Receivers and Audio Components

Okay, time for one more question.  I recently purchased this receiver and it works great, except for one small thing.  When I turn up the volume to a loud setting (which I really do not do because I live in an apartment) the sound will cut out after a while.  It comes back on intermittently, but goes out a few seconds later.  The volume goes up to 50, and it normally starts after having it at about 32-34 for a while.  I have a friend who has another model of receiver that does the same thing.  Just curious what it is that might do this?  I am not really wa

Hi,

I have an AIWA NSX V2100 Mini System.  It has been sitting around forever and I want to sell it on EBAY.  Anyway, it works fine except the CD player will not rotate and the tray will not open/close when the button is pushed.  I have checked the fuse and wiring and it looks fine.  Does anyone know how I can fix this thing myself?  I need to make the tray rotate and the drawer open and close.  Thanks!

I have a Pioneer VSX 5400 receiver. How do I set the memory on the tone control for bass and treble and keep it to hold in memory? I have no manual, unfortunately.
