After two weeks of operation, my QSI Aristo board has ceased to function in a really odd way. My setup involves the QSI Aristo board and g-wire receiver installed in a Bachmann K-27 that is controlled with the Airwire T9000 transmitter. I now get zero response on track power. On battery power (with my Airwire throttle turn on) I get zero response. With battery power on and the Airwire throttle off, the sound card starts up and the engine begins to move forward (uncommanded). I have no control even if I then turn the throttle on. I put the locomotive on the programming track and have zero communication with the quantum programmer.
What's really odd about this is the way it happened. I had been running on battery power for a little over an hour when suddenly my K-27 stopped abruptly. Assuming the battery was dead, I switched to track power and used the locomotive for another 5 minutes to put it away. During that time, I did notice the dreaded burning electrical smell, but couldn't find specific source (I had other engines operating at the time). The next time I took the engine out, everything was dead as described above. This is my first QSI install and I hope this is not indicative of QSI's quality.
For now it's back to straight DC track power for my K.

Update: I spoke with Lewis at QSI and he was very helpful. He had a couple of suggestions which I'll try tonight. The first was to reset the decoder using the reed switch and a magnet. He also mentioned that a few of the new boards got released with the ever problematic poly-fuse installed on the board. This yellow colored thermal fuse IS on my board. He suggested I remove the fuse and solder the wires together. The lastest releases of the board have this fuse removed. He also said that this work on the board won't void the warrant if this doesn't fix the problem. I'll let you know what I find tonight.
