Thanks Zos, you're pretty much saying what I thought. I took the power supply out earlier today and had a look to see if any caps (or anything at all) had suffered obvious failures but it looked pretty good. Minimal dust, too but I vacuumed it out, gave things a wiggle and put it all back together with no change in behaviour.
I'm only annoyed because of the scanner. I'll have to check whether I've scanned all of my 35mm slides. I scanned the last of my medium format stuff last year.
