The output amp section for your system is not designed to run more than the speakers that come with it. By adding more, you presented too low an impedence load to the amp and overheated it. This occurred too quickly for the internal protection circuits to kick in to prevent damage to the outputs. This unit will now require that the outputs be replaced. These are not the easiest units to work on, so I would not suggest that you attempt this repair yourself. Expect a parts cost in the $35 range for this repair.
if your sistem got auxiliar option,you can connect your pc through the earphones output of the pc to the auxiliary inputs on the shelf sistem they are a cable named 3.5mm to rca outputs to fit that connection gfood luck
The optics assembly is having a problem. Either it can not read the disc at all or the disc is not spinning. In any case, the unit will require service. If you can reach the lens, try cleaning it using a cotton swab and alcohol. That may resolve the problem. If not, update this. Please try to see whether or not the disc spins and report that as well.
