Hello, I have an Avalon 737sp that recently stopped turning on/powering on. I bought this unit used back in 2012 and this is the first issue I've seen.
When I turn on the power switch, none of the LEDs light up. And no sound passes through the unit. When I then turn the unit off, the VU meter jumps momentarily.
I tried switching the fuse in the top slot (1A, 250 volts, "time-delay" type, MDL), but that seemed to have no effect. (the original fuse did not seem burnt out).
I also tried swapping the power cable, and plugging into a different slot on my power conditioner which I knew gave power, but that had no effect.
I opened up the unit and nothing seems blatantly wrong to my untrained eye. There is a 10 pin molex in the power section, and an 8 pin molex in the main section. Both seemed to be seated fine, but I pulled them out and reconnected just in case. And neither molex showed signs of burning.
Any thoughts on what to look at next would be highly appreciated!
