No audio output via RCA or Optical
For many years, I have ran RCA cables from back of this flat screen, to my Carver preamp’s video 1 input. Recently, the signal went bye-bye. I tested all the pre-amp’s RCA inputs and all work properly. Thinking there might be an issue with the RCA audio out’s of Vizio, I bought an optical cable and an optical to RCA converter This did not work, leading me to believe the issue lies with the audio outputs on the Vizio. Has anyone encountered this? If so, what is the solution?
Questa è una buona domanda?

What are the chances that if the RCA connections are burnt out of the optical will be to?

@Alex Couch
The actual connections both won't be burnt out.
As one is analogue output and the other is digital the most common factor to both would be the audio amp.
The DSP (digital signal processor) in the TV would send the audio signal derived from the input signal, to the audio amp where it would be sent to the RCA connections and the optical connection as most TVs only have the option to select internal or external audio output i.e. internal TV speakers or external audio amp or speaker and not then to either the RCA or the optical
