I recently purchased a used 1050, which was sold as being functional. When it arrived, it powered up, but no sound comes out of the speakers, and the front panel is very dim. I was wondering if there were any pointers to things I might check to see if I could fix them easily. Unfortunately, shipping the amp to outlaw is something I'd prefer not to have to do, as I'm in alaska, and shipping is rather rediculous from here...
