The system played fine for 5 minutes yesterday and then sound stopped and all lights on the pre-amp started flashing. It wouldn’t react to any of the controls so turned off at mains. Turned it on again and it played for 5 mins and the same thing happened - and it keeps happening.
Probably one for @NeilS However, in the meantime, a few questions: What else do you have connected to the NAC112? Are you using a dedicated power supply such as a Flatcap? Or are you powering from the internal supply of a Naim power amp, such as the NAP150?
When it happens does the power amp appear to switch off?
Hi - the flashing was very rapid - like 3 a second. But that has changed - it now plays for around 8 minutes and then goes dead. No flashing lights on preamp now but the Naim logo drops to half brightness.
No infra red sources in the room and nothing is in there that hasn’t been there for years - all very odd!
I tried the system with one source at a time plugged in - totally fine with all until the phono stage is plugged in to the preamp.
Regardless of the source, if the phono stage is plugged in, the preamp dies after a few minutes, although oddly, the phono stage light stays lit.
I had it playing here for hours, but not with the phono stage plugged in.
The flashing has stopped - when it dies the preamp logo drops to half brighness for a few seconds and then goes out completely.
So we have at least narrowed it down - I assume its something in the phono stage.
