Red protection light on 200! Suggestions?

[ZincAlloy]

I asked Devialet to take a look at my D200 in January or February. It'd been 'inconsistent' in terms of sound quality and recently it started just making strange noises instead of playing music - only a couple of times but enough that I thought something was wrong. Guildford Audio took the unit back and lent me a loaner one, and it went back to Pedro (I think) at Absolute Sounds in London who replaced the power input board - the fairly simple board which has a Schurter filter attached and connects to the rear ICE socket.   I was slightly sceptical that this would make any difference but the unit has been absolutely fine since, and does seem to sound a little bit better too. In hindsight I think there may have been external factors explaining the inconsistency but I'm really not sure.
Took about 2 weeks all in all.

Thanks Rufus - will ask Devialet to check my entire device, to remove/minimise paranoia that there's something amiss, above and beyond current fault...
