Help with 5.1!

I just bought the logitech X-530 speakers. All of them are working but the center and rear left! . I have set everything up to 5.1, drivers are updated. I cant get those working, i hope there isn't something wrong?



suggestions?

is it hooked up to a soundcard or is onboard?

my onboard is 5.1.



Im taking it back, hooked it up to my TV and still same problem. Opened the back of the amp, seems to be toasted.. how the hell when its new?!

where did u order the speakers?
