Bob,
If you are measuring 120 vac at each leg feeding the breaker box, there should be 120 vac on each buss bar that the breakers are attached to.
With the cover plate off, one can measure the voltage on each buss bar and on the output wires from each breaker (breaker in the ON position). If voltage on buss bar and no voltage on breaker output, bad breaker.
If no voltage on the buss bars, then the connections at the feed wires are bad. You may be able to remake those connections to correct the situation. Do so with the system de-energized.
