I have a psw505 that’s not powering up? I’ve had it several years, was working great now nothing. My question is if the fuse is blown will this cause the unit not to come on?

    Yes, but it’s likely not the fuse. The amp has failed and will need replaced.

    I checked fuse which is fine. Is there a way to check to see exactly what’s wrong?

    If you are an electronics tech with expensive test equipment, then sure.

    Subwoofer plate amps are very Expensive to fix and generally not worth it. This one would work fine but the enclosure might require a little modification, but you can get a whole new sub for not much more:

    Check the subwoofer level in your avr. If it’s too low it won’t trigger on the sub at low volumes.
