Brian, Fix it. I said this before, and you expressed some concern about safety. I wouldn't be afraid about attempting to make changes to see what it might take to fix the product - you won't know until you try. I personally HATE having to fix an OEM's problems. Each change would have to evaluated and documented as to how this affects safety. A ferrite clamped on an internal cable will "most likely" not affect safety provided it is secured in place. A line filter could be a problem, but even that can be justified by a few simple tests and some documentation.
In one case, I found that the conducted emissions on an OEM component were reduced by REMOVING the line filter. All other tests were also positive. In this case, the OEM was more than happy to cut cost from their product by removing the filter. (I still wonder if someone out there who was using the same OEM was suddenly baffled as to why they were suddenly failing EMC when they had once passed? SORRY!) "it passes when we test it" If you are an OEM and you say this to me... aaahhhh I won't go there.
