Question about Audio Shelf Systems
I've already gotten a response to this. I'm not saying he's wrong but i would like a second opinion. I get a huge BANG!! out of my SA-AK57 mini-system then it shuts off with an F61 error. It happens only when the unit is first turned on, after the bang happens i can turn it up as loud as i want cause i know it won't happen again, untill the unit rests for a while. sometimes i get a slightly softer bang and it doesn't turn off....i'm pretty sure one day its just gonna not work. I really love this thing awesome sound, really loud and clear...I'm hoping that the fix isn't too much money
This sounds like a power disconnection problem.
you have a large amount of components, on the motherboard that charge up with being used. ( namely fets/capacitors et,c ) when your system is powering off the instant disconnection of mains power, can cause a Bang or Pop to the speakers.
I,d suggest trying swapping the speakers over from right to left and vice versa. see if the errors still there.
Also try turning the volume right the way down, before switching off. is the bang quieter ?
Check the mains cable ( plug end ) see if theres a broken or loose wire at the plu ( causing an arc ) finally check that the plug ( cable grip ) plastic tang that holds the cable, has,nt been overtightened and damaged the cable underneath it.
I hope any of this helps you to a self diagnostic rectification of the problem listed. Also try without speakers is a suggestion.
