I already sent messages to Axiom about this bit of "good fortune". Here's the gist of it.
This morning, in order to allow me to track down a hum on the surround channels, I moved my enternainment unit to reach the master power switch of the A1400. The front switch was also on. I think a connector that I had prepared in advance for dual center (and which was loose at the back) caused a short between a line input and a speaker post. Firework ensued (and even quick flames) for a few seconds before I could reach the power switch and turning the unit off.
As of now, no sound is coming out (not even the hum!). So, I think I literally blew it.
Grrr... I just managed to spend 40 minutes with it and it was beyond my expectations. This HAD to happen at 4h30 in the morning!
Hopefully this will get resolved within a reasonable amount of time.
Not a happy man right now.
