Subwoofer PSW505 not turning on

My subwoofer PSW505 randomly stopped switching from standby to on mode. The sub does not turn green even if manually put on the On mode. There is no sound coming out. My guess is that the amp plate needs to be repaired or replaced since the fuse is ok on it. I am a big fan of your audio equipment and would be disappointed to see this nice sub go to waste. I have some of your equipment back in Europe too.

Best,
