I had just recieved a Bowser M630 with Lok V5. I switched the horn CV's and cycled through all 14 options. After a misclick on my MRC tech 6, the CV's refuse to change, but everything functions normally. Resetting the decoder hasnt worked either, is the issue in the controller or the engine?
I'm not at all familiar with the MRC tech 6. Did you happen to put a value in CV 15 or 16 by chance?

Also check the settings on CVs 31 and 32. You need to verify the correct settings with a manual from Bowser or the Loksound5DCC manual.

Usually bricked decoders don't work and can't be programmed. You do need to cycle the power after a reset.

In cases like this what will help is a fresh CV file (~140 kB in size; CV file is not Sound file 10-20 MB in size), which you can request from the manufacturer for free. Resetting CV8=8 in the ESU decoder doesn't restore all problems with incorrect programming.
