Are you knowledgeable enough to use a volt metre and check voltages with the unit turned on? If you have no output whatsoever...no thermal noise, no motorboating, etc...you might just have a 'shagged' power supply, which could be an easy fix (a coupla' few cheap semiconductors, a dead resistor, filter caps...hopefully not a transformer). It could also shock you but good (usually won't kill you - just don't stand in a bucket of water).
There are several places you can get practical advice on checking power rails...I'm usually the guy who sticks his hands in and gets whacked first.
Wait- you said that you at least got the power indicator on. That probably means output issues. You might want to look at a schematic, if possible. Even one from a similar unit can give you some indication of where in the circuit you should be reading voltages.
Thanks for your reply, you're truly a gent. I'll look for the schematic and see if I can make some sense of it all.
