This question is the one that I had in mind. It seems to me that it's similar to this question, basically a version of "Something bad happened to my X system ... what happened/how can I fix it?"
Both questions seem to me to fit on this site well, but the first question also seems like it could be easily answered by someone from electronics.SE. Is there some way to attract attention from Electronics people so someone can provide a technically accurate answer (based on the OP's description) while also leaving the question here, or is it better to migrate (or flag to migrate) the question because it could be better answered somewhere else?
