2e0dtoeric Posted October 15, 2017 Share Posted October 15, 2017 First off - what controller are you using?Second - although Hornby haven't said so, there seems to have been a bad batch of decoders released, with faulty sound amplifiers.-Have you tried a factory reset of the decoder? If that doesn't fix it, all you can do is send it back to Hornby and ask them to test it. Hopefully if it is the chip at fault, they'll send a replacement.

stuart_mclean Posted October 15, 2017 Author Share Posted October 15, 2017 using railmaster on a purpose built PC. I have emailed hornby as I suspect it is a bad chip but I thougt it was worth asking as I might has accidently caused the fault. I tried the reset to no effect. The comment about a dad batch might be the answer. Thanks. Link to comment Share on other sites More sharing options...
Fishmanoz Posted October 15, 2017 Share Posted October 15, 2017 What exactly do you mean by saying all of the CVs have gone? Do you mean you get no value when you try to read them? Or do you mean the list of functions have disappeared from the loco when you call it up in RM? Particularly if if the latter, but in either case, delete the loco from your loco roster, download and install the very latest version of RM from the link at the top of this forum, then call up and install the loco in your roster using the correct R number for your TTS loco (or if installing a chip bought separately into a loco other than the intended loco, first call up the intended loco by R number to get the correct functions then edit to get your correct loco description and photo). If the sound now works, you’ve solved the problem. If it doesn’t, then dud decoder will be most likely. Link to comment Share on other sites More sharing options...
96RAF Posted October 16, 2017 Share Posted October 16, 2017 Two things in RM 1. Does RM pickup up in CVs 7 & 8 that this is a TTS decoder. If so it will load the TTS CV set to reaad. 2. At the top of the read box do you have the full range of CVs set as RM will only read the range you ask it to - e.g. 1 - 10 or 1 - 255 or 1 - 1024, etc.Rob Link to comment Share on other sites More sharing options...
