing the fuse and checking the bulbs, you may need to throw them away. But if you connect too many lights to one power source, you'll probably overload the circuit, pop a circuit breaker in your electrical panel, and have no lights. If they really are bulbs with a filament in and they run at mains voltage then it should have four fuse bulbs, one for each circuit.

Short answer: other bulbs are now getting a slightly higher voltage, new bulb blew but maintains circuit or inserted wrongly in socket.They certainly wont all go off if one LED open circuits, there are different ways of connecting LED`s, all in parallel, or in groups of series connected ones, with the groups all in parallel.
