Hi amstok

Sounds like it may have a DSP failure. Straight stereo signals bypass the DSP stages. Could be an expensive fix. I suggest you take it to a Hitachi agent for a quote. Not something that can be easily fixed on the kitchen table I am afraid.

Hello Bernard, your Pioneer AX-311, is a two-channel, stereo amplifier, you can connect your Samsung TV, if it has audio output L and R, to an input of the Pioneer, say for the AUX input, what will get, is to listen to the sound of the TV in your Pioneer, in stereo, two channels, you can not have surround sound, because your Pioneer does not have that benefit
At the most, you can hear the sound of Samsung on the TV and the amplifier simultaneously, and you will hear a sound delay between the Pioneer and the Samsung
I hope my answer was useful

Hola Bernard, su Pioneer AX-311, es un amplificador de dos canales, estereo, usted puede conectar su TV Samsung, si tiene salida de audio L y R, a una entrada del Pioneer, supongamos por la entrada AUX, lo que va a obtener , es escuchar el sonido del televisor en su Pioneer, en estereo, dos canales, no podra tener sonido Surround, porque su Pioneer no posee esa prestacion
A lo sumo, podra escuchar el sonido del Samsung en el televisor y el amplificador simultaneamente, y se escuchara un retardo de sonido entre el Pioneer y el Samsung
Espero que le haya servido mi respuesta

If you are running this through a cable box then you need to run a separate pair of audio from the box output to the input of the TV. If This is from a stereo system then you need to run audio from the cable box to the stereo component and select the proper input after it is turned on.

Just a thought - you have also selected the appropriate input on the Hitachi?

best bet is go to there internet site and then support download the manual

surround receivers are supposed to be able to turn a stereo signal into a surround signal.  if the surround unit is producing just a stereo sound, then the tv is most likely outputting in mono, and not stereo; or there is no surround sound to decode..

Hello Alan, I have the cable from a u/s AX-M71 system. the cost is £8.00 including P & P . Regards, Malcolm

Sounds like your audio output IC is bad.

the red green and blue are component video
to get the surround sound to work the red and white audio outputs from the tv go to the audio inputs on the reciever , and to get the digital surround sound the optical also has to be hooked up
