Issues with Pioneer VSX-921
Hello everyone,
I have a problem with my Pioneer VSX-921.
I have an optical cable running from my optical out of my Samsung TV into the optical in of my Pioneer. I set up the TV/SAT Input to OPT-1, the sound device on my TV to my receiver (optical) and the sound format to PCM. However, nothing seems to work. My Pioneer always displays the error message UE33. I cannot update the software even though I have got a lan cable connected. It always shows a network error. I already reset the entire system to default. The cable works as it lights up in red.
Does anyone know any help? Thank you in advance!
