Tony,
Here's a reply I got from TCS support when I had similar sounding issues with a couple of M1 decoders I have. I have several I picked up at a S-S quite a number of years back that tend to go a bit crazy now and then. The instructions work, but some times I need to fiddle with/repeat the steps a couple of times:
There was a known bug in older decoders where if CV1 was programmed to 0 or to greater than 127, it would either fly off the rails or do nothing at all. My first suggestion would be to use your programming track to set CV1 to 3. doing so will automatically return the decoder to short address. While you are on the programming track, read the value of CV19. If it is anything other than 0, set it to 0. Return to the main and try to run on address 3. If you are successful, set up your long address (if necessary), or return to the programming track and set your short address in CV1 (1-126). CV1 cannot be modified on the main via OPS programming. When setting up a long address, either do so on the programming track, or ensure you are following the correct order of operations on the main via OPS:
Use the address calculator to determine the values of CV17 and CV18
Set CV17 and CV18
Set CV29 to long addressing using the CV29 calculator
Hope that helps.
