Optonica SA-4141 Problem

Does anyone have recommendations for me concerning my Optonica SA-4141? I powered it up and there is no sound coming out of the speakers, regardless of whether which input I chose (CD player AUX, phono, or tuner). I don't know if the worse case scenario (whatever that is!) is worth fixing. I will have to take it to a repair shop & pay for diagnosis & parts & labor to repair.

BTW I purchased this a year ago and never used it until now. I listened to it before purchase & was OK. It has been stored inside and treated carefully in my two moves since then.

Any opinions & feedback are welcomed!! Thanks,
