My Corsair SP2500 again got screwed

Last week my, while running my PC, my left leg accidentally hit the UPS from APC, in which my PC, display and speakers are connected. There was a sudden burst spark sound. As a result the speakers have stopped generating sound. The display of that speakers control console, which displays, sound, bass and other things is working. When I connect my headphone to its control, I am able hear. Even my PC detects speakers. But there is no sound.

Can someone suggest me a solution to this?

crack it open and look for any blown capacitors/MOSFET. check your power rails.. use your nose and smell around... if its digital, then your basically SOL. Good Luck Mr. Maverick.
