Problem sorted! On Brian's helpful recommendation I contacted Mr TechGuy and Steve. I decided to go with Steve because he is within a reasonable driving distance from my home, but thank you to Russ at Mr Techguy for your prompt and helpful reply.

As Steve had suspected, it was the PSU in my MS600 that was the problem. Apparently they are prone to failure. Figuring out how to get inside the MS600 was initially a bit of a challenge (Steve hadn’t actually worked on one of these before) but once that was done the repair was fast and straightforward.

Thanks Steve. Great service and a nice guy.
