No Audio Output from S-DJ05 (Power and Control working)

Hi guys!
I am having an issue with one of my Pioneer S-DJ05 speakers. I believe I have an internal problem. As it powers up fine with all the lights and controller functioning. Also I have troubleshot cables and power cords etc. Even swapped the control cable around and still the same thing.

I experience pure silence. So it's like there is no signal at all. 

Is there an internal fuse or maybe a connection that could have came loose?

Any help is appreciated.

Regards,
Micky
