Sony SLV-N50 broken audio?
 

I have a Sony SLV-N50

Recently, the audio stopped working.

It does not passthrough audio, it does not play audio from any tapes, it doesn't record the input audio - it just records quiet noise.

I cannot record, passthrough or listen to audio through rca and coaxial connections.

Video works though.

Is there a way I can fix it?

Oh, that's erm... Unfortunate.

Electronically I personally find the Sony machines the most robust out of the 'big three' (mechanically they can be a pest) but the component and build quality on the Sony VHS machines (in my opinion) tends to be notably higher than Panasonic or JVC so what you have here I guess is unusual.

There are of course diagnositc steps, are you competent with basic multimeter functions?

Is it possible the white and red RCA plugs have been accidentally plugged into the VCR input sockets instead of the outputs? It happens.

Yes. A multimeter shouldn't be a problem. What should I test on the VCR?
