Receivers and Audio Components

Hi!

I'll state right off that I'm new to this 'community' so if I'm rehashing a previous question; my apologies in advance...

Simply put I received a Mini-bookshelf stereo that does power on but will not generate any sound. All the function buttons appear to work properly (AM/FM, CD & AUX) and the CD player loader works as it should. There are no warning lights, strange noises or mechanical errors I can detect except for the fact there is no sound.

Hello all! My son got my older kenwood amp the other day and ran speaker wires wrong causing the amp to blow fuses! I replaced fuses with fast acting and they would just blow! A friend said I needed slow blow fuses because of the amound of current at start up! I tried the slow blow fuse and it didnt blow them this time! Well I have lights now but no sound! Also its not heating up like it use to! I know a little about electronics, but this has me stumped, because I open the case and there is no sign of burnt op amps or blown caps!

i have a pioneer vsx-d601 receiver and i cannot get any sound through my speakers when hooked up i am using brand new speaker cable and know that all of the speakers work. two days ago two of the 5 speakers hooked up worked and now i cannot get any of them to work. is my receiver broken? and how would i hook up the sub? with just regular speaker wire? thanks
