"Crushed"

Sirs, I'm writing in regards to my SP2500 High Power 2.1 PC Speaker System's "Desktop Controller with attached interface cable" It seems the Controller has a "Crushed" Power On-Off Button, and will not respond to being turned on. I do not know if I should send the Controller back to you for repair / Replacement, or should I purchase a New one from you. I gather there is no user serviceable part's inside. And I do not have the Purchase Information (I have had the SP2500 now for about 1, 1/2 year's)... Thank You
