Where can I get powered studio monitors repaired?

I’ve got a pair of old KRK Rokit 8 studio monitors. I think they are 1st gen. Some years ago they both stopped working. Just wouldn’t turn on. I thought the fuse may have blown, it had one replacement. I replaced it and when I switched it on, it immediately blew the new fuse. So I’m not sure what’s the issue, something electrical it seems.

Anyhow I’m looking for a place locally who knows their way around these and can repair them. Any suggestions? They are way out of warranty, as I bought them so long ago.
