I have a Denon AVR 500 system.
This is connected to a TV.
The picture and sound suddenly go off .
The amplifier is working independantly and the TV is also working alright.
Is this a problem of optic fibre cable . How do you clean the optic fibre cable. We can see a light at the terminal of the cable.
Please advice
