I inherited this amplifier and kept it at my
cottage where I could enjoy it a little more then in my small apartment in the
city. The problem I am experiencing is that, it was left on for a week by
people who used my cottage and when I went to use it the next weekend I couldn’t
get any sound out of it. I am looking for an authorized service agent in the Toronto area to take it to, but does anyone have any ideas
why I can’t get sound when everything else seems to power up just fine

Crown utilizes small signal transistors as thermal tracking devices but i think that this is not the main issue with the amplifier, it could be in the output stage with some power transistors failure, does the other channel works fine?
I couldn't tell you if the model supports hdmi, apart from saying if it has got an hdmi socket it should (in theory). But I can say that if you want full 7.1 sound then though your blu ray can play them back (movies) in that sound, you won't hear them in that. It depends, if you want to experiance the full 7.1 sound, then you need a new amp and the two extra speakers.
No that's how to describe a problem, folks - with details. Using internal FM as the source is always the preferred way of troubleshooting system-wide receiver audio problems (no cables or setting in the way).
Does the sound come on immediately with power and then fade or is there a small delay while the electronics stabilize, a click and then sound that fades?
The fizzle probably means something is rapidly overheating or a capacitor is malfunctioning. If both channels do it, I'd suspect a common power supply problem. Can't help much more than that.
You need to determine if the power is getting to the audio amp section. For instance with the volume full up is it humming etc? As a 'rule' it's unlikely that both left and right channels will fail at the same time (unless you have done something silly with the amp) you are looking for something that is common to both channels. Which is why the power section is first suspect. The exception to the rule (above) is where amps use say an IC power amp for both channels. You will find this IC on the big heat sink. Check whatever is on that anyway for damage or burning. The only other area could be the pre-amp part. Again this could be a single IC controling both channels, so it's failure could cause a loss of sound. By the way if you can hear music/sound coming through when you put it up to full volume the pre-amp will be generaly good.
