PS-CW450 wasn't at Samsung.com so that's a dead end. Take care and find the product service manual at samsungparts.com?

Hi,
my subwoofer Samsung PS-CW450 don't turn on. The led power is off. I removed the rear panel and verify that ac current is regular until print board. Now, I'd like to open the box for verify other components on pcb, but I don't know how to open the rest of the cabinet for to access at pcb! There is no other screws! Someone help me? Thanks.
