Fault Code 61

No experience of Fault 61, but plenty of experience of random 1 off fault occurrences with computer systems; they occur for many reasons, but the most random of which is an alpha particle strike on a memory cell or a processor register!

  Does that mean I need to house it 500m underground in a lead mine ???

Mike, that's definitely not what you need...

Lead is a decay product of Uranium 238 which is an α emitter (along with at least 10 other α emitters in the decay chain).

However none of those α particles will get through the plastic encapsulating the chip...  No, the reason for not living in a lead mine is the toxicity!  

Phew thats a relief, I was looking to see if I had any lead bearing strata under the garden.

Seriously though, I was aware of alpha strikes as we had a few experiences with marine data logging via satellite comms in my previous life. I understood the event risk could be reduced by better engineering/design & that was introduced about the time I retired so I did not see how effective the changes were.     That said it did not occur to me that this might be a cause of code 61.   Reading forum threads on this I previously said there was not much info, but there is mention of software corruption. Given that an alpha strike can cause minor disruption, data & software corruption some of which can be permanent defects, I'm still left concerned.

Anyone from Naim have any comments ???

I kept getting Fault 35 at seemingly random times. After too much work/thinking/yelling/praying, I discovered that Netflix was messing with both my NDX and ND5.

i had Fault 36 for a couple of years until Phil Harris recommended I send the unit back for a check. Turned out to be H/W problem. Now fixed.

I had fault DYLX, so I went to see a psychologist: She said I had dyslexia!

Still not fixed!
