Help,
I came to the internet hoping to answer the same question?
Half lit Christmas Lights? 100 light set, half lit, even brand new sets.
Usually there are fine when you check them BEFORE you put them on your outdoor shrubs etc., and THEN when you turn them on, half the set is out!
And yes, I went through all the steps, New fuses, jiggling the lights etc.
H E L P !
Oh well at least you are not alone.
I really would like to have this dilema solved if anyone has an answer, please feel to E-mail me.
