I've really loved this AV-10 ever since I found it and I did some button repairs on it and it worked great for a while until last week when the standby light comes on but it won't turn on. I've checked the amplified IC stages for shorts and cannot find anything wrong. Capacitors visually look fine and my speakers are still good as well. I never even power the thing over 10 watts (I use it mostly for its spiffy optical inputs). But when I opened it there were dustbunnies galore on the power supply section-- so heads up! Sucking it away with a vacuum cleaner once every 10 years might be a good idea...Just wish there was a Service Manual I could buy somewhere :'( The power amp pcb actually disassembled completely from the unit which is cool...for easy replacement I'm sure. but with that disconnected it still doesn't turn on (standby light still there)...so I'm a little baffled. Any ideas much appreciated and I can take pics too if that will help describe things better. Thanks in advance!
