UnitiServe SSD: Power Supply failure? (blinking vaguely and irregularly ...)

Is there any way you could check the output voltage from the power supply? This will give you an answer if it failed.

Michael,

have you contacted your dealer, distributor or Naim?

Not yet, got hospitalised directly after returning from holiday - expecting to go home today though. 

Just thought there might someone out there who have had similar experience and knew exactly what it could. But I will drop Phil a note ...

I know, but unfortunately I don't have a Voltmeter .... Just thought someone may have experienced the same and knew what it could be. Power supplies should be something that last forever ... maybe not.

The other thing you could try while you wait for a response from Phil could be to connect a VGA display to the VGA socket on the back of the Unitiserve. You will be able to see where it gets to in its boot up.

But if the light on the power supply itself is blinking irregularly or at all cone to that, I think this is certainly going to be a power supply failure and the good news is that getting a new one won't involve sending your US back to Salisbury.

Incidentally switched mode power supplies are only reliable if they are over-engineered or carefully designed to be completely reliable and I don't think the US power supply is either of those. Rather Naim have balanced cost and performance. Also most failures in such devices occur at switch on due to the high current surge through cold components. Anyway see what Phil says....

As I don't see any signs of life in logo-indicator on the front panel, I suspect that it doesn't even begin the power up. 

Just wrote Phil, so will wait for his reply.

(... and who has a VGA device nowadays? ... I could maybe buy an adapter for my Apple display ... I only got devices from the fruit company :-) )

I keep an old VGA display in my loft specially, although I have never had to use it on the US!
