Hi,

 

My N1 (N3 s/w) has stopped producing any sound (from any source, including speech, on any output). I have read in the service manual that there is a test disc, GGV1137, that I'm hoping will help me diagnose the cause (there is a sound playback feature, amongst other diagnostic tests not found in the standard service menu). Does anyone know where I can get a copy of this disc (or provide any clues as to what might have failed? A fuse perhaps?)

 

Thanks!
