Ok, made some research, check that the loco has a green PCB, so took my chances and put an mLD on it, made the settings for a C-sine motor and the engine is running lovely, i assume then that the the decoder is fried, will contact the seller to see what can be done, sending it back will cost me around 50 euro, i think that for 50 more i can put an extra mSD on my next decoder order......

Hi Tom, well i have tried the original decoder several times, putting it in an out of the plug, and nothing, to test it in MM2 i deactivated mfx and DCC on the CS2.
After putting the mLD the upper lights front and rear did not worked.....with burned leds perhaps it would be on the post right now, but a more careful inspection shows that the corresponding SMD were wired independently and connected to Output 1 and 2, with the proper mapping job, they work fine now.
Anyway, the original decoder will not end in the garbage right now, will do eventually more tests and it will be thrown up in about 1 or 2 years, as its ussually happens with dead decoders...
I will not send the set back, that is for sure, no matter what answer i get from the seller......
Mechanically it is in mint condition, as described in the listing, it will get perhaps an mSD on the future or remains with the mLD wich i took from a nice BR03 from the Berlin 3100 set, wich i think will behave lovely with some nice sounds.....
Cheers
