I have 2 of these floodlights. Both are original post-war, silver towers. One I bought a few years back, one is from my childhood set, probably 50's vintage. They are FRUSTRATING. Sometimes they will come on when I turn on the power, sometimes not. They never, ever, stay light for an entire operating session. i've resorted to the "yard stick" disciplinary action which works, occasionally. I don't see anything visible that would cause this...any suggestions for trouble shooting would be welcome. Iv'e moved and tried to ensure the brackets holding the lights is firmly attached to the black pole running down the center; checked the fahnestock clips and they seem secured and the insulator on the bottom of the clip attached to center pole looks fine. I've wiggled the bulb holders a bit to be sure they are contacting the holding arms...and I've bent slightly the entire bracket that holds the lights. Nothing has been a permanent fix. Oh, yes, I've ensure the wires supplying power and sound are OK. Power is constant per the meter.
Yardstick techniques: the following work, but not always and not permanent...bang the tower, bang the floodlights, bang my head....
thanks,
