Sunfire True Sub EQ

I have a 5 yr old Sunfire True Sub EQ that will not turn on. No previous problems. I have checked the external fuse.
I could take it to Snohomish, however they have told me they don't have all parts for the True Sub.
Any advice will be appreciated. I have noticed on other boards that sub woofers have power failure issues.

Ok the first 2 things I would check are
• Is it plugged in (I’ve accidently knocked plugs out of sockets before and didn’t notice)
• Is the outlet it’s plugged into have power (blown breaker)
I can’t help much beyond that without being there to check it out as I’m not that familiar with the component
