Ugly1 has identified the culprit relay, AFAIK.

This came up before, more than once. A while back, I cooked up a theory that something was causing the green conformal coating on the board to liquify... a long-winded spiel involving the mysterious syndrome known as "plasticizer migration."

Some time later, a respected source [meaning a guy on another forum who always seems to known his sh**] mentioned the green goop issue and said there may even be a BSP about it. The leaky relay was said to be the culprit, if my memory is to be trusted. [This was years ago.]

Paging Mr. Bloom...
