    Hi,

    I've got three non-working Vivitar 560D flashes that I want to try to
    repair.. What are the most likely components to fail (it looks like
    there're at least 6 capcitors in it). Is it possible to test components
    in-circuit without removing them (I generally thought it not)?

    Thanks,

    The main problems I've found in Vivtar flashes was either the trigger
    coil or the main capacitor.
    The cap is very pricey and hard to find.
    Vivitar charges almost as much as a new flash for one.(About 30 bucks
    for a 283/285 cap.)
    Do a google for camera repair/restoration groups or clubs to find the
    latest on DIY photo repair.

    I had a similar situation with 3 SubSea underwater strobes, except the company
    has been out of business for over 15 years, no information to be had. Anyway,
    first thing is to determine what part of the circuit to attack. For instance,
    does the strobe oscillator "squeal" and charge the main capacitors but not
    discharge them? Or is are the units totally dead? I was lucky in that one of
    my units would charge, but not flash. Used that to compare components to the
    totally dead one. Got that one to charge and it flashed. I then used that to
    compare components to the first one, and so on. Good luck.

    Another thing I tought of is to check the batteries or temporarily wire some in
    the circuit. Are they totally dead?
