You can expect this one back soon if you don't check every polar
electrolytic on all five major boards for leakage and ESR. We do dozens of
these and they ALL have between 60-120 bad caps causing all kinds of
frustrating problems. We don't even touch them unless the customer agrees
to a complete rebuild up front.
