DL4100 enclosure repair

Like a few others have reported, my DL4100 enclosure failed recently. I was able to put the drives in a PR4100 enclosure and get everything up and running without issues.

Now I have a semi-redundant DL4100 drive that doesn’t work. It feels like it ought to be repairable, but I can’t find anyone who claims to be able to repair it (UK based). Does anyone know if these can be repaired, and if so by whom?
