Hi all, I received a Bose Lifestyle 20 system that won't turn on. There is no light in the display, and the sub does not get a turn on signal. I've been searching this forum and i found several hints, but none of them turned out to be the cure. I replaced all elcaps on the power supply board, and all voltages seem to be present. The 100 Ohm resistor in the sub is OK. Without schematics i'm lost. Any one have any more hints, or maybe schematics?
