I opened a new box of 200 Christmas mini lights (not LED) and 50 in the middle do not work. There are no missing or broken bulbs. I checked the 50 unlit bulbs to make sure they were seated tightly and they are. Do I need to check the ones that work? I know this is not a big problem in the scheme of things but I already put them up on a large outdoor tree. Would this indicate some sort of individual bulb problem or a fuse problem or a wire problem? I can reach the 50 unlit bulbs and the plug as fortunately they are on the lower part of the tree. Thanks if you have any suggestions.

A 200 light string is actually 4 50 light strings wired together. Each bulb contains a shunt that allows the section to work if one bulb burns out. I often find these shunts fail at an alarming rate. If this was new, return it.
