I have an RMA from the distributor and Naim will take care of me -
but was wondering if there’s something I can try at home - my ND555 lost one channel through DIN out. Tried a few DIN cables but same issue - and these din cables all work on other systems I have at home.
The rca out works. System is ND555/552/500.
Thanks in advance!
Tried rebooting and factory resetting the unit.
Not sure how to apply firmware again …
I agree with @Gazza that it’s likely to be a stuck relay and is a known issue with some batches of relays. But as @Richard.Dane identifies it’s very important to check whether the problem is with your 555 or your 552, or you could be returning the wrong black box.
Using a RCA to Din cable and it is working just fine. I thought there might be a trick - like knocking twice on the box or putting transit screws on and shaking to unstick stuck relays or something else…
