Infinity Interlude IL120s Powered Subwoofer (home) will not power

I have an Infinity Interlude IL120s Powered Subwoofer that suddenly will not power up. It just stopped working one day last week. I've tried changing the external fuse to no avail. Has anyone had this problem and do you know how to fix it? The warranty has already expired. :(

    Hi MrScary66613,



    I accidently put my problem under a car subwoofer category instead of home. I'm new to this site and for me right now, it's poke and hope on how to add a new product. Do you have any experience with the home models?



    Thank you,



    Lisa

    I will try to help ya anyway. Unplug the Sub and Remove the Back Panel. Check the Internal Circuit Board for any Breaks in the Board Tracer Wires or For Fuses. Let me know what you Find.

You can connect the radio to any standard 12 volt DC power source, with either a positive or negative ground. If you don't know whether your power supply uses a positive or negative ground, consult the manual for your power supply or contact the manufacturer.

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.
