Hmm, have you tested the same flash w/ synch cord on another camera? If it works, then the synch on the Kiev might be broken (there was a long thread about this problem on
http://www.beststuff.com/forum/list.php?f=21
recerntly). Or do you have another flash to test on the Kiev - if it works, it's the flash that has got the problem (I have one Vivitar 283 that only fires when using the hot-shoe, not with the PC contact, and had been wondering for quite a while, whether the camera or the flash was the culprit).
