I've just received my new Elinchrom D-Lite 4 kit in the mail today, and while opening it I was like a kid at Christmas! This is my first real lighting set, and I must say, the posibilities are rather exciting. In any event, I unpack it and set it up with no problems, turn it on, enable the modeling lamps, and... nothing. Turn on the slave circuit and my flash and test that. Yup. works fine. Check the fuses in the back. Perfectly fine. Check the bulbs. No scorch marks, looks fine. So, any suggestions as to what might be wrong? One light with a problem might happen, sure - but two lights with the exact same problem? Is it the bulb? The monolights? Or is there a problem between the keyboard and the chair, classically known in the IT world as USER = 1 D 10 T. Any insight?
