logitech z323 fault

[beracah]

hi, I just plugged the system into the power supply socket, switched the power on and heard like a pop, thereafter system would not play music from the pc. Any test suggestions? does this system have an internal fuse?

According to Logitech there is nothing you can service inside the speakers. http/forums.logitech.com/t5/Speakers/Z323-Power-Issue/td-p/852134
There are quite a few of these for under $40 refurbished on ebay (bad units fixed by Logitech). Or if it's warranty, get them replaced for free.
