Accessory Decoder dead?

[gilbo2]

One of my accessory decoders has stopped working. Looking at any cv they are all coming back as 255. Have reset the unit setting cv8 to 8 but this makes no difference. I assume it is dead and needs returning to Hornby for repair? If so, how long does that

 

normally take?

Sounds like you are right. 255 means it is not getting a return from the decoder.

 

Sorry, no idea how long for Hornby to repair or replace under warranty if less than 12 months old.

just a suggestion.....

 

I have had a problem using a DC power clip causing reads from CVs to return 255 due to the cap in the power clip.

 

did you change your power clip recently by any chance?

for the suggestion, I don't use power clips everything is soldered up to the pad's screw terminals. I have a "bank" of 7 pad's and its just the one that has died.

There were clearly some reliability problems with the 8247s a few months ago from the reports in the forums. Makes me wonder if the lack of supply now is just that, or if Hornby decided to withdraw a faulty batch to cause the problem.
